Porosity was determined from the LWD bulk density log and core-derived values of grain density. In situ measurements of pore-fluid salinity as well as formation temperature define a background trend for pore-fluid resistivity at each drill site. The LWD data were used to define sets of empirical Archie-constants for different depth-intervals of the logged borehole at all sites drilled during the second Ulleung Basin Gas Hydrate Drilling Expedition (UBGH2). A clustering of data with distinctly different trend-lines is evident in the cross-plot of porosity and formation factor for all sites drilled during UBGH2. The reason for the clustering is related to the difference between hemipelagic sediments (mostly covering the top ∼100 mbsf) and mass-transport deposits (MTD) and/or the occurrence of biogenic opal. For sites located in the north-eastern portion of the Ulleung Basin a set of individual Archie-parameters for a shallow depth interval (hemipelagic) and a deeper MTD zone was achieved. The deeper zone shows typically higher resistivities for the same range of porosities seen in the upper zone, reflecting a shift in sediment properties. The presence of large amounts of biogenic opal (up to and often over 50% as defined by XRD data) was especially observed at Sites UBGH2-2_1 and UBGH2-2_2 (as well as UBGH1-9 from a previous drilling expedition in 2007). The boundary between these two zones can also easily be identified in gamma-ray logs, which also show unusually low readings in the opal-rich interval. Only by incorporating different Archie-parameters for the different zones a reasonable estimate of gas hydrate saturation was achieved that also matches results from other techniques such as pore-fluid freshening, velocity-based calculations, and pressure-core degassing experiments. Seismically, individual boundaries between zones were determined using a grid of regional 2D seismic data. Zoning from the Archie-analysis for sites in the south-western portion of the Ulleung Basin was also observed, but at these sites it is linked to individually stacked MTDs only and does not reflect a mineralogical occurrence of biogenic opal or hemipelagic sedimentation. The individual MTD events represent differently compacted material often associated with a strong decrease in porosity (and increase in density), warranting a separate set of empirical Archie-parameters.","language":"English","publisher":"Elsevier","doi":"10.1016/j.marpetgeo.2013.03.014","usgsCitation":"Riedel, M., Collett, T.S., Kim, H., Bahk, J., Kim, J., Ryu, B., and Kim, G., 2013, Large-scale depositional characteristics of the Ulleung Basin and its impact on electrical resistivity and Archie-parameters for gas hydrate saturation estimates: Marine and Petroleum Geology, v. 47, p. 222-235, https://doi.org/10.1016/j.marpetgeo.2013.03.014.","productDescription":"14 p.","startPage":"222","endPage":"235","numberOfPages":"14","ipdsId":"IP-040872","costCenters":[{"id":164,"text":"Central Energy Resources Science Center","active":true,"usgs":true}],"links":[{"id":282028,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":281996,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.marpetgeo.2013.03.014"}],"country":"Korea","otherGeospatial":"East Sea Of Korea;Ulleung Basin","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ 129.0,35.0 ], [ 129.0,38.0 ], [ 133.0,38.0 ], [ 133.0,35.0 ], [ 129.0,35.0 ] ] ] } } ] }","volume":"47","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53cd641ce4b0b290850ff3e6","contributors":{"authors":[{"text":"Riedel, Michael","contributorId":7518,"corporation":false,"usgs":true,"family":"Riedel","given":"Michael","email":"","affiliations":[],"preferred":false,"id":489967,"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":255,"text":"Energy Resources Program","active":true,"usgs":true},{"id":164,"text":"Central Energy Resources Science Center","active":true,"usgs":true},{"id":171,"text":"Central Mineral and Environmental Resources Science Center","active":true,"usgs":true},{"id":678,"text":"Woods Hole Coastal and Marine Science Center","active":true,"usgs":true}],"preferred":true,"id":489966,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Kim, H.-S.","contributorId":46874,"corporation":false,"usgs":true,"family":"Kim","given":"H.-S.","email":"","affiliations":[],"preferred":false,"id":489969,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Bahk, J.-J.","contributorId":99891,"corporation":false,"usgs":true,"family":"Bahk","given":"J.-J.","affiliations":[],"preferred":false,"id":489972,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Kim, J.-H.","contributorId":26395,"corporation":false,"usgs":true,"family":"Kim","given":"J.-H.","email":"","affiliations":[],"preferred":false,"id":489968,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Ryu, B.-J.","contributorId":59348,"corporation":false,"usgs":true,"family":"Ryu","given":"B.-J.","email":"","affiliations":[],"preferred":false,"id":489970,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Kim, G.-Y.","contributorId":77454,"corporation":false,"usgs":true,"family":"Kim","given":"G.-Y.","email":"","affiliations":[],"preferred":false,"id":489971,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}

Specifically, this report provides an optimal harvest quota for the 2013-2015 hunting seasons and describes a process for evaluating whether emergency hunting closures would be needed during that period. By combining varying hypotheses about survival and reproduction, a suite of nine models have been developed that represent a wide range of possibilities concerning the extent to which demographic rates are density dependent or independent, and the extent to which spring temperatures are important. The most current set of monitoring information was used to update model weights for the 1991 – 2012 period. Current model weights suggest no evidence for density-dependent survival. These results suggest that the pink-footed goose population may have recently experienced a release from density-dependent mechanisms, corresponding to the period of most rapid growth in population size. There was equivocal evidence for the effect of May temperature days (number of days with temperatures