Rocks of the Nixon Fork subterrane are now thought to represent a continental margin sequence rifted from Siberia. The low thermal alteration indices exhibited by the rocks of this area have elicited interest for petroleum exploration.

The glacial and volcanic record of the map area strongly suggests that continental-shelf glaciations and two massive volcanic centers were the dominant controls over landscape development during Pleistocene time. Ancestral Morzhovoi and Emmons Volcanoes were major impediments to flow of shelf glaciers during much of the Pleistocene. Our mapping suggests that the area around Emmons Volcano may have also been an important source area for glaciers during this period. Our data further indicate that Frosty Volcano developed late in the Pleistocene, having had no apparent impact on early Brooks Lake glacial advances but serving as a source area for later glacial advances during late Brooks Lake time. We also believe that major Holocene eruptions of Frosty Volcano have yielded multiple debris and ash flows resulting in the construction of a new south summit cone that filled an earlier crater. Frosty Volcano was the source area for multiple Holocene glacial advances, and its flanks preserve the best record of Neoglacial activity in the map area.</span></p>","largerWorkType":{"id":18,"text":"Report"},"largerWorkTitle":"Geologic studies in Alaska by the U.S. Geological Survey, 1999","largerWorkSubtype":{"id":5,"text":"USGS Numbered Series"},"language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Denver, CO","doi":"10.3133/70180468","usgsCitation":"Wilson, F.H., and Weber, F.R., 2001, Quaternary geology, Cold Bay and False Pass quadrangles, Alaska Peninsula: U.S. Geological Survey Professional Paper, 21 p., https://doi.org/10.3133/70180468.","productDescription":"21 p.","startPage":"51","endPage":"71","numberOfPages":"21","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"links":[{"id":334364,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":334363,"rank":1,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/pp/1633/pp1633_report.pdf#page=59","text":"Start page in larger work"}],"country":"United States","state":"Alaska","otherGeospatial":"Alaska Peninsula, Cold Bay quadrangle, False Pass quadrangle","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -153.72070312499997,\n              59.17592824927136\n            ],\n            [\n              -157.060546875,\n              58.768200159239576\n            ],\n            [\n              -159.609375,\n              56.70450561416937\n            ],\n            [\n              -163.388671875,\n              55.32914440840507\n            ],\n            [\n              -162.158203125,\n              54.67383096593114\n            ],\n            [\n              -157.85156249999997,\n              55.97379820507658\n            ],\n            [\n              -153.6328125,\n              58.722598828043374\n            ],\n            [\n              -153.72070312499997,\n              59.17592824927136\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"58905ef4e4b072a7ac0cad53","contributors":{"authors":[{"text":"Wilson, Frederic H. 0000-0003-1761-6437 fwilson@usgs.gov","orcid":"https://orcid.org/0000-0003-1761-6437","contributorId":67174,"corporation":false,"usgs":true,"family":"Wilson","given":"Frederic","email":"fwilson@usgs.gov","middleInitial":"H.","affiliations":[{"id":119,"text":"Alaska Science Center Geology Minerals","active":true,"usgs":true},{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"preferred":true,"id":661721,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Weber, Florence R.","contributorId":17621,"corporation":false,"usgs":true,"family":"Weber","given":"Florence","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":661722,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Stream width was positively correlated with age at maturity and negatively correlated with predation level. However, salmon spawning on lake beaches were not consistently old, indicating that different factors affect age in riverine- and beach-spawning populations. Body depths of male and female salmon were positively correlated with water depth across all sites, as predicted. However, the mouths of some streams were so shallow that they might select against large or deep-bodied salmon, even in the absence of bear predation.

