We characterized patterns of population subdivision, and tested hypotheses associated with locations of potential Pleistocene refugia and the relative contribution of these refugia to the post-glacial colonization of North America and Scandinavia by common eiders (<i>Somateria mollissima</i>).

Whereas spatial differentiation in nuclear genes was concordant with subspecific designations, geographic proximity was more predictive of inter-population variance in mitochondrial DNA haplotype frequency. Inferences of historical population demography were consistent with restriction of common eiders to four geographic areas during the Last Glacial Maximum: Belcher Islands, Newfoundland Bank, northern Alaska and Svalbard. Three of these areas coincide with previously identified glacial refugia: Newfoundland Bank, Beringia and Spitsbergen Bank. Gene-flow and clustering analyses indicated that the Beringian refugium contributed little to common eider post-glacial colonization of North America, whereas Canadian, Scandinavian and southern Alaskan post-glacial colonization is likely to have occurred in a stepwise fashion from the same glacial refugium.</p><p><strong>Main conclusions </strong><span>&nbsp;</span>Concordance of proposed glacial refugia used by common eiders and other Arctic species indicates that Arctic and subarctic refugia were important reservoirs of genetic diversity during the Pleistocene.

We estimated transition probabilities from wintering locations to breeding and nonbreeding by using multistratum robust-design capture-mark-recapture models. We also examined the effect of breeding on migration to wintering areas to assess the hypothesis that individuals in family groups occupied higher-quality wintering locations. We used 4,538 unique female brant in our analysis of the relationship between winter location and breeding probability. All competitive models of breeding probability contained additive effects of wintering location and the 1997–1998 El Niño–Southern Oscillation (ENSO) event on probability of breeding. Probability of breeding in non-ENSO years was 0.98 &plusmn; 0.02, 0.68 &plusmn; 0.04, and 0.91 &plusmn; 0.11 for females wintering at BSQ, LOL, and LSI, respectively. After the 1997–1998 ENSO event, breeding probability was between 2% (BSQ) and 38% (LOL) lower than in other years. Individuals that bred had the highest probability of migrating the next fall to the wintering area producing the highest probability of breeding.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"American Naturalist","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"University of Chicago Press","doi":"10.1086/662165","usgsCitation":"Sedinger, J.S., Schamber, J.L., Ward, D.H., Nicolai, C.A., and Conant, B., 2011, Carryover effects associated with winter location affect fitness, social status, and population dynamics in a long-distance migrant: American Naturalist, v. 178, no. 5, p.

Less was known about migration routes and breeding distribution of pintails in East Asia. From 2007–2009 we marked 198 pintails on their wintering areas in Japan with satellite transmitters to: 1) document spring migration routes and summer distribution, 2) evaluate migratory connections and breeding season sympatry with North American pintails, and 3) determine if pintails used the same migration routes in fall as in spring. Most pintails (67%) migrated to the Kamchatka or Chukotka peninsulas in eastern Russia either directly from Japan or via Sakhalin Island, Russia. Remaining pintails primarily migrated to the Magadan region or Kolyma River Basin in eastern Russia via Sakhalin Island. The Chukotka Peninsula was the most common summer destination, with highest densities in the Anadyr Lowlands; a region also used by pintails that migrate from North America. One pintail migrated to St. Lawrence Island, Alaska, in spring and another briefly migrated to the western coast of Alaska in fall. Autumn migration routes generally mirrored spring migration although most pintails bypassed Sakhalin Island in fall. Compared to North American pintails, pintails that winter in Japan exhibited less variation in migration routes and breeding distribution, and nested at higher latitudes. In the Russian Far East there is no region with habitats comparable in extent to the ephemeral mid-latitude wetlands of North America. Consequently, East Asian pintails mainly nest in arctic and sub-arctic regions where annual consistency in wetlands promotes constancy in migration routes and breeding distribution. Breeding season sympatry between pintails from different continents results more from North American pintails migrating to eastern Russia than from Japanese pintails migrating to North America.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Avian Biology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Wiley","doi":"10.1111/j.1600-048X.2011.05320.x","usgsCitation":"Hupp, J.W., Yamaguchi, N., Flint, P.L., Pearce, J.M., Tokita, K., Shimada, T., Ramey, A.M., Kharitonov, S., and Higuchi, H., 2011, Variation in spring migration routes and breeding distribution of northern pintails Anas acuta that winter in Japan: Journal of Avian Biology, v. 42, no. 4, p. 289-300, https://doi.org/10.1111/j.1600-048X.2011.05320.x.","productDescription":"12 p.","startPage":"289","endPage":"300","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"links":[{"id":271744,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":271743,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1600-048X.2011.05320.x"}],"volume":"42","issue":"4","noUsgsAuthors":false,"publicationDate":"2011-07-13","publicationStatus":"PW","scienceBaseUri":"51838aece4b0a21483941ad5","contributors":{"authors":[{"text":"Hupp, Jerry W. 0000-0002-6439-3910 jhupp@usgs.gov","orcid":"https://orcid.org/0000-0002-6439-3910","contributorId":127803,"corporation":false,"usgs":true,"family":"Hupp","given":"Jerry","email":"jhupp@usgs.gov","middleInitial":"W.","affiliations":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true},{"id":117,"text":"Alaska Science Center Biology WTEB","active":true,"usgs":true}],"preferred":true,"id":478242,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Yamaguchi, Noriyuki","contributorId":83397,"corporation":false,"usgs":true,"family":"Yamaguchi","given":"Noriyuki","affiliations":[],"preferred":false,"id":478249,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Flint, Paul L. 0000-0002-8758-6993 pflint@usgs.gov","orcid":"https://orcid.org/0000-0002-8758-6993","contributorId":3284,"corporation":false,"usgs":true,"family":"Flint","given":"Paul","email":"pflint@usgs.gov","middleInitial":"L.","affiliations":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true},{"id":117,"text":"Alaska Science Center Biology WTEB","active":true,"usgs":true}],"preferred":true,"id":478243,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Pearce, John M. 0000-0002-8503-5485 jpearce@usgs.gov","orcid":"https://orcid.org/0000-0002-8503-5485","contributorId":181766,"corporation":false,"usgs":true,"family":"Pearce","given":"John","email":"jpearce@usgs.gov","middleInitial":"M.","affiliations":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true},{"id":117,"text":"Alaska Science Center Biology WTEB","active":true,"usgs":true}],"preferred":true,"id":478241,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Tokita, Ken-ichi","contributorId":9150,"corporation":false,"usgs":true,"family":"Tokita","given":"Ken-ichi","email":"","affiliations":[],"preferred":false,"id":478244,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Shimada, Tetsuo","contributorId":52065,"corporation":false,"usgs":true,"family":"Shimada","given":"Tetsuo","email":"","affiliations":[],"preferred":false,"id":478246,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Ramey, Andrew M. 0000-0002-3601-8400 aramey@usgs.gov","orcid":"https://orcid.org/0000-0002-3601-8400","contributorId":1872,"corporation":false,"usgs":true,"family":"Ramey","given":"Andrew","email":"aramey@usgs.gov","middleInitial":"M.","affiliations":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true},{"id":117,"text":"Alaska Science Center Biology WTEB","active":true,"usgs":true}],"preferred":true,"id":478245,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Kharitonov, Sergei","contributorId":70672,"corporation":false,"usgs":true,"family":"Kharitonov","given":"Sergei","email":"","affiliations":[],"preferred":false,"id":478248,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Higuchi, Hiroyoshi","contributorId":69850,"corporation":false,"usgs":true,"family":"Higuchi","given":"Hiroyoshi","email":"","affiliations":[],"preferred":false,"id":478247,"contributorType":{"id":1,"text":"Authors"},"rank":9}]}}