above freezing) on survival and on reproduction. The optimal harvest strategy suggests that the appropriate annual harvest quota for the 20132015 period is 15,000; hence there is no need to take emergency measures to close the upcoming hunting season. For comparison, the estimated harvest in 2012 was 11,000. If the harvest quota of 15,000 were met, the autumn 2013 population count is expected to be 76,000. If only the most recent 3-year mean harvest were realized (11,500), an autumn population size of 80,000 thousand is expected. Thus, it may be that harvest is approaching the magnitude needed to stabilize the population.","language":"English","publisher":"Aarhus University, DCE – Danish Centre for Environment and Energy","issn":"2245-019X","isbn":"978-87-7156-038-1","usgsCitation":"Johnson, F.A., and Madsen, J., 2013, Adaptive harvest management for the Svalbard population of pink-footed geese: assessment for the 2013-2015 hunting seasons: Technical Report from DCE - Danish Centre for Environment and Energy 28, 19 p.","productDescription":"19 p.","numberOfPages":"22","ipdsId":"IP-049210","costCenters":[{"id":566,"text":"Southeast Ecological Science Center","active":true,"usgs":true}],"links":[{"id":279185,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":279186,"type":{"id":15,"text":"Index Page"},"url":"https://dce.au.dk/en/publications/tr/nr-1-49/"}],"country":"Denmark;Norway","otherGeospatial":"Svalbard","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"528c96aae4b0c629af44dd92","contributors":{"authors":[{"text":"Johnson, Fred A. 0000-0002-5854-3695 fjohnson@usgs.gov","orcid":"https://orcid.org/0000-0002-5854-3695","contributorId":2773,"corporation":false,"usgs":true,"family":"Johnson","given":"Fred","email":"fjohnson@usgs.gov","middleInitial":"A.","affiliations":[{"id":566,"text":"Southeast Ecological Science Center","active":true,"usgs":true},{"id":455,"text":"National Wetlands Research Center","active":true,"usgs":true},{"id":17705,"text":"Wetland and Aquatic Research Center","active":true,"usgs":true}],"preferred":true,"id":483313,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Madsen, Jesper","contributorId":9950,"corporation":false,"usgs":true,"family":"Madsen","given":"Jesper","affiliations":[],"preferred":false,"id":483314,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

From a circular, polar low-altitude mapping orbit, GRaND sampled the regolith to decimeter depths with a spatial resolution of about 300 km. At this spatial scale, the variation in neutron absorption is about seven times lower than that of the Moon. The observed variation is consistent with the range of absorption for howardite whole-rock compositions, which further supports the connection between Vesta and the howardite, eucrite, and diogenite meteorites. We find a strong correlation between neutron absorption and the percentage of eucritic materials in howardites and polymict breccias, which enables petrologic mapping of Vesta's surface. The distribution of basaltic eucrite and diogenite determined from neutron absorption measurements is qualitatively similar to that indicated by visible and near infrared spectroscopy. The Rheasilvia basin and ejecta blanket has relatively low absorption, consistent with Mg-rich orthopyroxene. Based on a combination of Fe and neutron absorption measurements, olivine-rich lithologies are not detected on the spatial scales sampled by GRaND. The sensitivity of GRaND to the presence of mantle material is described and implications for the absence of an olivine signature are discussed. High absorption values found in Vesta's “dark” hemisphere, where exogenic hydrogen has accumulated, indicate that this region is richer in basaltic eucrite, representative of Vesta's ancient upper crust.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Meteoritics and Planetary Science","largerWorkSubtype":{"id":10,"text":"Journal

Seven ages ranging from Miocene to late Holocene have been proposed for them. This paper presents new information—chiefly subsurface stratigraphic data, OSL dates, and geomorphic evidence—that indicates that the Great Sand Dunes began to form in the latter part of the middle Pleistocene. The dunes overlie a thick wedge of piedmont-slope deposits, which in turn overlies sediment of Lake Alamosa, a paleolake that began to drain about 440 ka. The wedge of piedmont-slope deposits extends westward for at least 23 km and is as much as 60 m thick at a distance of 10 km from the Sangre de Cristo Range. Ostracodes from one well indicate that the eastern shoreline of Lake Alamosa extended to within 4.3 km of where the Great Sand Dunes eventually formed. The time represented by the wedge of piedmont-slope deposits is not known exactly, but the wedge post-dates 440 ka and was in place prior to 130 ka because by then the dunes overlying it were sufficiently close and tall enough to obstruct streams draining from the Sangre de Cristo Range.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Quaternary Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"American Quaternary Association","publisherLocation":"New York, NY","doi":"10.1016/j.yqres.2013.09.009","usgsCitation":"Madole, R.F., Mahan, S., Romig, J.H., and Havens, J., 2013, Constraints on the age of the Great Sand Dunes, Colorado, from subsurface stratigraphy and OSL dates: Quaternary Research, v. 80, no. 3, p. 435-446, https://doi.org/10.1016/j.yqres.2013.09.009.","productDescription":"12 p.","startPage":"435","endPage":"446","numberOfPages":"12","costCenters":[],"links":[{"id":291322,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":291321,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.yqres.2013.09.009"}],"volume":"80","issue":"3","noUsgsAuthors":false,"publicationDate":"2017-01-20","publicationStatus":"PW","scienceBaseUri":"57f7f21de4b0bc0bec0a01bc","contributors":{"authors":[{"text":"Madole, Richard F. 0000-0002-9081-570X madole@usgs.gov","orcid":"https://orcid.org/0000-0002-9081-570X","contributorId":1340,"corporation":false,"usgs":true,"family":"Madole","given":"Richard","email":"madole@usgs.gov","middleInitial":"F.","affiliations":[{"id":318,"text":"Geosciences and Environmental Change Science