We compared different analytical approaches for estimating repeatability of egg size of Black Brant. Separate estimates of repeatability for eggs of each clutch size and laying sequence number varied from 0.49 to 0.64. We suggest that using the averaging egg size within clutches results in underestimation of variation within females and thereby overestimates repeatability. We recommend a nested design that partitions egg-size variation within clutches, among clutches within females, and among females. We demonstrate little variation in estimates of repeatability resulting from a nested model controlling for egg laying sequence and a nested model in which we assumed laying sequence was unknown.","language":"English","publisher":"American Ornithological Society","doi":"10.1642/0004-8038(2001)118[0500:EROES]2.0.CO;2","issn":"00048038","usgsCitation":"Flint, P.L., Rockwell, R., and Sedinger, J., 2001, Estimating repeatability of egg size: The Auk, v. 118, no. 2, p. 500-503, https://doi.org/10.1642/0004-8038(2001)118[0500:EROES]2.0.CO;2.","productDescription":"4 p.","startPage":"500","endPage":"503","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"links":[{"id":488118,"rank":2,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1642/0004-8038(2001)118[0500:eroes]2.0.co;2","text":"Publisher Index Page"},{"id":232464,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"118","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a0b3fe4b0c8380cd52637","contributors":{"authors":[{"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":117,"text":"Alaska Science Center Biology WTEB","active":true,"usgs":true},{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"preferred":true,"id":398630,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Rockwell, R.F.","contributorId":22527,"corporation":false,"usgs":true,"family":"Rockwell","given":"R.F.","email":"","affiliations":[],"preferred":false,"id":398629,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Sedinger, J.S.","contributorId":75471,"corporation":false,"usgs":true,"family":"Sedinger","given":"J.S.","email":"","affiliations":[],"preferred":false,"id":398631,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

We captured Semipalmated Sandpiper (<i>Calidris pusilla</i>) chicks at hatch on the Alaskan North Slope and attached 0–3 bands to them. The chicks were resighted and reweighed during the subsequent two weeks. The number of chicks banded varied from 18 to 21 among treatments; 6–9 were resighted, and 6–7 were reweighed, per treatment. The proportion resighted varied from 0.33 to 0.45. The estimated resighting probability, given that we encountered a brood, was 82%. We tested for effects of the bands on survival and mass gain by analyzing whether the proportion of chicks resighted, or their mass, varied with the number of bands. We found no evidence that bands affected the chicks and were able to rule out (with 95% confidence) a decline in survivorship of more than 13% and a loss of mass of more than 10%. Although bands had little if any effect on chicks in our study, we believe their effects should be evaluated whenever survivorship or mass gain are estimated using color-marked chicks.</p>","language":"English","publisher":"Association of Field Ornithologists","doi":"10.1648/0273-8570-72.4.521","usgsCitation":"Bart, J., Battaglia, D.S., and Senner, N.R., 2001, Effects of color bands on Semipalmated Sandpipers banded at hatch: Journal of Field Ornithology, v. 72, no. 4, p. 521-526, https://doi.org/10.1648/0273-8570-72.4.521.","productDescription":"6 p.","startPage":"521","endPage":"526","costCenters":[{"id":290,"text":"Forest and Rangeland Ecosystem Science Center","active":false,"usgs":true}],"links":[{"id":232227,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"72","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a06b7e4b0c8380cd513b1","contributors":{"authors":[{"text":"Bart, Jonathan jon_bart@usgs.gov","contributorId":57025,"corporation":false,"usgs":true,"family":"Bart","given":"Jonathan","email":"jon_bart@usgs.gov","affiliations":[{"id":290,"text":"Forest and Rangeland Ecosystem Science Center","active":false,"usgs":true}],"preferred":false,"id":398440,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Battaglia, Daniel S.","contributorId":78461,"corporation":false,"usgs":true,"family":"Battaglia","given":"Daniel","email":"","middleInitial":"S.","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":false,"id":398441,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Senner, Nathan R.","contributorId":140465,"corporation":false,"usgs":false,"family":"Senner","given":"Nathan","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":398442,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

A wildlife monitoring system was developed in 1996 that used 19 landscape level view sheds, stratified into four sections based on decreasing traffic along the road corridor. Data were collected from 22 samplings of all viewsheds during May-August in 1996 and 1997. In 1997, nine backcountry viewsheds were established in three different areas to determine whether density estimates for each species in the backcountry were higher than those for the same animals in similar road-corridor areas. Densities higher than those in the road corridor were found in one backcountry area for moose and in two backcountry areas for grizzly bears. None of the backcountry areas showed a higher density of caribou. We tested hypotheses that moose, caribou, and grizzly bear distributions were unrelated to the road and traffic. Moose sightings were lower than expected within 300 m of the road. More caribou and grizzly bears than expected occurred between 601 and 900 m from the road, while more moose and fewer caribou than expected occurred between 900 and 1200 m from the road. Bull moose in stratum 1 were distributed farther from the road than bulls and cows in stratum 4; cows in stratum 1 and bul1s in stratum 2 were distributed farther from the road than cows in stratum 4. Grizzly bears in stratum 2 were distributed farther from the road than bears in stratum 3. The distribution of moose sightings suggests traffic avoidance, but the spatial pattern of preferred forage may have had more of an influence. Caribou and grizzly bear distributions indicated no pattern of traffic avoidance.</span></p>","language":"English","publisher":"Arctic Institute of North America","doi":"10.14430/arctic762","usgsCitation":"Yost, A.C., and Wright, R., 2001, Moose, caribou, and grizzly bear distribution in relation to road traffic in Denali National Park, Alaska: Arctic, v. 54, no. 1, p. 41-48, https://doi.org/10.14430/arctic762.","productDescription":"8 p.","startPage":"41","endPage":"48","numberOfPages":"8","costCenters":[{"id":342,"text":"Idaho Cooperative Fish and Wildlife Research Unit","active":false,"usgs":true}],"links":[{"id":489790,"rank":2,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.14430/arctic762","text":"Publisher Index Page"},{"id":232743,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","otherGeospatial":"Denali National Park","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -151.87499958685197,\n              62.80551463545791\n            ],\n            [\n              -148.82488142609475,\n              63.42326621647058\n            ],\n            [\n              -148.8857485290811,\n              63.7272415471883\n            ],\n            [\n              -149.51470859327273,\n              63.71226952329886\n            ],\n            [\n              -149.663494845017,\n              63.57716432493615\n            ],\n            [\n              -150.04222348582053,\n              63.54102756998597\n            ],\n            [\n              -150.39390008085232,\n              63.42931706567359\n            ],\n            [\n              -150.81320679031333,\n              63.46257390741599\n            ],\n            [\n              -150.8673108818568,\n              63.51087858265976\n            ],\n            [\n              -152.23343919332666,\n              63.25940967576716\n            ],\n            [\n              -151.87499958685197,\n              62.80551463545791\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"54","issue":"1","noUsgsAuthors":false,"publicationDate":"2001-01-01","publicationStatus":"PW","scienceBaseUri":"505a5e24e4b0c8380cd7080c","contributors":{"authors":[{"text":"Yost, A.