Eyewitness accounts and new studies of deposit stratigraphy provide a combined narrative of eruptive events. Additional field, compositional, grain size, componentry, density, and grain morphology data document the influences on changing eruptive style as the eruption progressed. The eruption began on 1 May 1931 A.D. when a large subplinian eruption column produced vesicular juvenile-rich tephra. Subsequent activity was more intermittent, as magma interacted with groundwater and phreatomagmatic ash and lithic-rich tephra was dispersed up to 600 km downwind. Final erupted products were more mafic in composition and the eruption became more strombolian in style. Stratigraphic evidence suggests that two trachydacitic lava flows were erupted from separate but adjacent vents before the phreatomagmatic phase concluded and that basaltic andesite lava from a third vent began to effuse near the end of explosive activity. The estimated total bulk volume of the eruption is 0.9 km<sup>3</sup>, which corresponds to approximately 0.3 km<sup>3</sup> of magma. Eruption style changes are interpreted as follows: (1) a decrease in magma supply rate caused the change from subplinian to phreatomagmatic eruption; (2) a subsequent change in magma composition caused the transition from phreatomagmatic to strombolian eruption style. Additionally, the explosion and effusion of a similar magma composition from three separate vents indicates how the pre-existing caldera structure controlled the pathway of shallow magma ascent, thus influencing eruption style.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Volcanology and Geothermal Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","publisherLocation":"Amsterdam, Netherlands","doi":"10.1016/j.jvolgeores.2011.08.002","usgsCitation":"Nicholson, R.S., Gardner, J.E., and Neal, C., 2011, Variations in eruption style during the 1931 A.D. eruption of Aniakchak volcano, Alaska: Journal of Volcanology and Geothermal Research, v. 207, no. 3-4, p. 69-82, https://doi.org/10.1016/j.jvolgeores.2011.08.002.","productDescription":"14 p.","startPage":"69","endPage":"82","ipdsId":"IP-027583","costCenters":[{"id":121,"text":"Alaska Volcano Observatory","active":false,"usgs":true}],"links":[{"id":263697,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":263696,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.jvolgeores.2011.08.002"}],"country":"United States","state":"Alaska","otherGeospatial":"Aniakchak Volcano","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -158.342862,56.608331 ], [ -158.342862,57.105562 ], [ -157.161242,57.105562 ], [ -157.161242,56.608331 ], [ -158.342862,56.608331 ] ] ] } } ] }","volume":"207","issue":"3-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"50bfbb15e4b01744973f77c6","contributors":{"authors":[{"text":"Nicholson, Robert S. rnichol@usgs.gov","contributorId":2283,"corporation":false,"usgs":true,"family":"Nicholson","given":"Robert","email":"rnichol@usgs.gov","middleInitial":"S.","affiliations":[{"id":470,"text":"New Jersey Water Science Center","active":true,"usgs":true}],"preferred":true,"id":469653,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Gardner, James E.","contributorId":43243,"corporation":false,"usgs":true,"family":"Gardner","given":"James","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":469654,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Neal, Christina A. 0000-0002-7697-7825","orcid":"https://orcid.org/0000-0002-7697-7825","contributorId":82660,"corporation":false,"usgs":true,"family":"Neal","given":"Christina A.","affiliations":[],"preferred":false,"id":469655,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Because these species are highly migratory, there is concern that infected shorebirds may be a mechanism by which highly pathogenic avian influenza virus (HPAIV) H5N1 could be introduced into North America from Asia. Large numbers of dunlin (<i>Calidris alpina</i>) migrate from wintering areas in central and eastern Asia, where HPAIV H5N1 is endemic, across the Bering Sea to breeding areas in Alaska. Low pathogenic avian influenza virus has been previously detected in dunlin, and thus, dunlin represent a potential risk to transport HPAIV to North America. To date no experimental challenge studies have been performed in shorebirds.</p>\n<p><strong>Methods</strong> Wild dunlin were inoculated intranasally and intrachoanally various doses of HPAIV H5N1. The birds were monitored daily for virus excretion, disease signs, morbidity, and mortality.</p>\n<p><strong>Results</strong> The infectious dose of HPAIV H5N1 in dunlin was determined to be 10<sup>1.7</sup> EID<sub>50</sub>/100 &mu;l and that the lethal dose was 10<sup>1.83</sup> EID<sub>50</sub>/100 &mu;l. Clinical signs were consistent with neurotropic disease, and histochemical analyses revealed that infection was systemic with viral antigen and RNA most consistently found in brain tissues. Infected birds excreted relatively large amounts of virus orally (10<sup>4</sup> EID<sub>50</sub>) and smaller amounts cloacally.</p>\n<p><strong>Conclusions</strong> Dunlin are highly susceptible to infection with HPAIV H5N1. They become infected after exposure to relatively small doses of the virus and if they become infected, they are most likely to suffer mortality within 3&ndash;5 days. These results have important implications regarding the risks of transport and transmission of HPAIV H5N1 to North America by this species and raises questions for further investigation.</p>","language":"English","publisher":"Wiley","publisherLocation":"Hoboken, NJ","doi":"10.1111/j.1750-2659.2011.00238.x","usgsCitation":"Hall, J.S., Franson, J., Gill, R., Meteyer, C.U., TeSlaa, J.L., Nashold, S.W., Dusek, R., and Ip, S., 2011, Experimental challenge and pathology of highly pathogenic avian influenza virus H5N1 in dunlin (<i>Calidris alpina</i>), an intercontinental migrant shorebird species: Influenza and Other Respiratory Viruses, v. 5, no. 5, p. 365-372, https://doi.org/10.1111/j.1750-2659.2011.00238.x.","productDescription":"8 p.","startPage":"365","endPage":"372","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true},{"id":456,"text":"National Wildlife Health Center","active":true,"usgs":true}],"links":[{"id":474724,"rank":1,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://doi.org/10.1111/j.1750-2659.2011.00238.x","text":"External Repository"},{"id":257821,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","otherGeospatial":"Yukon-Kuskokwim Delta","volume":"5","issue":"5","noUsgsAuthors":false,"publicationDate":"2011-03-15","publicationStatus":"PW","scienceBaseUri":"505a0dc3e4b0c8380cd531a0","contributors":{"authors":[{"text":"Hall, Jeffrey S. 0000-0001-5599-2826 jshall@usgs.gov","orcid":"https://orcid.org/0000-0001-5599-2826","contributorId":2254,"corporation":false,"usgs":true,"family":"Hall","given":"Jeffrey","email":"jshall@usgs.gov","middleInitial":"S.","affiliations":[{"id":456,"text":"National Wildlife Health Center","active":true,"usgs":true}],"preferred":true,"id":353222,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Franson, J.