Center","active":true,"usgs":true}],"preferred":true,"id":497086,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Mahan, Shannon 0000-0001-5214-7774 smahan@usgs.gov","orcid":"https://orcid.org/0000-0001-5214-7774","contributorId":1215,"corporation":false,"usgs":true,"family":"Mahan","given":"Shannon","email":"smahan@usgs.gov","affiliations":[{"id":211,"text":"Crustal Geophysics and Geochemistry Science Center","active":true,"usgs":true}],"preferred":false,"id":497085,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Romig, Joseph H.","contributorId":24704,"corporation":false,"usgs":true,"family":"Romig","given":"Joseph","email":"","middleInitial":"H.","affiliations":[],"preferred":false,"id":497087,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Havens, Jeremy C.","contributorId":40912,"corporation":false,"usgs":true,"family":"Havens","given":"Jeremy C.","affiliations":[],"preferred":false,"id":497088,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Disturbance in a watershed combined with alterations to the hydro-climatologic regime may result in changes to the sediment flux, and exacerbate the impacts of extreme events (such as large-magnitude floods) on sediment transport. In the San Francisco Estuary, suspended sediment has been declining over the past 30 years as a result of declining sediment supply, contributing to dramatic changes in the ecology and geomorphology of the estuary. However, the decline has not been gradual. Recent observations of an abrupt decrease in suspended sediments in the San Francisco Bay have been explained by a model that suggests that the step change has occurred due to exceedance of a sediment regulation threshold that triggered the change from a sediment transport regime to a supply-limited system. We investigated structural changes in the historical record of total suspended solids (TSS) concentration measured in the upper estuary to verify the model predictions. TSS in the upper estuary exhibited an abrupt step decrease in 1983 corresponding to the record-high winter and summer flows from the 1982 to 1983 El Niño event. After this step change, TSS concentrations had a significant declining trend despite subsequent near-record high flows. The abrupt change in TSS followed by the declining trend provides evidence for the hypothesis of sediment supply limitation in the San Francisco Estuary.","language":"English","publisher":"Elsevier","doi":"10.1016/j.margeo.2013.05.008","usgsCitation":"Hestir, E.L., Schoellhamer, D., Morgan-King, T., and Ustin, S.L., 2013, A step decrease in sediment concentration in a highly modified tidal river delta following the 1983 El Niño floods: Marine Geology, v. 345, p. 304-313, https://doi.org/10.1016/j.margeo.2013.05.008.","productDescription":"10 p.","startPage":"304","endPage":"313","numberOfPages":"10","ipdsId":"IP-022095","costCenters":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true},{"id":552,"text":"San Francisco Bay-Delta","active":false,"usgs":true}],"links":[{"id":282572,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"California","city":"San Francisco","otherGeospatial":"San Francisco Estuary","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -122.7997,37.3985 ], [ -122.7997,38.5997 ], [ -120.5035,38.5997 ], [ -120.5035,37.3985 ], [ -122.7997,37.3985 ] ] ] } } ] }","volume":"345","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53cd4a9fe4b0b290850efe34","contributors":{"editors":[{"text":"Barnard, Patrick L. 0000-0003-1414-6476 pbarnard@usgs.gov","orcid":"https://orcid.org/0000-0003-1414-6476","contributorId":147147,"corporation":false,"usgs":true,"family":"Barnard","given":"Patrick L.","email":"pbarnard@usgs.gov","affiliations":[{"id":520,"text":"Pacific Coastal and Marine Science Center","active":true,"usgs":true}],"preferred":true,"id":790431,"contributorType":{"id":2,"text":"Editors"},"rank":1},{"text":"Jaffe, Bruce E. 0000-0002-8816-5920 bjaffe@usgs.gov","orcid":"https://orcid.org/0000-0002-8816-5920","contributorId":2049,"corporation":false,"usgs":true,"family":"Jaffe","given":"Bruce","email":"bjaffe@usgs.gov","middleInitial":"E.","affiliations":[{"id":520,"text":"Pacific Coastal and Marine Science Center","active":true,"usgs":true},{"id":186,"text":"Coastal and Marine Geology Program","active":true,"usgs":true}],"preferred":true,"id":790432,"contributorType":{"id":2,"text":"Editors"},"rank":2},{"text":"Schoellhamer, David H. 0000-0001-9488-7340 dschoell@usgs.gov","orcid":"https://orcid.org/0000-0001-9488-7340","contributorId":631,"corporation":false,"usgs":true,"family":"Schoellhamer","given":"David H.","email":"dschoell@usgs.gov","affiliations":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"preferred":true,"id":790433,"contributorType":{"id":2,"text":"Editors"},"rank":3}],"authors":[{"text":"Hestir, Erin L.","contributorId":101181,"corporation":false,"usgs":true,"family":"Hestir","given":"Erin","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":490623,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Schoellhamer, David H. 0000-0001-9488-7340 dschoell@usgs.gov","orcid":"https://orcid.org/0000-0001-9488-7340","contributorId":631,"corporation":false,"usgs":true,"family":"Schoellhamer","given":"David H.","email":"dschoell@usgs.gov","affiliations":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"preferred":true,"id":490620,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Morgan-King, Tara 0000-0001-5632-5232","orcid":"https://orcid.org/0000-0001-5632-5232","contributorId":32804,"corporation":false,"usgs":true,"family":"Morgan-King","given":"Tara","affiliations":[],"preferred":false,"id":490621,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Ustin, Susan L.","contributorId":52878,"corporation":false,"usgs":false,"family":"Ustin","given":"Susan","email":"","middleInitial":"L.","affiliations":[{"id":7214,"text":"University of California, Davis","active":true,"usgs":false}],"preferred":false,"id":490622,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Subsequently stored in a nearby museum, the remains became lost for almost 36 years. In a recent effort to repatriate the remains, it was necessary to fit them into a cultural chronology in order to determine the appropriate tribe(s) for consultation pursuant to the Native American Grave Protection and Repatriation Act (NAGPRA). Because the remains were found in an eroded context with no artifacts or funerary objects, their age was unknown. Having been asked to avoid destructive dating methods such as radiocarbon dating, the authors used Optically Stimulated Luminescence (OSL) to date the sediments embedded in the cranium. The OSL analyses yielded reliable dates between A.D. 1415 and A.D. 1495. Accordingly, we conclude that the remains were interred somewhat earlier than A.D. 1415, but no later than A.D. 1495. We believe the remains are from individuals ancestral to the Ute Mouache Band, which is now being contacted for repatriation efforts. Not only do our methods contribute to the immediate repatriation efforts, they provide archaeologists with a versatile, non-destructive, numerical dating method that can be used in many burial contexts.