Species richness was determined by overlaying the distributions of all 60 terrestrial mammalian species found within the state. All landscape variables investigated were correlated with species richness. Areas with high topographic variation and low road density had the highest species richness. Species sensitive to habitat fragmentation were also associated with large forest patches and low road density. These landscape variables may be useful in identifying areas that are important for the conservation of these species. Associations between species distributions and landscape variables were substantiated by published habitat associations. Species with extremely limited distributions were not associated with landscape variables and represent special cases for conservation planners. Rare species, as defined by their limited geographical distribution, were not associated with areas of high species richness (hotspots). The utility of species richness hotspots for conservation planning is disputable.

However, the weather patterns exhibited in Alaska during and just after moderate to strong El Ni&ntilde;o episodes are generally consistent: above normal temperature and precipitation along the Alaskan coast, and above normal temperature and below normal precipitation in the interior, especially through the winter. The warm, dry conditions in the Alaskan interior increase summer wildfire potential. Statistics on the area burned since 1940 show that 15 out of 17 of the biggest fire years occurred during a moderate to strong El Ni&ntilde;o episode. These 15 years account for nearly 63% of the total area burned over the last 58 years. Evidence points to increased dry thunderstorms and associated lightning activity during an El Ni&ntilde;o episode; the percentage of total area burned by lightning caused fires during five episodes increased from a normal of less than 40% to a high of about 96%.</span></p>","language":"English","publisher":"International Association of Wildland Fire","doi":"10.1071/WF01007","issn":"10498001","usgsCitation":"Hess, J.C., Scott, C.A., Hufford, G.L., and Fleming, M.D., 2001, El Niño and its impact on fire weather conditions in Alaska: International Journal of Wildland Fire, v. 10, no. 1, p. 1-13, https://doi.org/10.1071/WF01007.","productDescription":"13 p.","startPage":"1","endPage":"13","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true}],"links":[{"id":232644,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":207580,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1071/WF01007"}],"volume":"10","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a087de4b0c8380cd51b3b","contributors":{"authors":[{"text":"Hess, Jason C.","contributorId":46733,"corporation":false,"usgs":true,"family":"Hess","given":"Jason","email":"","middleInitial":"C.","affiliations":[],"preferred":false,"id":397483,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Scott, Carven A.","contributorId":86146,"corporation":false,"usgs":true,"family":"Scott","given":"Carven","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":397485,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Hufford, Gary L.","contributorId":78502,"corporation":false,"usgs":true,"family":"Hufford","given":"Gary","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":397484,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Fleming, Michael D.","contributorId":102638,"corporation":false,"usgs":true,"family":"Fleming","given":"Michael","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":397486,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Northern Alaska, including the North Slope and adjacent Beaufort and Chukchi continental shelves, holds the lion's share of the total Alaskan endowment of more than 30 billion barrels (4.8 billion m<sup>3</sup>) of oil and natural-gas liquids plus nearly 200 trillion cubic feet (5.7 trillion m<sup>3</sup>) of natural gas. This geologically complex region includes prospective strata within passive-margin, rift, and foreland-basin sequences. Multiple source-rock zones have charged several regionally extensive petroleum systems. Extensional and compressional structures provide ample structural objectives. In addition, recent emphasis on stratigraphic traps has demonstrated significant resource potential in shelf and turbidite systems in Jurassic to Tertiary strata. Despite robust potential, northern Alaska remains a risky exploration frontier - a nexus of geologic complexity, harsh economic conditions, and volatile policy issues. Its role as a major petroleum province in this century will depend on continued technological innovations, not only in exploration and drilling operations, but also in development of huge, currently unmarketable natural-gas resources. Ultimately, policy decisions will determine whether exploration of arctic Alaska will proceed.</p>","language":"English","publisher":"American Association of Petroleum

We describe dive and trip characteristics from time-depth-recorder data collected over a one-month period during summer from four male Pacific walruses in Bristol Bay, Alaska. Dives were classified into four types. Shallow (4 m), short (2.7 min), square-shaped dives accounted for 11% of trip time, and many were probably associated with traveling. Shallow (2 m) and very short (0.5 min) dives composed only 1% of trip time. Deep (41 m), long (7.2 min), square-shaped dives accounted for 46% of trip time and were undoubtedly associated with benthic foraging. V-shaped dives ranged widely in depth, were of moderate duration (4.7 min), and composed 3% of trip time. These dives may have been associated with navigation or exploration of the seafloor for potential prey habitat. Surface intervals between dives were similar among dive types, and generally lasted 1–2 min. Total foraging time was strongly correlated with trip duration and there was no apparent diel pattern of diving in any dive type among animals. We found no correlation between dive duration and postdive surface interval within dive types, suggesting that diving occurred within aerobic dive limits. Trip duration varied considerably within and among walruses (0.3–9.4 d), and there was evidence that some of the very short trips were unrelated to foraging. Overall, walruses were in the water for 76.6% of the time, of which 60.3% was spent diving.