In this paper we present the first comprehensive synthesis of climate-change impacts on all forested ecosystems of Alaska, highlighting changes in the most critical biophysical factors of each region. We developed a conceptual framework describing climate drivers, biophysical factors and types of change to illustrate how the biophysical and social subsystems of Alaskan forests interact and respond directly and indirectly to a changing climate. We then identify the regional and global implications to the climate system and associated socio-economic impacts, as presented in the current literature. Projections of temperature and precipitation suggest wildfire will continue to be the dominant biophysical factor in the Interior-boreal forest, leading to shifts from conifer- to deciduous-dominated forests. Based on existing research, projected increases in temperature in the Southcentral- and Kenai-boreal forests will likely increase the frequency and severity of insect outbreaks and associated wildfires, and increase the probability of establishment by invasive plant species. In the Coastal-temperate forest region snow and ice is regarded as the dominant biophysical factor. With continued warming, hydrologic changes related to more rapidly melting glaciers and rising elevation of the winter snowline will alter discharge in many rivers, which will have important consequences for terrestrial and marine ecosystem productivity. These climate-related changes will affect plant species distribution and wildlife habitat, which have regional societal consequences, and trace-gas emissions and radiation budgets, which are globally important. Our conceptual framework facilitates assessment of current and future consequences of a changing climate, emphasizes regional differences in biophysical factors, and points to linkages that may exist but that currently lack supporting research. The framework also serves as a visual tool for resource managers and policy makers to develop regional and global management strategies and to inform policies related to climate mitigation and adaptation.</p>","language":"English","publisher":"Ecological Society of America","publisherLocation":"Ithaca, NY","doi":"10.1890/ES11-00288.1","usgsCitation":"Wolken, J.M., Hollingsworth, T.N., Rupp, T., Chapin, S., Trainor, S., Barrett, T.M., Sullivan, P.F., McGuire, A., Euskirchen, E., Hennon, P.E., Beever, E.A., Conn, J.S., Crone, L.K., D’Amore, D.V., Fresco, N., Hanley, T.A., Kielland, K., Kruse, J.J., Patterson, T., Schuur, E.A., Verbyla, D.L., and Yarie, J., 2011, Evidence and implications of recent and projected climate change in Alaska's forest ecosystems: Ecosphere, v. 2, no. 11, p. 1-35, https://doi.org/10.1890/ES11-00288.1.","productDescription":"Article 124; 35 p.","startPage":"1","endPage":"35","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-028623","costCenters":[{"id":481,"text":"Northern Rocky Mountain Science Center","active":true,"usgs":true}],"links":[{"id":474728,"rank":2,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1890/es11-00288.1","text":"Publisher Index Page"},{"id":257817,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","volume":"2","issue":"11","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a0d28e4b0c8380cd52e43","contributors":{"authors":[{"text":"Wolken, Jane M.","contributorId":35168,"corporation":false,"usgs":true,"family":"Wolken","given":"Jane","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":349750,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hollingsworth, Teresa N.","contributorId":19016,"corporation":false,"usgs":true,"family":"Hollingsworth","given":"Teresa","email":"","middleInitial":"N.","affiliations":[],"preferred":false,"id":349743,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Rupp, T.

The DMTS haul road is the transport corridor between Red Dog Mine (a large-scale, lead-zinc mine and mill) and the coastal shipping port, and it traverses National Park Service lands. Compared to reference locations, total metal concentrations in four types of vegetation (birch, cranberry, and willow leaves, and cotton grass blades/stalks) collected 25 m from the haul road were enriched on average by factors of 3.5 for zinc, 8.0 for barium, 20 for cadmium, and 150 for lead. Triple rinsing of vegetation with a water/methanol mixture reduced metals concentrations by at most 50%, and cadmium and zinc concentrations were least affected by rinsing. Cadmium and zinc bioaccessibility was greater in vegetation (50% to 100%) than in dust (15% to 20%); whereas the opposite pattern was observed for lead bioaccessibility (<30% in vegetation; 50% in dust). Barium exhibited low-to-intermediate bioaccessibility in dust and vegetation (20% to 40%), whereas aluminum bioaccessibility was relatively low (<6%) in all sample types. Our reconnaissance-level study indicates that clean-up and improvements in lead/zinc concentrate transfer activities have been effective; however, as of 2006, metal dispersion from past and/or present releases of fugitive dusts along the DMTS road still may have been contributing to elevated metals in surface vegetation. Vegetation was most enriched in lead, but because bioaccessibility of cadmium was greater, any potential risks to animals that forage near the haul road might be equally important for both of these metals.","language":"English","publisher":"Springer","doi":"10.1007/s10661-011-1879-z","usgsCitation":"Brumbaugh, W.G., Morman, S.A., and May, T.W., 2011, Concentrations and bioaccessibility of metals in vegetation and dust near a mining haul road, Cape Krusenstern National Monument, Alaska: Environmental Monitoring and Assessment, v. 182, no. 1-4, p. 325-340, https://doi.org/10.1007/s10661-011-1879-z.","productDescription":"16 p.","startPage":"325","endPage":"340","numberOfPages":"16","costCenters":[{"id":192,"text":"Columbia Environmental Research Center","active":true,"usgs":true},{"id":34983,"text":"Contaminant Biology Program","active":true,"usgs":true}],"links":[{"id":257599,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","otherGeospatial":"Cape Krusenstern National Monument","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -164.90478515625,\n              67.01171909603052\n            ],\n            [\n              -161.839599609375,\n              67.01171909603052\n            ],\n            [\n              -161.839599609375,\n              67.83412789868609\n            ],\n            [\n              -164.90478515625,\n              67.83412789868609\n            ],\n            [\n              -164.90478515625,\n              67.01171909603052\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"182","issue":"1-4","noUsgsAuthors":false,"publicationDate":"2011-02-12","publicationStatus":"PW","scienceBaseUri":"5059f983e4b0c8380cd4d64c","contributors":{"authors":[{"text":"Brumbaugh, William G. 0000-0003-0081-375X bbrumbaugh@usgs.gov","orcid":"https://orcid.org/0000-0003-0081-375X","contributorId":493,"corporation":false,"usgs":true,"family":"Brumbaugh","given":"William","email":"bbrumbaugh@usgs.gov","middleInitial":"G.","affiliations":[{"id":192,"text":"Columbia Environmental Research Center","active":true,"usgs":true}],"preferred":true,"id":350009,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Morman, Suzette A. 0000-0002-2532-1033 smorman@usgs.gov","orcid":"https://orcid.org/0000-0002-2532-1033","contributorId":996,"corporation":false,"usgs":true,"family":"Morman","given":"Suzette","email":"smorman@usgs.gov","middleInitial":"A.","affiliations":[{"id":171,"text":"Central Mineral and Environmental Resources Science Center","active":true,"usgs":true},{"id":211,"text":"Crustal Geophysics and Geochemistry Science Center","active":true,"usgs":true}],"preferred":true,"id":350010,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"May, Thomas W. tmay@usgs.gov","contributorId":2598,"corporation":false,"usgs":true,"family":"May","given":"Thomas","email":"tmay@usgs.gov","middleInitial":"W.","affiliations":[{"id":192,"text":"Columbia Environmental Research Center","active":true,"usgs":true}],"preferred":false,"id":350011,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Results of surveys and monitoring will be informative for resource managers and will be useful for studying potential changes in ecological communities of the high latitudes. We estimated that the probability of detecting a Gyrfalcon at an occupied nest site was between 64% and 87% depending on observer experience and aircraft type (fixed-wing or helicopter). The probability of detection is an important factor for estimating occupancy of nesting areas, and occupancy can be used as a metric for monitoring species' status. We conclude that surveys of nesting habitat to monitor occupancy during the breeding season are practical because of the high probability of seeing a Gyrfalcon from aircraft. Aerial surveys are effective for searching sample plots or index areas in the expanse of the Alaskan terrain. Furthermore, several species of cliff-nesting birds can be surveyed concurrently from aircraft. Occupancy estimation also can be applied using data from other field search methods (e.g., from boats) that have proven useful in Alaska. We believe a coordinated broad-scale, inter-agency, collaborative approach is necessary in Alaska. Monitoring can be facilitated by collating and archiving each set of results in a secure universal repository to allow for statewide meta-analysis.