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Advances in Archaeological Practice: A Journal of the Society for American Archaeology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Society for American Archaeology","publisherLocation":"Washington, D.C.","doi":"10.7183/2326-3768.1.2.91","usgsCitation":"Lail, W.K., Sammeth, D., Mahan, S., and Nevins, J., 2013, A non-destructive method for dating human remains: Advances in Archaeological Practice: A Journal of the Society for American Archaeology, v. 1, no. 2, p. 91-103, https://doi.org/10.7183/2326-3768.1.2.91.","productDescription":"13 p.","startPage":"91","endPage":"103","numberOfPages":"13","ipdsId":"IP-051172","costCenters":[{"id":211,"text":"Crustal Geophysics and Geochemistry Science Center","active":true,"usgs":true}],"links":[{"id":291168,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":291167,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.7183/2326-3768.1.2.91"}],"country":"United States","state":"New Mexico","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -105.3777,36.2176 ], [ -105.3777,36.9962 ], [ -104.0072,36.9962 ], [ -104.0072,36.2176 ], [ -105.3777,36.2176 ] ] ] } } ] }","volume":"1","issue":"2","noUsgsAuthors":false,"publicationDate":"2017-01-16","publicationStatus":"PW","scienceBaseUri":"5810cbcee4b0f497e7974c39","contributors":{"authors":[{"text":"Lail, Warren K.","contributorId":77060,"corporation":false,"usgs":true,"family":"Lail","given":"Warren","email":"","middleInitial":"K.","affiliations":[],"preferred":false,"id":496695,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Sammeth, David","contributorId":54123,"corporation":false,"usgs":true,"family":"Sammeth","given":"David","email":"","affiliations":[],"preferred":false,"id":496694,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Mahan, Shannon 0000-0001-5214-7774","orcid":"https://orcid.org/0000-0001-5214-7774","contributorId":19239,"corporation":false,"usgs":true,"family":"Mahan","given":"Shannon","affiliations":[],"preferred":false,"id":496692,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Nevins, Jason","contributorId":40136,"corporation":false,"usgs":true,"family":"Nevins","given":"Jason","email":"","affiliations":[],"preferred":false,"id":496693,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Current studies reinforce earlier findings of major climate-change-related impacts on biological systems and document new, more subtle after-effects. For example, many species are shifting their distributions and phenologies at faster rates than were recorded just a few years ago; however, responses are not uniform across species. Shifts have been idiosyncratic and in some cases counterintuitive, promoting new community compositions and altering biotic interactions. Although genetic diversity enhances species' potential to respond to variable conditions, climate change may outpace intrinsic adaptive capacities and increase the relative vulnerabilities of many organisms.

By this means, we see that surficial sand-sized sediment in the San Francisco Bay Coastal System comes primarily from the Sierra Nevada and associated terranes by way of the Sacramento and San Joaquin Rivers and is transported with little dilution through the San Francisco Bay and out the Golden Gate. Heavy minerals document a slight change from the strictly Sierran-Sacramento mineralogy at the confluence of the two rivers to a composition that includes minor amounts of chert and other Franciscan Complex components west of Carquinez Strait. Between Carquinez Strait and the San Francisco Bar, Sierran sediment is intermingled with Franciscan-modified Sierran sediment. The latter continues out the Gate and turns southward towards beaches of the San Francisco Peninsula. The Sierran sediment also fans out from the San Francisco Bar to merge with a Sierran province on the shelf in the Gulf of the Farallones. Beach-sand sized sediment from the Russian River is transported southward to Point Reyes where it spreads out to define a Franciscan sediment province on the shelf, but does not continue southward to contribute to the sediment in the Golden Gate area.","language":"English","publisher":"Elsevier","doi":"10.1016/j.margeo.2013.05.012","usgsCitation":"Wong, F.L., Woodrow, D., and McGann, M., 2013, Heavy mineral analysis for assessing the provenance of sandy sediment in the San Francisco Bay Coastal System: Marine Geology, v. 345, p. 170-180, https://doi.org/10.1016/j.margeo.2013.05.012.","productDescription":"11 p.","startPage":"170","endPage":"180","numberOfPages":"11","ipdsId":"IP-039170","costCenters":[{"id":186,"text":"Coastal and Marine Geology Program","active":true,"usgs":true},{"id":520,"text":"Pacific Coastal and Marine Science Center","active":true,"usgs":true},{"id":552,"text":"San Francisco Bay-Delta","active":false,"usgs":true}],"links":[{"id":278981,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"California","otherGeospatial":"San Francisco Bay Coastal System","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -123.0,37.5 ], [ -123.0,38.5 ], [ -121.5,38.5 ], [ -121.5,37.5 ], [ -123.0,37.5 ] ] ] } } ] }","volume":"345","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"527e586ce4b02d2057dd95e5","contributors":{"editors":[{"text":"Barnard, Patrick L. 0000-0003-1414-6476 