</span></p>","language":"English","publisher":"Wiley","doi":"10.1111/j.1748-7692.2001.tb01008.x","issn":"08240469","usgsCitation":"Jay, C., Farley, S.D., and Garner, G., 2001, Summer diving behavior of male walruses in Bristol Bay, Alaska: Marine Mammal Science, v. 17, no. 3, p. 617-631, https://doi.org/10.1111/j.1748-7692.2001.tb01008.x.","productDescription":"15 p.","startPage":"617","endPage":"631","costCenters":[],"links":[{"id":232640,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","otherGeospatial":"Bristol Bay","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -164.98385776938616,\n              54.48712444237478\n            ],\n            [\n              -163.54424902822296,\n              54.776574794300814\n            ],\n            [\n              -162.2982642966867,\n              55.263144226728286\n            ],\n            [\n              -162.26388235802054,\n              55.51065303850737\n            ],\n            [\n              -161.3465159129053,\n              55.83807046903064\n            ],\n            [\n              -160.63021486647438,\n              55.64665722511009\n            ],\n            [\n              -160.06565818325538,\n              55.82382332634407\n            ],\n            [\n              -160.09668696405907,\n              56.30897557213311\n            ],\n            [\n              -158.9723805363865,\n              56.67999773428491\n            ],\n            [\n              -158.49555334871127,\n              56.666325052237\n            ],\n            [\n              -158.38125903190348,\n              56.966763403556314\n            ],\n            [\n              -157.50087363303953,\n              57.41143655985309\n            ],\n            [\n              -157.2252387482563,\n              58.39877996040147\n            ],\n            [\n              -156.59055110921528,\n              59.273562825264406\n            ],\n            [\n              -158.14765618469042,\n              58.849234602583834\n            ],\n            [\n              -158.44363682636643,\n              59.228425251219164\n            ],\n            [\n              -159.15732708757838,\n              58.883539010917616\n            ],\n            [\n              -160.4500670820428,\n              59.14200343281729\n            ],\n            [\n              -161.44405932330287,\n              58.83173901974638\n            ],\n            [\n              -161.550257595399,\n              59.56985090958548\n            ],\n            [\n              -162.45109574296978,\n              60.44339988243891\n            ],\n            [\n              -163.8408673266492,\n              59.943161323577414\n            ],\n            [\n              -165.10002516574653,\n              60.56794890659759\n            ],\n            [\n              -167.4190885038771,\n              60.19423252152259\n            ],\n            [\n              -170.48330867920365,\n              57.22248764033094\n            ],\n            [\n              -169.68288436277425,\n              56.588962599588115\n            ],\n            [\n              -164.98385776938616,\n              54.48712444237478\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"17","issue":"3","noUsgsAuthors":false,"publicationDate":"2006-08-26","publicationStatus":"PW","scienceBaseUri":"505b9f37e4b08c986b31e3fa","contributors":{"authors":[{"text":"Jay, C.V. 0000-0002-9559-2189","orcid":"https://orcid.org/0000-0002-9559-2189","contributorId":67827,"corporation":false,"usgs":true,"family":"Jay","given":"C.V.","affiliations":[],"preferred":false,"id":397341,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Farley, Sean D.","contributorId":27642,"corporation":false,"usgs":false,"family":"Farley","given":"Sean","email":"","middleInitial":"D.","affiliations":[{"id":7058,"text":"Alaska Department of Fish and Game","active":true,"usgs":false}],"preferred":false,"id":397340,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Garner, G.W.","contributorId":80218,"corporation":false,"usgs":true,"family":"Garner","given":"G.W.","email":"","affiliations":[],"preferred":false,"id":397342,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Spruce beetles avoided stands with black spruce (Picea mariana) and selectively killed larger diameter white spruce (Picea glauca), thereby altering forest structure and increasing the dominance of black spruce in the region. Alders (Alnus sp.) and crowberry (Empetrum nigrum) were more abundant in areas with heavy spruce mortality, possibly a response to the death of overstory spruce. Grasses and herbaceous plants did not proliferate as has been recorded following outbreaks in more coastal Alaskan forests. Two species closely tied to coniferous habitats, the tree-nesting Ruby-crowned Kinglet (Regulus calendula) and the red squirrel (Tamiasciurus hudsonicus), a major nest predator, were less abundant in forest stands with high spruce mortality than in low-mortality stands. Understory-nesting birds as a group were more abundant in forest stands with high levels of spruce mortality, although the response of individual bird species to tree mortality was variable. Birds breeding in stands with high spruce mortality likely benefited reproductively from lower squirrel densities and a greater abundance of shrubs to conceal nests from predators.