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Gyrfalcons and Ptarmigan in a Changing World","largerWorkSubtype":{"id":12,"text":"Conference publication"},"conferenceTitle":"Gyrfalcons and Ptarmigan in a Changing World","conferenceDate":"February 1-3, 2011","conferenceLocation":"Boise, Idaho","language":"English","publisher":"The Peregrine Fund","publisherLocation":"Boise, ID","usgsCitation":"Fuller, M.R., Schempf, P.F., and Booms, T.L., 2011, Developing Gyrfalcon surveys and monitoring for Alaska, <i>in</i> Gyrfalcons and Ptarmigan in a Changing World, Boise, Idaho, February 1-3, 2011, p. 275-282.","productDescription":"8 p.","startPage":"275","endPage":"282","costCenters":[{"id":290,"text":"Forest and Rangeland Ecosystem Science Center","active":false,"usgs":true}],"links":[{"id":257104,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":257099,"rank":300,"type":{"id":15,"text":"Index Page"},"url":"https://www.peregrinefund.org/subsites/conference-gyr/proceedings/","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"Alaska","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a0007e4b0c8380cd4f547","contributors":{"authors":[{"text":"Fuller, Mark R. 0000-0001-7459-1729 mark_fuller@usgs.gov","orcid":"https://orcid.org/0000-0001-7459-1729","contributorId":2296,"corporation":false,"usgs":true,"family":"Fuller","given":"Mark","email":"mark_fuller@usgs.gov","middleInitial":"R.","affiliations":[{"id":290,"text":"Forest and Rangeland Ecosystem Science Center","active":false,"usgs":true},{"id":289,"text":"Forest and Rangeland Ecosys Science Center","active":true,"usgs":true}],"preferred":true,"id":356040,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Schempf, Philip F.","contributorId":36795,"corporation":false,"usgs":true,"family":"Schempf","given":"Philip","email":"","middleInitial":"F.","affiliations":[],"preferred":false,"id":356041,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Booms, Travis L.","contributorId":48813,"corporation":false,"usgs":true,"family":"Booms","given":"Travis","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":356042,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Exports of Hg averaged 4400 kg Hg yr<sup>-1</sup>. The average annual yield for the YRB during the study period was 5.17 &mu;g m<sup>-2</sup> yr<sup>-1</sup>, which is 3&ndash;32 times more than Hg yields reported for 8 other major northern hemisphere river basins. The vast majority (90%) of Hg export is associated with particulates. Half of the annual export of Hg occurred during the spring with about 80% of 34 samples exceeding the U.S. EPA Hg standard for adverse chronic effects to biota. Dissolved and particulate organic carbon exports explained 81% and 50%, respectively, of the variance in Hg exports, and both were significantly (<i>p</i> < 0.001) correlated with water discharge. Recent measurements indicate that permafrost contains a substantial reservoir of Hg. Consequently, climate warming will likely accelerate the mobilization of Hg from thawing permafrost increasing the export of organic carbon associated Hg and thus potentially exacerbating the production of bioavailable methylmercury from permafrost-dominated northern river basins.","language":"English","publisher":"ACS Publications","doi":"10.1021/es202068b","usgsCitation":"Schuster, P.F., Striegl, R.G., Aiken, G.R., Krabbenhoft, D.P., DeWild, J.F., Butler, K.D., Kamark, B., and Dornblaser, M., 2011, Mercury export from the Yukon River Basin and potential response to a changing climate: Environmental Science & Technology, v. 45, no. 21, p. 9262-9267, https://doi.org/10.1021/es202068b.","productDescription":"6 p.","startPage":"9262","endPage":"9267","numberOfPages":"6","costCenters":[{"id":145,"text":"Branch of Regional Research-Central Region","active":false,"usgs":true},{"id":381,"text":"Mercury Research Laboratory","active":false,"usgs":true},{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":257222,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","otherGeospatial":"Yukon River Basin","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -155.21484375,\n              61.71070595883174\n            ],\n            [\n              -141.15234374999997,\n              61.71070595883174\n            ],\n            [\n              -141.15234374999997,\n              69.19379976461904\n            ],\n            [\n              -155.21484375,\n              69.19379976461904\n            ],\n            [\n              -155.21484375,\n              61.71070595883174\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"45","issue":"21","noUsgsAuthors":false,"publicationDate":"2011-10-06","publicationStatus":"PW","scienceBaseUri":"505a5403e4b0c8380cd6ce63","contributors":{"authors":[{"text":"Schuster, Paul F. 0000-0002-8314-1372 pschuste@usgs.gov","orcid":"https://orcid.org/0000-0002-8314-1372","contributorId":1360,"corporation":false,"usgs":true,"family":"Schuster","given":"Paul","email":"pschuste@usgs.gov","middleInitial":"F.","affiliations":[{"id":5044,"text":"National Research Program -

The accompanying surficial geologic map covers all of the GAAR with the addition of a 10-km (6.2-mi) belt or \"buffer zone\" beyond its boundaries. A narrower (5-km) buffer zone is employed where the GAAR extends farthest north and south of the Brooks Range, in the north-central and southwestern parts of the map area, respectively.</p>\n<p>The surfical geologic map incorporates parts of ten surficial geologic maps previously published at 1:250,000 scale. In addition, a small part of the buffer zone mapped in the southwest corner of the map area was compiled from unpublished surficial geologic mapping of the Shungnak 1:250,000-scale quadrangle. Each of those individual maps was developed from (1) aerial and surface observations of morphology and composition of unconsolidated deposits, (2) tracing the distribution and interrelation of terraces, abandoned meltwater channels, moraines, abandoned lake beds, and other landforms, (3) stratigraphic study of exposures along lake shores and river bluffs, (4) examination of sediments and soil profiles in auger borings and test pits, and exposed in roadcuts and placer workings, and (5) analysis of previously published geologic maps and reports. The map units used for those maps and employed in the present compilation are defined on the basis of their physical character, genesis, and age. Relative and absolute ages of the map units were determined from their geographic locations and from their stratigraphic positions and radiocarbon ages.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/sim3125","usgsCitation":"Hamilton, T.D., and Labay, K., 2011, Surficial geologic map of the Gates of the Arctic National Park and Preserve, Alaska: U.S. Geological Survey Scientific Investigations Map 3125, Pamphlet: ii, 19 p.; Map Sheet: 55.70 x 39.02 inches, https://doi.org/10.3133/sim3125.","productDescription":"Pamphlet: ii, 19 p.; Map Sheet: 55.70 x 39.02 inches","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"links":[{"id":246788,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/sim_3125.gif"},{"id":246786,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/sim/3125/","linkFileType":{"id":5,"text":"html"}}],"scale":"300000","projection":"Alaska Albers Equal Area Conic projection","datum":"North American Datum 1927","country":"United States","state":"Alaska","otherGeospatial":"Gates Of The Arctic National Park And Preserve","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -157.25,68.75 ], [ -157.25,66.58333333333333 ], [ -149.25,66.58333333333333 ], [ -149.25,68.75 ], [ -157.25,68.75 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505ba1f7e4b08c986b31f409","contributors":{"authors":[{"text":"Hamilton, Thomas D.","contributorId":91474,"corporation":false,"usgs":true,"family":"Hamilton","given":"Thomas","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":462896,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Labay, Keith A. 0000-0002-6763-3190 klabay@usgs.gov","orcid":"https://orcid.org/0000-0002-6763-3190","contributorId":2097,"corporation":false,"usgs":true,"family":"Labay","given":"Keith A.","email":"klabay@usgs.gov","affiliations":[{"id":119,"text":"Alaska Science Center Geology Minerals","active":true,"usgs":true}],"preferred":false,"id":462897,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