pbarnard@usgs.gov","orcid":"https://orcid.org/0000-0003-1414-6476","contributorId":147147,"corporation":false,"usgs":true,"family":"Barnard","given":"Patrick L.","email":"pbarnard@usgs.gov","affiliations":[{"id":520,"text":"Pacific Coastal and Marine Science Center","active":true,"usgs":true}],"preferred":true,"id":790434,"contributorType":{"id":2,"text":"Editors"},"rank":1},{"text":"Jaffe, Bruce E. 0000-0002-8816-5920 bjaffe@usgs.gov","orcid":"https://orcid.org/0000-0002-8816-5920","contributorId":2049,"corporation":false,"usgs":true,"family":"Jaffe","given":"Bruce","email":"bjaffe@usgs.gov","middleInitial":"E.","affiliations":[{"id":520,"text":"Pacific Coastal and Marine Science Center","active":true,"usgs":true},{"id":186,"text":"Coastal and Marine Geology Program","active":true,"usgs":true}],"preferred":true,"id":790435,"contributorType":{"id":2,"text":"Editors"},"rank":2},{"text":"Schoellhamer, David H. 0000-0001-9488-7340 dschoell@usgs.gov","orcid":"https://orcid.org/0000-0001-9488-7340","contributorId":631,"corporation":false,"usgs":true,"family":"Schoellhamer","given":"David H.","email":"dschoell@usgs.gov","affiliations":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"preferred":true,"id":790436,"contributorType":{"id":2,"text":"Editors"},"rank":3}],"authors":[{"text":"Wong, Florence L. 0000-0002-3918-5896 fwong@usgs.gov","orcid":"https://orcid.org/0000-0002-3918-5896","contributorId":1990,"corporation":false,"usgs":true,"family":"Wong","given":"Florence","email":"fwong@usgs.gov","middleInitial":"L.","affiliations":[{"id":520,"text":"Pacific Coastal and Marine Science Center","active":true,"usgs":true}],"preferred":true,"id":485777,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Woodrow, Donald L.","contributorId":88668,"corporation":false,"usgs":true,"family":"Woodrow","given":"Donald L.","affiliations":[],"preferred":false,"id":485778,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"McGann, Mary 0000-0002-3057-2945 mmcgann@usgs.gov","orcid":"https://orcid.org/0000-0002-3057-2945","contributorId":169540,"corporation":false,"usgs":true,"family":"McGann","given":"Mary","email":"mmcgann@usgs.gov","affiliations":[{"id":186,"text":"Coastal and Marine Geology Program","active":true,"usgs":true},{"id":520,"text":"Pacific Coastal and Marine Science Center","active":true,"usgs":true}],"preferred":true,"id":485779,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

In both of the sites, core sediments are generally dominated by hemipelagic muds which are intercalated with turbidite sands. The turbidite sands are usually thin-to-medium bedded and mainly consist of well sorted coarse silt to fine sand. Anomalies in infrared core temperatures and porewater chlorinity data and pressure core measurements indicate that “gas hydrate occurrence zones” (GHOZ) are present about 68–155 mbsf at Site UBGH2-2_2 and 110–155 mbsf at Site UBGH2-6. In both the GHOZ, gas hydrates are preferentially associated with many of the turbidite sands as “pore-filling” type hydrates. The HYBS identified in the cores from Site UBGH2-6 are medium-to-thick bedded particularly in the lower part of the GHOZ and well coincident with significant high excursions in all of the resistivity, density, and velocity logs. Gas-hydrate saturations in the HYBS range from 12% to 79% with an average of 52% based on pore-water chlorinity. In contrast, the HYBS from Site UBGH2-2_2 are usually thin-bedded and show poor correlations with both of the resistivity and velocity logs owing to volume averaging effects of the logging tools on the thin HYBS beds. Gas-hydrate saturations in the HYBS range from 15% to 65% with an average of 37% based on pore-water chlorinity. In both of the sites, large fluctuations in biogenic opal contents have significant effects on the sediment physical properties, resulting in limited usage of gamma ray and density logs in discriminating sand reservoirs.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Marine and Petroleum Geology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/j.marpetgeo.2013.05.007","usgsCitation":"Bahk, J., Kim, G., Chun, J., Kim, J., Lee, J., Ryu, B., Lee, J., Son, B., and Collett, T.S., 2013, Characterization of gas hydrate reservoirs by integration of core and log data in the Ulleung Basin, East Sea: Marine and Petroleum Geology, v. 47, p. 30-42, https://doi.org/10.1016/j.marpetgeo.2013.05.007.","productDescription":"13 p.","startPage":"30","endPage":"42","numberOfPages":"13","ipdsId":"IP-049786","costCenters":[{"id":164,"text":"Central Energy Resources Science Center","active":true,"usgs":true}],"links":[{"id":282021,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":281995,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.marpetgeo.2013.05.007"}],"country":"Korea","otherGeospatial":"East Sea Of Korea;Ulleung Basin","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ 129.0,35.0 ], [ 129.0,38.0 ], [ 133.0,38.0 ], [ 133.0,35.0 ], [ 129.0,35.0 ] ] ] } } ] }","volume":"47","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53cd50b6e4b0b290850f37f3","contributors":{"authors":[{"text":"Bahk, J.-J.","contributorId":99891,"corporation":false,"usgs":true,"family":"Bahk","given":"J.-J.","affiliations":[],"preferred":false,"id":489965,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kim, G.-Y.","contributorId":77454,"corporation":false,"usgs":true,"family":"Kim","given":"G.-Y.","email":"","affiliations":[],"preferred":false,"id":489962,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Chun, J.-H.","contributorId":97421,"corporation":false,"usgs":true,"family":"Chun","given":"J.-H.","email":"","affiliations":[],"preferred":false,"id":489964,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Kim, J.-H.","contributorId":26395,"corporation":false,"usgs":true,"family":"Kim","given":"J.-H.","email":"","affiliations":[],"preferred":false,"id":489959,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Lee, J.Y.","contributorId":20061,"corporation":false,"usgs":true,"family":"Lee","given":"J.Y.","email":"","affiliations":[],"preferred":false,"id":489958,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Ryu, B.-J.","contributorId":59348,"corporation":false,"usgs":true,"family":"Ryu","given":"B.