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Canadian Journal of Zoology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1139/cjz-79-9-1678","issn":"00084301","usgsCitation":"Matsuoka, S.M., Handel, C.M., and Ruthrauff, D.R., 2001, Densities of breeding birds and changes in vegetation in an alaskan boreal forest following a massive disturbance by spruce beetles: Canadian Journal of Zoology, v. 79, no. 9, p. 1678-1690, https://doi.org/10.1139/cjz-79-9-1678.","startPage":"1678","endPage":"1690","numberOfPages":"13","costCenters":[],"links":[{"id":208051,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1139/cjz-79-9-1678"},{"id":233436,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"79","issue":"9","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059fe9de4b0c8380cd4ee22","contributors":{"authors":[{"text":"Matsuoka, Steven M. 0000-0001-6415-1885 smatsuoka@usgs.gov","orcid":"https://orcid.org/0000-0001-6415-1885","contributorId":184173,"corporation":false,"usgs":true,"family":"Matsuoka","given":"Steven","email":"smatsuoka@usgs.gov","middleInitial":"M.","affiliations":[{"id":117,"text":"Alaska Science Center Biology WTEB","active":true,"usgs":true}],"preferred":true,"id":395964,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Handel, Colleen M. 0000-0002-0267-7408 cmhandel@usgs.gov","orcid":"https://orcid.org/0000-0002-0267-7408","contributorId":3067,"corporation":false,"usgs":true,"family":"Handel","given":"Colleen","email":"cmhandel@usgs.gov","middleInitial":"M.","affiliations":[{"id":117,"text":"Alaska Science Center Biology WTEB","active":true,"usgs":true}],"preferred":true,"id":395962,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Ruthrauff, Daniel R. 0000-0003-1355-9156 druthrauff@usgs.gov","orcid":"https://orcid.org/0000-0003-1355-9156","contributorId":4181,"corporation":false,"usgs":true,"family":"Ruthrauff","given":"Daniel","email":"druthrauff@usgs.gov","middleInitial":"R.","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":395963,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Disjunct and declining breeding populations coupled with sex-specific differences in seasonal migratory patterns and life history provide a series of hypotheses regarding rates and directionality of gene flow among breeding populations from the Indigirka River Delta, Russia, and the North Slope and Yukon-Kuskokwim Delta, Alaska. The degree of differentiation in mtDNA haplotype frequency among breeding regions and populations within regions was high (ϕ</span><sub>CT</sub><span> = 0.189, </span><i>P</i><span> &lt; 0.01; ϕ</span><sub>SC</sub><span> = 0.059, </span><i>P</i><span> &lt; 0.01, respectively). Eleven of 17 mtDNA haplotypes were restricted to a single breeding region. Genetic differences among regions were considerably lower for nuclear DNA loci (sex-linked: ϕ</span><sub>ST</sub><span> = 0.001, </span><i>P</i><span> &gt; 0.05; biparentally inherited microsatellites: mean θ = 0.001, </span><i>P</i><span> &gt; 0.05) than was observed for mtDNA. Using models explicitly designed for uniparental and biparentally inherited genes, estimates of spatial divergence based on nuclear and mtDNA data together with elements of the species' breeding ecology were used to estimate effective population size and degree of male and female gene flow. Differences in the magnitude and spatial patterns of gene correlations for maternally inherited and nuclear genes revealed that females exhibit greater natal philopatry than do males. Estimates of generational female and male rates of gene flow among breeding regions differed markedly (3.67 × 10</span><sup>−4</sup><span> and 1.28 × 10</span><sup>−2</sup><span>, respectively). Effective population size for mtDNA was estimated to be at least three times lower than that for biparental genes (30,671 and 101,528, respectively). Large disparities in population sizes among breeding areas greatly reduces the proportion of total genetic variance captured by dispersal, which may accelerate rates of inbreeding (i.e., promote higher coancestries) within populations due to nonrandom pairing of males with females from the same breeding population.</span></p>","language":"English","publisher":"Society for the Study of Evolution","doi":"10.1554/0014-3820(2001)055[2105:SBGFIS]2.0.CO;2","issn":"00143820","usgsCitation":"Scribner, K.T., Petersen, M.R., Fields, R.L., Talbot, S.L., Pearce, J.M., and Chesser, R.K., 2001, Sex-biased gene flow in spectacled eiders (Anatidae): Inferences from molecular markers with contrasting modes of inheritance: Evolution, v. 55, no. 10, p. 2105-2115, https://doi.org/10.1554/0014-3820(2001)055[2105:SBGFIS]2.0.CO;2.","productDescription":"11 p.","startPage":"2105","endPage":"2115","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"links":[{"id":233748,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Russia, United States","state":"Alaska","otherGeospatial":"Bering Sea, Indigirka River Delta, North Slope [Alaska], Yukon-Kuskokwim Delta, Alaska","volume":"55","issue":"10","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b8daee4b08c986b3184d3","contributors":{"authors":[{"text":"Scribner, Kim T.","contributorId":146113,"corporation":false,"usgs":false,"family":"Scribner","given":"Kim","email":"","middleInitial":"T.","affiliations":[{"id":135,"text":"Biological Resources Division","active":false,"usgs":true},{"id":16582,"text":"Department of Fisheries and Wildlife and Department of Zoology, 480 Wilson Rd. 13 Natural Resources Building, Michigan State University, East Lansing, MI 48824","active":true,"usgs":false}],"preferred":false,"id":394743,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Petersen, Margaret R. 0000-0001-6082-3189 mrpetersen@usgs.gov","orcid":"https://orcid.org/0000-0001-6082-3189","contributorId":167729,"corporation":false,"usgs":true,"family":"Petersen","given":"Margaret","email":"mrpetersen@usgs.gov","middleInitial":"R.","affiliations":[{"id":117,"text":"Alaska Science Center Biology WTEB","active":true,"usgs":true}],"preferred":true,"id":394742,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Fields, Raymond L.","contributorId":182354,"corporation":false,"usgs":true,"family":"Fields","given":"Raymond","email":"","middleInitial":"L.","affiliations":[{"id":106,"text":"Alaska Biological Science Center","active":false,"usgs":true}],"preferred":false,"id":394739,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Talbot, Sandra L. 0000-0002-3312-7214 stalbot@usgs.gov","orcid":"https://orcid.org/0000-0002-3312-7214","contributorId":140512,"corporation":false,"usgs":true,"family":"Talbot","given":"Sandra","email":"stalbot@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":394741,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"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":394744,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Chesser, Ronald K.","contributorId":113098,"corporation":false,"usgs":true,"family":"Chesser","given":"Ronald","email":"","middleInitial":"K.","affiliations":[],"preferred":false,"id":394740,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