In 2005, an unprecedented epizootic at Qinghai Lake killed more than 6000 migratory birds including over 3000 bar-headed geese (<i>Anser indicus</i>). H5N1 subsequently spread to Europe and Africa, and in following years has re-emerged in wild birds along the Central Asia flyway several times.</p>\n<p><b>Methodology/Principal Findings</b></p>\n<p>To better understand the potential involvement of wild birds in the spread of H5N1, we studied the movements of bar-headed geese marked with GPS satellite transmitters at Qinghai Lake in relation to virus outbreaks and disease risk factors. We discovered a previously undocumented migratory pathway between Qinghai Lake and the Lhasa Valley of Tibet where 93% of the 29 marked geese overwintered. From 2003&ndash;2009, sixteen outbreaks in poultry or wild birds were confirmed on the Qinghai-Tibet Plateau, and the majority were located within the migratory pathway of the geese. Spatial and temporal concordance between goose movements and three potential H5N1 virus sources (poultry farms, a captive bar-headed goose facility, and H5N1 outbreak locations) indicated ample opportunities existed for virus spillover and infection of migratory geese on the wintering grounds. Their potential as a vector of H5N1 was supported by rapid migration movements of some geese and genetic relatedness of H5N1 virus isolated from geese in Tibet and Qinghai Lake.</p>\n<p><b>Conclusions/Significance</b></p>\n<p>This is the first study to compare phylogenetics of the virus with spatial ecology of its host, and the combined results suggest that wild birds play a role in the spread of H5N1 in this region. However, the strength of the evidence would be improved with additional sequences from both poultry and wild birds on the Qinghai-Tibet Plateau where H5N1 has a clear

As part of a U.S. Geological Survey (USGS) and Bureau of Land Management gas hydrate research collaboration, well-cutting and mud-gas samples have been collected and analyzed from mainly industry-drilled wells on the North Slope for the purpose of prospecting for gas hydrate deposits. On the Alaska North Slope, gas hydrates are now recognized as an element within a petroleum systems approach or \"total petroleum system.\" Since 1979, 35 wells have been sampled from as far west as Wainwright to Prudhoe Bay in the east. Regionally, the USGS has assessed the gas hydrate resources of the North Slope and determined that there is about 85.4 trillion cubic feet of technically recoverable hydrate-bound gas within three assessment units. The assessment units are defined mainly by three separate stratigraphic sections and constrained by the physical temperatures and pressures where gas hydrate can form. Geochemical studies of known gas hydrate occurrences on the North Slope have shown a link between gas hydrate and more deeply buried conventional oil and gas deposits. The link is established when hydrocarbon gases migrate from depth and charge the reservoir rock within the gas hydrate stability zone. It is likely gases migrated into conventional traps as free gas and were later converted to gas hydrate in response to climate cooling concurrent with permafrost formation. Results from this study indicate that some thermogenic gas is present in 31 of the wells, with limited evidence of thermogenic gas in four other wells and only one well with no thermogenic gas. Gas hydrate is known to occur in one of the sampled wells, likely present in 22 others on the basis of gas geochemistry, and inferred by equivocal gas geochemistry in 11 wells, and one well was without gas hydrate. Gas migration routes are common in the North Slope and include faults and widespread, continuous shallowly dipping permeable sand sections that are potentially in communication with deeper oil and gas sources. The application of the petroleum system model with the geochemical evidence suggests that gas hydrate deposits may be widespread across the North Slope of Alaska.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/sir20115195","usgsCitation":"Lorenson, T., and Collett, T.S., 2011, Gas hydrate prospecting using well cuttings and mud-gas geochemistry from 35 wells, North Slope, Alaska: U.S. Geological Survey Scientific Investigations Report 2011-5195, iv, 25 p.; Appendices; Appendix 2 download; Appendix 3 download; Appendix 4 download, https://doi.org/10.3133/sir20115195.","productDescription":"iv, 25 p.; Appendices; Appendix 2 download; Appendix 3 download; Appendix 4 download","additionalOnlineFiles":"Y","costCenters":[{"id":164,"text":"Central Energy Resources Science Center","active":true,"usgs":true}],"links":[{"id":116461,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/sir_2011_5195.gif"},{"id":115783,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/sir/2011/5195/","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"Alaska","otherGeospatial":"North Slope","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -162,69.5 ], [ -162,71.25 ], [ -144,71.25 ], [ -144,69.5 ], [ -162,69.5 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a14cfe4b0c8380cd54b93","contributors":{"authors":[{"text":"Lorenson, T.D. tlorenson@usgs.gov","contributorId":2622,"corporation":false,"usgs":true,"family":"Lorenson","given":"T.D.","email":"tlorenson@usgs.gov","affiliations":[{"id":186,"text":"Coastal and Marine Geology Program","active":true,"usgs":true}],"preferred":false,"id":356266,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Collett, Timothy S. 0000-0002-7598-4708 tcollett@usgs.gov","orcid":"https://orcid.org/0000-0002-7598-4708","contributorId":1698,"corporation":false,"usgs":true,"family":"Collett","given":"Timothy","email":"tcollett@usgs.gov","middleInitial":"S.","affiliations":[{"id":678,"text":"Woods Hole Coastal and Marine Science Center","active":true,"usgs":true},{"id":171,"text":"Central Mineral and Environmental Resources Science Center","active":true,"usgs":true},{"id":255,"text":"Energy Resources Program","active":true,"usgs":true},{"id":164,"text":"Central Energy Resources Science Center","active":true,"usgs":true}],"preferred":true,"id":356265,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Two hypotheses explained this redistribution: (1) ecological change: redistribution of molting brant reflects improvements in coastal foraging habitats, which have undergone a succession toward salt-tolerant plants due to increased coastal erosion and saltwater intrusion as induced by climate change or (2) interspecific competition: greater white-fronted geese (<i>Anser albifrons</i>) populations increased 12-fold at inland lakes, limiting food availability and forcing brant into coastal habitats. Both hypotheses presume that brant redistributions were driven by food availability; thus, body mass dynamics may provide insight into the relevance of these hypotheses. We compared body mass dynamics of molting brant across decades (1978, 1987&ndash;1992, 2005&ndash;2007) and, during 2005&ndash;2007, across habitats (coastal vs. inland). Brant lost body mass during molt in all three decades. At inland habitats, rates of mass loss progressively decreased by decade despite the increased number of greater white-fronted geese. These results do not support an interspecific competition hypothesis, instead suggesting that ecological change enhanced foraging habitats for brant. During 2005&ndash;2007, rates of mass loss did not vary by habitat. Thus, while habitats have improved from earlier decades, our results cannot distinguish between ecological changes at inland versus coastal habitats. However, we speculate that coastal forage quality has improved beyond that of inland habitats and that the body mass benefits of these higher quality foods are offset by the disproportionate number of brant now molting coastally.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Polar Biology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Springer","publisherLocation":"Amsterdam, Netherlands","doi":"10.1007/s00300-011-1025-y","usgsCitation":"Lewis, T., Flint, P.L., Derksen, D.V., Schmutz, J.A., Taylor, E., and Bollinger, K.S., 2011, Using body mass dynamics to examine long-term habitat shifts of arctic-molting geese: Evidence for ecological change: Polar Biology, v. 34, no. 11, p. 1751-1762, https://doi.org/10.1007/s00300-011-1025-y.","productDescription":"12 p.","startPage":"1751","endPage":"1762","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"links":[{"id":115756,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://dx.doi.org/10.1007/s00300-011-1025-y","linkFileType":{"id":5,"text":"html"}},{"id":204616,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","otherGeospatial":"Teshekpuk Lake Special Area","volume":"34","issue":"11","noUsgsAuthors":false,"publicationDate":"2011-05-05","publicationStatus":"PW","scienceBaseUri":"505bc037e4b08c986b329fbe","contributors":{"authors":[{"text":"Lewis, Tyler L.","contributorId":22904,"corporation":false,"usgs":false,"family":"Lewis","given":"Tyler L.","affiliations":[{"id":12437,"text":"Simon Fraser University, Centre for Wildlife Ecology","active":true,"usgs":false}],"preferred":false,"id":347608,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Flint, Paul L. 0000-0002-8758-6993 pflint@usgs.gov","orcid":"https://orcid.org/0000-0002-8758-6993","contributorId":3284,"corporation":false,"usgs":true,"family":"Flint","given":"Paul","email":"pflint@usgs.gov","middleInitial":"L.","affiliations":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true},{"id":117,"text":"Alaska Science Center Biology WTEB","active":true,"usgs":true}],"preferred":true,"id":347607,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Derksen, Dirk V. dderksen@usgs.gov","contributorId":2269,"corporation":false,"usgs":true,"family":"Derksen","given":"Dirk","email":"dderksen@usgs.gov","middleInitial":"V.","affiliations":[{"id":117,"text":"Alaska Science Center Biology WTEB","active":true,"usgs":true}],"preferred":true,"id":347606,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Schmutz, Joel A. 0000-0002-6516-0836 jschmutz@usgs.gov","orcid":"https://orcid.org/0000-0002-6516-0836","contributorId":1805,"corporation":false,"usgs":true,"family":"Schmutz","given":"Joel","email":"jschmutz@usgs.gov","middleInitial":"A.","affiliations":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true},{"id":117,"text":"Alaska Science Center Biology WTEB","active":true,"usgs":true}],"preferred":true,"id":347605,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Taylor, Eric J.","contributorId":41966,"corporation":false,"usgs":false,"family":"Taylor","given":"Eric J.","affiliations":[{"id":6661,"text":"US Fish and Wildlife Service","active":true,"usgs":false}],"preferred":false,"id":347610,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Bollinger, Karen S.","contributorId":33842,"corporation":false,"usgs":true,"family":"Bollinger","given":"Karen","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":347609,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