-J.","email":"","affiliations":[],"preferred":false,"id":489960,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Lee, J.-H.","contributorId":77047,"corporation":false,"usgs":true,"family":"Lee","given":"J.-H.","email":"","affiliations":[],"preferred":false,"id":489961,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Son, B.-K.","contributorId":95798,"corporation":false,"usgs":true,"family":"Son","given":"B.-K.","email":"","affiliations":[],"preferred":false,"id":489963,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"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":164,"text":"Central Energy Resources Science Center","active":true,"usgs":true},{"id":171,"text":"Central Mineral and Environmental Resources Science Center","active":true,"usgs":true},{"id":678,"text":"Woods Hole Coastal and Marine Science Center","active":true,"usgs":true},{"id":255,"text":"Energy Resources Program","active":true,"usgs":true}],"preferred":true,"id":489957,"contributorType":{"id":1,"text":"Authors"},"rank":9}]}}

Understanding these interactions could be critically important in the design of climate adaptation strategies, especially because actions taken by other sectors (eg energy, agriculture, transportation) to address climate change may create new ecosystem stresses.</span></p>","language":"English","publisher":"Ecological Society of America","publisherLocation":"Washington, D.C.","doi":"10.1890/120275","usgsCitation":"Staudt, A., Leidner, A.K., Howard, J., Brauman, K., Dukes, J., Hansen, L.J., Paukert, C.P., Sabo, J.L., and Solorzano, L.A., 2013, The added complications of climate change: Understanding and managing biodiversity and ecosystems: Frontiers in Ecology and the Environment, v. 11, no. 9, p. 494-501, https://doi.org/10.1890/120275.","productDescription":"8 p.","startPage":"494","endPage":"501","numberOfPages":"8","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-041500","costCenters":[{"id":198,"text":"Coop Res Unit Atlanta","active":true,"usgs":true},{"id":411,"text":"National Climate Change and Wildlife Science Center","active":true,"usgs":true},{"id":36940,"text":"National Climate Adaptation Science Center","active":true,"usgs":true}],"links":[{"id":486952,"rank":0,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://docs.lib.purdue.edu/fnrpubs/9","text":"External Repository"},{"id":309889,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"11","issue":"9","publishingServiceCenter":{"id":9,"text":"Reston PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"561f7cbce4b03ee62faa8ff8","contributors":{"authors":[{"text":"Staudt, Amanda","contributorId":149223,"corporation":false,"usgs":false,"family":"Staudt","given":"Amanda","email":"","affiliations":[{"id":17681,"text":"National Wildlife Federation, Reston, VA","active":true,"usgs":false}],"preferred":false,"id":577497,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Leidner, Allison K.","contributorId":149222,"corporation":false,"usgs":false,"family":"Leidner","given":"Allison","email":"","middleInitial":"K.","affiliations":[{"id":17680,"text":"AAAS Science & Technology Policy Fellow/NASA","active":true,"usgs":false}],"preferred":false,"id":577496,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Howard, Jennifer","contributorId":149225,"corporation":false,"usgs":false,"family":"Howard","given":"Jennifer","email":"","affiliations":[{"id":17683,"text":"AAAS Science & Technology Policy Fellow/NOAA","active":true,"usgs":false}],"preferred":false,"id":577499,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Brauman, Kate A.","contributorId":149226,"corporation":false,"usgs":false,"family":"Brauman","given":"Kate A.","affiliations":[{"id":17684,"text":"University of Minnesota, Minneapolis, MN","active":true,"usgs":false}],"preferred":false,"id":577500,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Dukes, Jeffrey S.","contributorId":149224,"corporation":false,"usgs":false,"family":"Dukes","given":"Jeffrey S.","affiliations":[{"id":17682,"text":"Dept. of Forestry & Natural Resources & Dept. of Bio, Purdue U","active":true,"usgs":false}],"preferred":false,"id":577498,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Hansen, Lara J.","contributorId":149227,"corporation":false,"usgs":false,"family":"Hansen","given":"Lara","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":577501,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Paukert, Craig P. 0000-0002-9369-8545 cpaukert@usgs.gov","orcid":"https://orcid.org/0000-0002-9369-8545","contributorId":147821,"corporation":false,"usgs":true,"family":"Paukert","given":"Craig","email":"cpaukert@usgs.gov","middleInitial":"P.","affiliations":[{"id":411,"text":"National Climate Change and Wildlife Science Center","active":true,"usgs":true},{"id":198,"text":"Coop Res Unit Atlanta","active":true,"usgs":true}],"preferred":true,"id":577495,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Sabo, John L.","contributorId":39929,"corporation":false,"usgs":true,"family":"Sabo","given":"John","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":577502,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Solorzano, Luis A.","contributorId":149228,"corporation":false,"usgs":false,"family":"Solorzano","given":"Luis","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":577503,"contributorType":{"id":1,"text":"Authors"},"rank":9}]}}

The biota will be spatially distributed according to its response to environmental parameters such as water temperature, salinity, dissolved oxygen, organic carbon content, grain size, and intensity of currents and tidal flow, whereas the presence of anthropogenic and volcanic constituents will reflect proximity to source areas and whether they are fluvially- or aerially-transported. Because each of these constituents have a unique environmental signature, they are a more precise proxy for that source area than the conventional sedimentary process indicators. This San Francisco Bay Coastal System study demonstrates that by applying a multi-proxy approach, the primary sites of sediment transport can be identified. Many of these sites are far from where the constituents originated, showing that sediment transport is widespread in the region.