The two-year study at Glen Creek focused on a design of stream and floodplain geometry using hydraulic capacity and shear stress equations. Slope and sinuosity values were based on regional relationships. Design requirements included a channel capacity for a bankfull discharge and a floodplain capacity for a 1.5- to 100-year discharge. Several bio-engineering techniques using alder and willow, including anchored brush bars, streambank hedge layering, seedlings, and cuttings, were tested to dissipate floodwater energy and encourage sediment deposition until natural revegetation stabilized the new floodplains. Permanently monumented cross-sections installed throughout the project site were surveyed every one to three years. Nine years after the project began, a summer flood caused substantial damage to the channel form, including a change in width/depth ratio, slope, and thalweg location. Many of the alder brush bars were heavily damaged or destroyed, resulting in significant bank erosion. This paper reviews the original hydraulic design process, and describes changes to the channel and floodplain geometry over time, based on nine years of cross-section surveys.","largerWorkTitle":"Proceedings of the 2001 Wetlands Engineering and River Restoration Conference","conferenceTitle":"Proceedings of the 2001 Wetlands Engineering and River Restoration Conference","conferenceDate":"27 August 2001 through 31 August 2001","conferenceLocation":"Reno, NV","language":"English","isbn":"0784405816","usgsCitation":"Karle, K., and Densmore, R., 2001, Results From a Channel Restoration Project: Hydraulic Design Considerations, <i>in</i> Proceedings of the 2001 Wetlands Engineering and River Restoration Conference, Reno, NV, 27 August 2001 through 31 August 2001, p. 1127-1138.","startPage":"1127","endPage":"1138","numberOfPages":"12","costCenters":[],"links":[{"id":232528,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505aaaece4b0c8380cd865d6","contributors":{"editors":[{"text":"Hayes D.F.Hayes D.F.","contributorId":128356,"corporation":true,"usgs":false,"organization":"Hayes D.F.Hayes D.F.","id":536501,"contributorType":{"id":2,"text":"Editors"},"rank":1}],"authors":[{"text":"Karle, K.F.","contributorId":18141,"corporation":false,"usgs":true,"family":"Karle","given":"K.F.","email":"","affiliations":[],"preferred":false,"id":397723,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Densmore, R.V.","contributorId":72953,"corporation":false,"usgs":true,"family":"Densmore","given":"R.V.","email":"","affiliations":[],"preferred":false,"id":397724,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Our earlier research suggests that ovigerous crabs aggregate at the same brooding locations for many years. Within these locations, ovigerous females occur in high densities, with the majority of the aggregation buried within the sediment. These locations often have similar water depths and sediment types and appear to be critical for this life history stage. Our study was designed to examine the bathymetric distribution of Dungeness crabs in bays with and without sea otters at eight locations within the Glacier Bay area by conducting transects with a video-equipped manned submersible. Two of the bays investigated contained large aggregations of ovigerous females. At both sites the substrate was composed primarily of sand. However, only a small percentage of the 33 km of transects were classified as sand. These data suggest that sand substrate may be a limiting resource. Since crab brooding aggregations represent a large portion of the crab population within a small area, and because they are a critical component of Dungeness life history, areas with these characteristics need to be investigated, mapped, and protected from development or exploitation. The areas requiring protection from the impact of anthropogenic wastes, fishing, and logging activities could be quite small, thus limiting conflict with alternative users.</p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Spatial processes and management of marine populations","largerWorkSubtype":{"id":12,"text":"Conference

This CD-ROM contains 97 digitized color 35-mm images which represent a small fraction of thousands of photographs taken by Alaska Volcano Observatory scientists, other researchers, and private citizens. The photographs were selected to portray Alaska's volcanoes, to document recent eruptive activity, and to illustrate the range of volcanic phenomena observed in Alaska. \r\nThese images are for use by the interested public, multimedia producers, desktop publishers, and the high-end printing industry. The digital images are stored in the 'images' folder and can be read across Macintosh, Windows, DOS, OS/2, SGI, and UNIX platforms with applications that can read JPG (JPEG - Joint Photographic Experts Group format) or PCD (Kodak's PhotoCD (YCC) format) files. Throughout this publication, the image numbers match among the file names, figure captions, thumbnail labels, and other references. Also included on this CD-ROM are Windows and Macintosh viewers and engines for keyword searches (Adobe Acrobat Reader with Search).