With the support and cooperation of visionaries, financiers, scientists, and other individuals and organizations, HVO has successfully achieved 100 years of continuous monitoring of Hawaiian volcanoes. As we celebrate this milestone anniversary, we express our sincere mahalo&mdash;thanks&mdash;to the people who have contributed to and participated in HVO&rsquo;s mission during this past century. First and foremost, we owe a debt of gratitude to the late Thomas A. Jaggar, Jr., the geologist whose vision and efforts led to the founding of HVO. We also acknowledge the pioneering contributions of the late Frank A. Perret, who began the continuous monitoring of K&#299;lauea in 1911, setting the stage for Jaggar, who took over the work in 1912. Initial support for HVO was provided by the Massachusetts Institute of Technology (MIT) and the Carnegie Geophysical Laboratory, which financed the initial cache of volcano monitoring instruments and Perret&rsquo;s work in 1911. The Hawaiian Volcano Research Association, a group of Honolulu businessmen organized by Lorrin A. Thurston, also provided essential funding for HVO&rsquo;s daily operations starting in mid-1912 and continuing for several decades. Since HVO&rsquo;s beginning, the University of Hawai&#699;i (UH), called the College of Hawaii until 1920, has been an advocate of HVO&rsquo;s scientific studies. We have benefited from collaborations with UH scientists at both the Hilo and M&#228;noa campuses and look forward to future cooperative efforts to better understand how Hawaiian volcanoes work. The U.S. Geological Survey (USGS) has operated HVO continuously since 1947. Before then, HVO was under the administration of various Federal agencies&mdash;the U.S. Weather Bureau, at the time part of the Department of Agriculture, from 1919 to 1924; the USGS, which first managed HVO from 1924 to 1935; and the National Park Service from 1935 to 1947. For 76 of its first 100 years, HVO has been part of the USGS, the Nation&rsquo;s premier Earth science agency. It currently operates under the direction of the USGS Volcano Science Center, which now supports five volcano observatories covering six U.S. areas&mdash;Hawai&#699;i (HVO), Alaska and the Northern Mariana Islands (Alaska Volcano Observatory), Washington and Oregon (Cascades Volcano Observatory), California (California Volcano Observatory), and the Yellowstone region (Yellowstone Volcano Observatory). Although the National Park Service (NPS) managed HVO for only 12 years, HVO has enjoyed a close working relationship with Hawai&#699;i Volcanoes National Park (named Hawaii National Park until 1961) since the park&rsquo;s founding in 1916. Today, as in past years, the USGS and NPS work together to ensure the safety and education of park visitors. We are grateful to all park employees, particularly Superintendent Cindy Orlando and Chief Ranger Talmadge Magno and their predecessors, for their continuing support of HVO&rsquo;s mission. HVO also works closely with the Hawai&#699;i County Civil Defense. During volcanic and earthquake crises, we have appreciated the support of civil defense staff, especially that of Harry Kim and Quince Mento, who administered the agency during highly stressful episodes of K&#299;lauea's ongoing eruption. Our work in remote areas on Hawai&#699;i&rsquo;s active volcanoes is possible only with the able assistance of Hawai&#699;i County and private pilots who have safely flown HVO staff to eruption sites through the decades. A special mahalo goes to David Okita, who has been HVO&rsquo;s principal helicopter pilot for more than two decades. Many commercial and Civil Air Patrol pilots have also assisted HVO by reporting their observations during various eruptive events. Hawai&#699;i&rsquo;s news media&mdash;print, television, radio, and online sources&mdash;do an excellent job of distributing volcano and earthquake information to the public. Their assistance is invaluable to HVO, especially during times of crisis. HVO&rsquo;s efforts to provide timely and accurate scientific information about Hawaiian volcanoes and earthquakes succeed only because of you, our receptive and keenly aware public. By following the activity of Hawai&#699;i&rsquo;s active volcanoes through our daily eruption updates posted on the HVO website, viewing HVO webcam images, reading our weekly &ldquo;Volcano Watch&rdquo; articles, and attending our public lectures, you help us to ensure that you can live safely with Hawai&#699;i&rsquo;s dynamic volcanoes. To everyone who has shared in HVO&rsquo;s reaching this milestone&mdash;100 years of continuous volcano monitoring&mdash;we extend our deepest gratitude. <i>Mahalo nui loa!</i>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/gip135","usgsCitation":"Babb, J., Kauahikaua, J.P., and Tilling, R.I., 2011, The story of the Hawaiian Volcano Observatory -- A remarkable first 100 years of tracking eruptions and earthquakes: U.S. Geological Survey General Information Product 135, vi, 63 p; PDF Downloads of Report in standard resolution, for printing, and for ebooks and tablets, https://doi.org/10.3133/gip135.","productDescription":"vi, 63 p; PDF Downloads of Report in standard resolution, for printing, and for ebooks and tablets","startPage":"i","endPage":"63","numberOfPages":"69","onlineOnly":"N","additionalOnlineFiles":"Y","temporalStart":"1912-01-01","temporalEnd":"2012-12-31","costCenters":[{"id":336,"text":"Hawaiian Volcano Observatory","active":false,"usgs":true},{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"links":[{"id":116699,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/gip_135.gif"},{"id":112500,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/gip/135/","linkFileType":{"id":5,"text":"html"}}],"scale":"85342","country":"United States","state":"Hawai'i","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -161,18 ], [ -161,23 ], [ -154,23 ], [ -154,18 ], [ -161,18 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bb07de4b08c986b324ebd","contributors":{"authors":[{"text":"Babb, Janet L.","contributorId":89659,"corporation":false,"usgs":true,"family":"Babb","given":"Janet L.","affiliations":[],"preferred":false,"id":355915,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kauahikaua, James P. 0000-0003-3777-503X jimk@usgs.gov","orcid":"https://orcid.org/0000-0003-3777-503X","contributorId":2146,"corporation":false,"usgs":true,"family":"Kauahikaua","given":"James","email":"jimk@usgs.gov","middleInitial":"P.","affiliations":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"preferred":true,"id":355913,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Tilling, Robert I. 0000-0003-4263-7221 rtilling@usgs.gov","orcid":"https://orcid.org/0000-0003-4263-7221","contributorId":2567,"corporation":false,"usgs":true,"family":"Tilling","given":"Robert","email":"rtilling@usgs.gov","middleInitial":"I.","affiliations":[],"preferred":true,"id":355914,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Following the spill, extensive efforts have been directed toward identifying and understanding long-term consequences of the spill and the process of recovery. We conducted annual aerial surveys of sea otter abundance from 1993 to 2009 (except for 2001 and 2006) in WPWS. We observed an increasing trend in population abundance at the scale of WPWS through 2000 at an average annual rate of 4 percent: however, at northern Knight Island where oiling was heaviest and sea otter mortality highest, no increase in abundance was evident by 2000. We continued to see significant increase in abundance at the scale of WPWS between 2001 and 2009, with an average annual rate of increase from 1993 to 2009 of 2.6 percent. We estimated the 2009 population size of WPWS to be 3,958 animals (standard error=653), nearly 2,000 animals more than the first post-spill estimate in 1993. Surveys since 2003 also have identified a significant increasing trend at the heavily oiled site in northern Knight Island, averaging about 25 percent annually and resulting in a 2009 estimated population size of 116 animals (standard error=19). Although the 2009 estimate for northern Knight Island remains about 30 percent less than the pre-spill estimate of 165 animals, we interpret this trend as strong evidence of a trajectory toward recovery of spill-affected sea otter populations in WPWS.