Here we focus on the San Francisco Bay Coastal System, extending from the lower San Joaquin-Sacramento Delta, through the Bay, and along the adjacent outer Pacific Coast. San Francisco Bay is an urbanized estuary that is impacted by numerous anthropogenic activities common to many large estuaries, including a mining legacy, channel dredging, aggregate mining, reservoirs, freshwater diversion, watershed modifications, urban run-off, ship traffic, exotic species introductions, land reclamation, and wetland restoration. The Golden Gate strait is the sole inlet connecting the Bay to the Pacific Ocean, and serves as the conduit for a tidal flow of ~ 8 x 109 m<sup>3</sup>/day, in addition to the transport of mud, sand, biogenic material, nutrients, and pollutants. Despite this physical, biological and chemical connection, resource management and prior research have often treated the Delta, Bay and adjacent ocean as separate entities, compartmentalized by artificial geographic or political boundaries. The body of work herein presents a comprehensive analysis of system-wide behavior, extending a rich heritage of sediment transport research that dates back to the groundbreaking hydraulic mining-impact research of G.K.

Yet felsic rocks have not been widely identified on Mars, a planet that seems to lack plate tectonics and the associated magmatic processes that can produce evolved siliceous melts on Earth. If Mars once had a feldspar-rich crust that crystallized from an early magma ocean such as that on the Moon, erosion, sedimentation and volcanism have erased any clear surface evidence for widespread felsic materials. Here we report near-infrared spectral evidence from the Compact Reconnaissance Imaging Spectrometer for Mars onboard the Mars Reconnaissance Orbiter for felsic rocks in three geographically disparate locations on Mars. Spectral characteristics resemble those of feldspar-rich lunar anorthosites, but are accompanied by secondary alteration products (clay minerals). Thermodynamic phase equilibrium calculations demonstrate that fractional crystallization of magma compositionally similar to volcanic flows near one of the detection sites can yield residual melts with compositions consistent with our observations. In addition to an origin by significant magma evolution, the presence of felsic materials could also be explained by feldspar enrichment by fluvial weathering processes.

A suite of logging-while-drilling (LWD) logs was acquired at each site. LWD logs from the UBGH2-3A well indicate significant gas hydrate in clay-bearing sediments including several zones with massive gas hydrate with a bulk density less than 1.0 g/m<sup>3</sup> for depths between 5 and 103 m below the sea floor. The UBGH2-3A well was drilled on a seismically identified chimney structure with a mound feature at the sea floor. Average gas hydrate saturations estimated from the isotropic analysis of ring resistivity and P-wave velocity logs are 80 ± 13% and 47 ± 16%, respectively, whereas they are 46 ± 17% and 45 ± 16%, respectively from the anisotropic analysis. Modeling indicates that the upper part of chimney (between 5 and 45 m below sea floor [mbsf]) is characterized by gas hydrate filling near horizontal fractures (7° dip) and the lower part of chimney (between 45 and 103 mbsf) is characterized by gas hydrate filling high angle fractures on the basis of ring resistivity and P-wave velocity. The anisotropic analysis using P40H resistivity (phase shift resistivity at 32 mHz with 40 inch spacing) and the P-wave velocity yields a gas hydrate saturation of 46 ± 15% and 46 ± 15% respectively, similar to those estimated using ring resistivity and P-wave velocity, but with quite different fracture dip angles. Differences in vertical resolution, depth of investigation, and a finite fracture dimension relative to the tool separation appear to contribute to this discrepancy. Forward modeling of anisotropic resistivity and velocity are essential to identify gas hydrate in fractures and to estimate accurate gas hydrate amounts.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Marine and Petroleum Geology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/j.marpetgeo.2012.09.003","usgsCitation":"Lee, M.W., and Collett, T.S., 2013, Characteristics and interpretation of fracture-filled gas hydrate: an example from the Ulleung Basin, East Sea of Korea: Marine and Petroleum Geology, v. 47, p. 168-181, https://doi.org/10.1016/j.marpetgeo.2012.09.003.","productDescription":"14 p.","startPage":"168","endPage":"181","numberOfPages":"14","ipdsId":"IP-038690","costCenters":[{"id":164,"text":"Central Energy Resources Science Center","active":true,"usgs":true}],"links":[{"id":281993,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.marpetgeo.2012.09.003"},{"id":282020,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Korea","otherGeospatial":"East Sea Of Korea;Ulleung Basin","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ 129.0,35.0 ], [ 129.0,38.0 ], [ 133.0,38.0 ], [ 133.0,35.0 ], [ 129.0,35.0 ] ] ] } } ] }","volume":"47","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53cd509ee4b0b290850f3727","contributors":{"authors":[{"text":"Lee, Myung Woong","contributorId":15114,"corporation":false,"usgs":true,"family":"Lee","given":"Myung","email":"","middleInitial":"Woong","affiliations":[],"preferred":false,"id":489947,"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":164,"text":"Central Energy Resources Science Center","active":true,"usgs":true},{"id":255,"text":"Energy Resources Program","active":true,"usgs":true}],"preferred":true,"id":489946,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Accordingly, these models predict that females of related taxa possessing the ancestral state of signalling evolved preference for the male trait in a non-sexual context. We postulated that female preference for the male-released bile alcohol mating pheromone, 3 keto petromyzonol sulfate (3kPZS), of the sea lamprey (Petromyzon marinus) evolved as a result of a receiver bias. In particular, we propose that migratory silver lamprey (Ichthyomyzon unicuspis), a basal member of the Petromyzontidae, evolved a preference for 3kPZS released by stream-resident larvae as a means of identifying productive habitat for offspring. Larval silver lamprey released 3kPZS at rates sufficient to be detected by migratory lampreys. Females responded to 3kPZS by exhibiting upstream movement behaviours relevant in a migratory context, but did not exhibit proximate behaviours important to mate search and spawning. Male silver lamprey did not release 3kPZS at rates sufficient to be detected by females in natural high-volume stream environments. We infer that female silver lamprey cue onto 3kPZS excreted by stream-resident larvae as a mechanism to locate habitat conducive to offspring survival and that males do not signal with 3kPZS. We suggest that this female preference for a male signal in a non-sexual context represents a bias leading to the sexual signalling observed in sea lamprey.