The Yukon River is also fundamental to the ecosystems of the eastern Bering Sea and Chukchi Sea, providing most of the freshwater runoff, sediments, and dissolved solutes. Despite its remoteness and perceived invulnerability, the Yukon River Basin is changing. For example, records of air temperature during 1961-1990 indicate a warming trend of about 0.75 deg C per decade at latitudes where the Yukon River is located. Increases in temperature will have wide-ranging effects on permafrost distribution, glacial runoff and the movement of carbon and nutrients within and from the basin. In addition, Alaska has many natural resources such as timber, minerals, gas, and oil that may be developed in future years. As a consequence of these changes, several issues of scientific and cultural concern have come to the forefront. At present, water quality data for the Yukon River Basin are very limited.

The department selected these sites from approximately 806 State-owned bridges as potentially susceptible to scour during extreme floods. Pier scour and contraction scour were computed for the selected bridges by using methods recommended by the Federal Highway Administration. The U.S. Geological Survey used a four-step procedure to estimate scour: (1) Compute magnitudes of the 100- and 500-year floods. (2) Determine cross-section geometry and hydraulic properties for each bridge site. (3) Compute the water-surface profile for the 100- and 500-year floods. (4) Compute contraction and pier scour. This procedure is unique because the cross sections were developed from existing data on file to make a quantitative estimate of scour. This screening method has the advantage of providing scour depths and bed elevations for comparison with bridge-foundation elevations without the time and expense of a field survey. Four examples of bridge-scour analyses are summarized in the appendix.","language":"ENGLISH","doi":"10.3133/wri004151","usgsCitation":"Heinrichs, T.A., Kennedy, B., Langley, D.E., and Burrows, R.L., 2001, Methodology and Estimates of Scour at Selected Bridge Sites in Alaska: U.S. Geological Survey Water-Resources Investigations Report 2000-4151, iii, 44 p. : ill., map ; 28 cm. , https://doi.org/10.3133/wri004151.","productDescription":"iii, 44 p. : ill., map ; 28 cm.

All ground-water samples were from aquifers composed of glacial or alluvial sediments. The water samples were used to determine the occurrence and distribution of selected major ions, nutrients, trace elements, volatile organic compounds, pesticides, radioisotopes, and environmental isotopes. Of 34 samples, 29 were from wells chosen by using a grid-based random-selection process. Water samples from five major public-supply wells also were collected.\r\n\r\n \r\n\r\nRadon-222 and arsenic concentrations exceeded drinking-water standards proposed by the U.S. Environmental Protection Agency in 39 and 18 percent of sampled wells, respectively. The highest radon concentration measured during this study was 610 picocuries per liter; 12 of 31 samples exceeded the proposed maximum contaminant level of 300 picocuries per liter. The highest arsenic concentration was 29 micrograms per liter; 6 of 34 samples exceeded the proposed maximum contaminant level of 10 micrograms per liter. Human activities may be increasing the concen- tration of nitrate in ground water, but nitrate concentrations in all samples were less than the maximum contaminant level of 10 milligrams per liter as nitrogen. Concentrations of nitrate were highest in Anchorage and were as great as 4.8 milligrams per liter as nitrogen. Dissolved-solids concentrations ranged from 77 to 986 milligrams per liter; only 2 of 34 wells yielded water having greater than 500 milligrams per liter. Iron and manganese concentrations exceeded secondary maximum contaminant levels in 18 and 42 percent of samples, respectively. \r\n\r\n \r\n\r\nConcentrations of all pesticides and volatile organic compounds detected in ground-water samples were very low, less than 1 microgram per liter. No pesticide or volatile organic compounds were detected at concentrations exceeding drinking-water standards or guidelines. Water samples from one-half of the wells sampled had no detectable concentrations of pesticides or volatile organic carbons, at the parts-per-billion level.\r\n\r\n \r\n\r\nConcentrations of stable isotopes of hydrogen and oxygen in ground-water samples were similar to concentrations expected for modern precipitation and for water that has been affected by evaporation. Tritium activities and concentrations of chlorofluorocarbons indicated that the water samples collected from most wells were recharged less than 50 years ago.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wri014208","usgsCitation":"Glass, R.L., 2001, Ground-water quality, Cook Inlet Basin, Alaska, 1999 (Version 1.0): U.S. Geological Survey Water-Resources Investigations Report 2001-4208, vii, 58 p., https://doi.org/10.3133/wri014208.","productDescription":"vii, 58 p.","costCenters":[],"links":[{"id":161722,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":411667,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_46459.htm","linkFileType":{"id":5,"text":"html"}},{"id":3859,"rank":2,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.water.usgs.gov/wri01-4208","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"Alaska","otherGeospatial":"Cook Inlet Basin","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -151.4667,\n              61.75\n            ],\n            [\n              -151.4667,\n              61.25\n            ],\n            [\n              -149,\n              61.25\n            ],\n            [\n              -149,\n              61.75\n            ],\n            [\n              -151.4667,\n              61.75\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","edition":"Version 1.0","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a9ee4b07f02db660b2c","contributors":{"authors":[{"text":"Glass, Roy L.","contributorId":86813,"corporation":false,"usgs":true,"family":"Glass","given":"Roy","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":230838,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