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/sir20115213","usgsCitation":"Bodkin, J.L., Ballachey, B.E., and Esslinger, G.G., 2011, Trends in sea otter population abundance in western Prince William Sound, Alaska: Progress toward recovery following the 1989 Exxon Valdez oil spill: U.S. Geological Survey Scientific Investigations Report 2011-5213, iv, 14 p., https://doi.org/10.3133/sir20115213.","productDescription":"iv, 14 p.","startPage":"i","endPage":"14","numberOfPages":"18","additionalOnlineFiles":"N","temporalStart":"1993-01-01","temporalEnd":"2009-12-31","ipdsId":"IP-018393","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"links":[{"id":116339,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/sir_2011_5213.png"},{"id":112425,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/sir/2011/5213/","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"Alaska","otherGeospatial":"Prince William Sound","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bb800e4b08c986b3275f5","contributors":{"authors":[{"text":"Bodkin, James L. 0000-0003-1641-4438 jbodkin@usgs.gov","orcid":"https://orcid.org/0000-0003-1641-4438","contributorId":748,"corporation":false,"usgs":true,"family":"Bodkin","given":"James","email":"jbodkin@usgs.gov","middleInitial":"L.","affiliations":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true},{"id":116,"text":"Alaska Science Center Biology MFEB","active":true,"usgs":true}],"preferred":true,"id":355780,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Ballachey, Brenda E. 0000-0003-1855-9171 bballachey@usgs.gov","orcid":"https://orcid.org/0000-0003-1855-9171","contributorId":2966,"corporation":false,"usgs":true,"family":"Ballachey","given":"Brenda","email":"bballachey@usgs.gov","middleInitial":"E.","affiliations":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true},{"id":116,"text":"Alaska Science Center Biology MFEB","active":true,"usgs":true}],"preferred":true,"id":355781,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Esslinger, George G. 0000-0002-3459-0083 gesslinger@usgs.gov","orcid":"https://orcid.org/0000-0002-3459-0083","contributorId":131009,"corporation":false,"usgs":true,"family":"Esslinger","given":"George","email":"gesslinger@usgs.gov","middleInitial":"G.","affiliations":[{"id":116,"text":"Alaska Science Center Biology MFEB","active":true,"usgs":true}],"preferred":true,"id":355782,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Because strong sea ice prevents large ocean waves from forming, sea ice can therefore significantly affect microseism amplitudes. Here we show that this link between sea ice and microseism is not only a robust one but can be quantified. In particular, we show that 75&ndash;90% of the variability in microseism power in the Bering Sea can be predicted using a fairly crude model of microseism damping by sea ice. The success of this simple parameterization suggests that an even stronger link can be established between the mechanical strength of sea ice and microseism power, and that microseism can eventually be used to monitor the strength of sea ice, a quantity that is not as easily observed through other means.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Geophysical Research Letters","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"American Geophysical Union","publisherLocation":"Washington, D.C.","doi":"10.1029/2011GL049791","usgsCitation":"Tsai, V., and McNamara, D.E., 2011, Quantifying the influence of sea ice on ocean microseism using observations from the Bering Sea, Alaska: Geophysical Research Letters, v. 38, 5 p.; L22502, https://doi.org/10.1029/2011GL049791.","productDescription":"5 p.; L22502","costCenters":[{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true}],"links":[{"id":474800,"rank":10000,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://resolver.caltech.edu/CaltechAUTHORS:20120105-135036867","text":"External Repository"},{"id":257176,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":257167,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1029/2011GL049791","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"Alaska","otherGeospatial":"Bering Sea","volume":"38","noUsgsAuthors":false,"publicationDate":"2011-11-19","publicationStatus":"PW","scienceBaseUri":"505a91e9e4b0c8380cd80532","contributors":{"authors":[{"text":"Tsai, Victor C. 0000-0003-1809-6672","orcid":"https://orcid.org/0000-0003-1809-6672","contributorId":87675,"corporation":false,"usgs":true,"family":"Tsai","given":"Victor C.","affiliations":[],"preferred":false,"id":350795,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"McNamara, Daniel E. 0000-0001-6860-0350 mcnamara@usgs.gov","orcid":"https://orcid.org/0000-0001-6860-0350","contributorId":402,"corporation":false,"usgs":true,"family":"McNamara","given":"Daniel","email":"mcnamara@usgs.gov","middleInitial":"E.","affiliations":[{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true}],"preferred":true,"id":350794,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

However, the greater magnitude of variations in the geomagnetic environment at higher latitudes makes the application of geomagnetic referencing in those areas more challenging. Precise, real-time data on those variations from relatively nearby magnetic observatories can be crucial to achieving the required accuracy, but constructing and operating an observatory in these often harsh environments poses a number of significant challenges. Operational since March 2010, the Deadhorse Magnetic Observatory (DED), located in Deadhorse, Alaska, was created through collaboration between the United States Geological Survey (USGS) and a leading oilfield services supply company. DED was designed to produce real-time geomagnetic data at the required level of accuracy, and to do so reliably under the extreme temperatures and harsh weather conditions often experienced in the area. The observatory will serve a number of key scientific communities as well as the oilfield drilling industry, and has already played a vital role in the success of several commercial ventures in the area, providing essential, accurate data while offering significant cost and time savings, compared with traditional surveying techniques.","conferenceTitle":"SPE Arctic and Extreme Environments Conference and Exhibition","conferenceLocation":"Moscow, Russia","language":"English","publisher":"Society of Petroleum Engineers","publisherLocation":"Allen, TX","doi":"10.2118/149629-MS","usgsCitation":"Podjono, B., Beck, N., Buchanan, A., Brink, J., Longo, J., Finn, C.A., and Worthington, E.W., 2011, Geomagnetic referencing in the arctic environment, SPE Arctic and Extreme Environments Conference and Exhibition, Moscow, Russia, 13 p., https://doi.org/10.2118/149629-MS.","productDescription":"13 p.","costCenters":[{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true}],"links":[{"id":257631,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":257623,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.2118/149629-MS","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"Alaska","city":"Deadhorse","noUsgsAuthors":false,"publicationDate":"2011-10-18","publicationStatus":"PW","scienceBaseUri":"505a2760e4b0c8380cd5981c","contributors":{"authors":[{"text":"Podjono, Benny","contributorId":93754,"corporation":false,"usgs":true,"family":"Podjono","given":"Benny","email":"","affiliations":[],"preferred":false,"id":354379,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Beck, Nathan","contributorId":73866,"corporation":false,"usgs":true,"family":"Beck","given":"Nathan","email":"","affiliations":[],"preferred":false,"id":354377,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Buchanan, Andrew","contributorId":90581,"corporation":false,"usgs":true,"family":"Buchanan","given":"Andrew","email":"","affiliations":[],"preferred":false,"id":354378,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Brink, Jason","contributorId":46350,"corporation":false,"usgs":true,"family":"Brink","given":"Jason","email":"","affiliations":[],"preferred":false,"id":354375,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Longo, Joseph","contributorId":20202,"corporation":false,"usgs":true,"family":"Longo","given":"Joseph","email":"","affiliations":[],"preferred":false,"id":354374,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Finn, Carol A. 0000-0003-3144-1645 cafinn@usgs.gov","orcid":"https://orcid.org/0000-0003-3144-1645","contributorId":2144,"corporation":false,"usgs":true,"family":"Finn","given":"Carol","email":"cafinn@usgs.gov","middleInitial":"A.","affiliations":[{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true}],"preferred":false,"id":354373,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Worthington, E.

Monitoring polar bear populations is both arduous and costly and, to be effective, must be a long-term commitment. There are few jurisdictional governments and management boards with a mandate for polar bear research and management, and many have limited resources. Although population monitoring of polar bears has been a focus to some degree within most jurisdictions around the Arctic, of the 19 subpopulations recognised by the IUCN/Species Survival Commission Polar Bear Specialist Group (PBSG), adequate scientific trend data exist for only three of the subpopulations, fair trend data for five and poor or no trend data for the remaining 11 subpopulations (PBSG 2010a). There are especially critical knowledge gaps for the subpopulations in East Greenland, in the Russian Kara and Laptev seas, and in the Chukchi Sea, which is shared between Russia and the United States. The range covered by these subpopulations represents a third of the total area (approx. 23 million km2) of polar bears’ current range, and more than half if the Arctic Basin is included. If we use popular terms, we know close to nothing about polar bears in this portion of their range.</div><div class=\"textLayer\"><div><br data-mce-bogus=\"1\"></div><div>As summer sea-ice extent, and to a lesser degree, spring-time extent, continues to retreat, outpacing model forecasts (Stroeve et al. 2007, Pedersen et al. 2009), polar bears face the challenge of adapting to rapidly changing habitats. There is a need to use current and synthesised information across the Arctic, and to develop new methods that will facilitate monitoring to generate new knowledge at a pan-Arctic scale. The circumpolar dimension can be lost when efforts are channelled into regional monitoring. Developing and implementing a plan that harmonises local, regional and global efforts will increase our power to detect and understand important trends for polar bears, with particular emphasis on how climate warming may differentially affect populations and habitats. Current knowledge is inadequate for a comprehensive understanding of the present and future impact of climate warming and its interaction with other stressors. The cumulative effects are unknown (Laidre et al. 2008). An integrated pan-Arctic research and monitoring plan will improve the ability to detect future trends, identify the most vulnerable subpopulations and guide effective conservation. There is a need to direct attention and resources where data are deficient to understand the mechanisms that drive trends, and to facilitate more effective and timely conservation response.</div></div>","language":"English","publisher":"CAFF Monitoring Series Report No. 1","isbn":"978-9935-431-01-1","usgsCitation":"Vongraven, D., and Peacock, E.L., 2011, Development of a pan-Arctic monitoring plan for polar bears: Background paper, 31 p. .","productDescription":"31 p.

Mapping of river geomorphology and bank characteristics for a 65-mile study area from the Matanuska Glacier to the river mouth provided erodibility information that was assessed along with 1949-2006 erosion to establish erosion hazard data. Braid plain margins were delineated from 1949, 1962, and 2006 orthophotographs to provide detailed measurements of erosion. Bank material and height and geomorphic features within the Matanuska River valley (primarily terraces and tributary fans) were mapped in a Geographic Information System (GIS) from orthophotographs and field observations to provide categories of erodibility and extent of the erodible corridor. The braid plain expanded 861 acres between 1949 and 2006. Erosion in the highest category ranged from 225 to 1,043 feet at reaches of bank an average of 0.5 mile long, affecting 8 percent of the banks but accounting for 64 percent of the erosion. Correlation of erosion to measurable predictor variables was limited to bank height and material. Streamflow statistics, such as peak streamflow or mean annual streamflow, were not clearly linked to erosion, which can occur during the prolonged period of summer high flows where channels are adjacent to an erodible braid plain margin. The historical braid plain, which includes vegetated braid plain bars and islands and active channels, was identified as the greatest riverine hazard area on the basis of its historical occupation. In 2006, the historical braid plain was an average of 15 years old, as determined from the estimated age of vegetation visible in orthophotographs. Bank erosion hazards at the braid plain margins can be mapped by combining bank material, bank height, and geomorphology data. Bedrock bluffs at least 10 feet high (31 percent of the braid plain margins) present no erosion hazard. At unconsolidated banks (63 percent of the braid plain margins), erosion hazards are great and the distinction in hazards between banks of varying height or geomorphology is slight.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/sir20115214","collaboration":"Prepared in cooperation with the Matanuska-Susitna Borough","usgsCitation":"Curran, J.H., and McTeague, M.L., 2011, Geomorphology and bank erosion of the Matanuska River, southcentral Alaska: U.S. Geological Survey Scientific Investigations Report 2011-5214, viii, 50 p.; Appendix; Appendix A; GIS Shapefiles, https://doi.org/10.3133/sir20115214.","productDescription":"viii, 50 p.; Appendix; Appendix A; GIS Shapefiles","numberOfPages":"52","costCenters":[{"id":120,"text":"Alaska Science Center Water","active":true,"usgs":true}],"links":[{"id":116836,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/sir_2011_5214.jpg"},{"id":112037,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/sir/2011/5214/","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"Alaska","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a27a4e4b0c8380cd59a8a","contributors":{"authors":[{"text":"Curran, Janet H. 0000-0002-3899-6275 jcurran@usgs.gov","orcid":"https://orcid.org/0000-0002-3899-6275","contributorId":690,"corporation":false,"usgs":true,"family":"Curran","given":"Janet","email":"jcurran@usgs.gov","middleInitial":"H.","affiliations":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true},{"id":120,"text":"Alaska Science Center Water","active":true,"usgs":true}],"preferred":true,"id":354165,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"McTeague, Monica L.","contributorId":82045,"corporation":false,"usgs":true,"family":"McTeague","given":"Monica","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":354166,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}