In this study, multitemporal phenological characteristics of Alaskan vegetation were studied for the State as a whole, and 19 of 20 ecoregions were studied using seasonally truncated, composited advanced very high resolution radiometer derived normalized difference vegetation index (NDVI) data. Phenological characteristics included four temporal and six greenness metrics derived for each year from 1991 to 1997. Temporal metrics included date of onset of greenness, last day of greenness, date of maximum greenness, and total days of greenness. Greenness metrics consisted of NDVI values recorded during the onset and last day of greenness, maximum greenness, mean greenness for the growing season, and estimated rates of greenup and greendown in the spring and autumn, respectively. Results indicated that over many areas of Alaska there was a trend toward earlier onset of greenness each spring from 1992 to 1997, but the last day of greenness in the autumn was roughly the same. Earlier greenup dates in the spring resulted in a lengthened growing season greenup of up to 20 days in some areas of Alaska from 1992 to 1997. Climate data, however, did not always corroborate these findings. In general, greenness values dropped from 1991 to 1992 and then increased from 1992 to 1997. Values obtained after 1991 may have been affected by atmospheric perturbations owing to the 1991 Mt. Pinatubo eruption and lasting until at least 1997.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Anchorage, AK","doi":"10.3133/ofr0111","usgsCitation":"Markon, C., 2001, Seven-year phenological record of the Alaskan ecoregions derived from advanced very high resolution radiometer normalized difference vegetation index data: U.S. Geological Survey Open-File Report 2001-11, 57 p., https://doi.org/10.3133/ofr0111.","productDescription":"57 p.","numberOfPages":"58","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true},{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true}],"links":[{"id":175305,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":4180,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2001/0011/2001-OFR2001-11.pdf","text":"Report","size":"263 KB","linkFileType":{"id":1,"text":"pdf"},"description":"OFR 2001-11"}],"country":"United States","state":"Alaska","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49dce4b07f02db5e1518","contributors":{"authors":[{"text":"Markon, Carl J.","contributorId":80305,"corporation":false,"usgs":true,"family":"Markon","given":"Carl J.","affiliations":[],"preferred":false,"id":241314,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Data collected included macroinvertebrate abundance, water chemistry, and trace elements in bed sediments. Macroinvertebrate relative-abundance data were edited and used in metric and index calculations. Population density was used as a surrogate for urbanization. Cluster analysis (unweighted-paired-grouping method) using arithmetic means of macroinvertebrate presence-absence data showed a well-defined separation between urbanized and nonurbanized sites as well as extracted sites that did not cleanly fall into either category. Water quality in Anchorage generally declined with increasing urbanization (population density). Of 59 variables examined, 31 correlated with urbanization. Local regression analysis extracted 11 variables that showed a significant impairment threshold response and 6 that showed a significant linear response. Significant biological variables for determining the impairment threshold in this study were the Margalef diversity index, Ephemeroptera-Plecoptera-Trichoptera taxa richness, and total taxa richness. Significant thresholds were observed in the water-chemistry variables conductivity, dissolved organic carbon, potassium, and total dissolved solids. Significant thresholds in trace elements in bed sediments included arsenic, iron, manganese, and lead. Results suggest that sites in Anchorage that have ratios of population density to road density greater than 70, storm-drain densities greater than 0.45 miles per square mile, road densities greater than 4 miles per square mile, or population densities greater than 125-150 persons per square mile may require further monitoring to determine if the stream has become impaired. This population density is far less than the 1,000 persons per square mile used by the U.S. Census Bureau to define an urban area.","language":"ENGLISH","doi":"10.3133/wri014278","usgsCitation":"Ourso, R.T., 2001, Effects of urbanization on benthic macroinvertebrate communities in streams, Anchorage, Alaska (Version 1.0): U.S. Geological Survey Water-Resources Investigations Report 2001-4278, 38 p., https://doi.org/10.3133/wri014278.","productDescription":"38 p.","costCenters":[],"links":[{"id":161627,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":3868,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.water.usgs.gov/wri014278","linkFileType":{"id":5,"text":"html"}}],"edition":"Version 1.0","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a27e4b07f02db60ff53","contributors":{"authors":[{"text":"Ourso, Robert T. 0000-0002-5952-8681 rtourso@usgs.gov","orcid":"https://orcid.org/0000-0002-5952-8681","contributorId":203207,"corporation":false,"usgs":true,"family":"Ourso","given":"Robert","email":"rtourso@usgs.gov","middleInitial":"T.","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":230884,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}