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Proceedings of the Royal Society B","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"The Royal Society","doi":"10.1098/rspb.2013.1966","usgsCitation":"Buchinger, T.J., Wang, H., Li, W., and Johnson, N.S., 2013, Evidence for a receiver bias underlying female preference for a male mating pheromone in sea lamprey: Proceedings of the Royal Society B, v. 280, no. 1771, 8 p., https://doi.org/10.1098/rspb.2013.1966.","productDescription":"8 p.","numberOfPages":"8","ipdsId":"IP-051211","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":473459,"rank":0,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://doi.org/10.1098/rspb.2013.1966","text":"External Repository"},{"id":278977,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":278976,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1098/rspb.2013.1966"}],"country":"United States","state":"Michigan","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -90.42,41.7 ], [ -90.42,48.24 ], [ -82.4,48.24 ], [ -82.4,41.7 ], [ -90.42,41.7 ] ] ] } } ] }","volume":"280","issue":"1771","noUsgsAuthors":false,"publicationDate":"2013-11-22","publicationStatus":"PW","scienceBaseUri":"527e586ae4b02d2057dd95de","contributors":{"authors":[{"text":"Buchinger, Tyler J.","contributorId":40508,"corporation":false,"usgs":true,"family":"Buchinger","given":"Tyler","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":483483,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Wang, Huiyong","contributorId":79007,"corporation":false,"usgs":true,"family":"Wang","given":"Huiyong","affiliations":[],"preferred":false,"id":483485,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Li, Weiming","contributorId":65440,"corporation":false,"usgs":true,"family":"Li","given":"Weiming","affiliations":[],"preferred":false,"id":483484,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Johnson, Nicholas S. 0000-0002-7419-6013 njohnson@usgs.gov","orcid":"https://orcid.org/0000-0002-7419-6013","contributorId":597,"corporation":false,"usgs":true,"family":"Johnson","given":"Nicholas","email":"njohnson@usgs.gov","middleInitial":"S.","affiliations":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"preferred":true,"id":483482,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Our capacity to address the rapid and complex changes occurring in these ecosystems can be enhanced by developing an understanding of the environmental factors and ecosystem attributes that determine resilience of native ecosystems to stress and disturbance, and resistance to invasion. Cold desert shrublands occur over strong environmental gradients and exhibit significant differences in resilience and resistance. They provide an excellent opportunity to increase our understanding of these concepts. Herein, we examine a series of linked questions about (a) ecosystem attributes that determine resilience and resistance along environmental gradients, (b) effects of disturbances like livestock grazing and altered fire regimes and of stressors like rapid climate change, rising CO<sub>2</sub>, and N deposition on resilience and resistance, and (c) interacting effects of resilience and resistance on ecosystems with different environmental conditions. We conclude by providing strategies for the use of resilience and resistance concepts in a management context. At ecological site scales, state and transition models are used to illustrate how differences in resilience and resistance influence potential alternative vegetation states, transitions among states, and thresholds. At landscape scales management strategies based on resilience and resistance—protection, prevention, restoration, and monitoring and adaptive management—are used to determine priority management areas and appropriate actions.","language":"English","publisher":"Springer","doi":"10.1007/s10021-013-9725-5","usgsCitation":"Chambers, J., Bradley, B.A., Brown, C.S., D'Antonio, C., Germino, M., Grace, J.B., Hardegree, S., Miller, R., and Pyke, D.A., 2013, Resilience to stress and disturbance, and resistance to Bromus tectorum L. invasion in cold desert shrublands of western North America: Ecosystems, v. 17, no. 2, p. 360-375, https://doi.org/10.1007/s10021-013-9725-5.","productDescription":"16 p.","startPage":"360","endPage":"375","ipdsId":"IP-045776","costCenters":[{"id":290,"text":"Forest and Rangeland Ecosystem Science Center","active":false,"usgs":true},{"id":29789,"text":"John Wesley Powell Center for Analysis and Synthesis","active":true,"usgs":true}],"links":[{"id":473460,"rank":0,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"http://citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.722.5016","text":"External Repository"},{"id":280721,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"17","issue":"2","noUsgsAuthors":false,"publicationDate":"2013-11-14","publicationStatus":"PW","scienceBaseUri":"53cd70a4e4b0b2908510726f","contributors":{"authors":[{"text":"Chambers, Jeanne C.","contributorId":75889,"corporation":false,"usgs":false,"family":"Chambers","given":"Jeanne C.","affiliations":[],"preferred":false,"id":484796,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bradley, Bethany A.","contributorId":40117,"corporation":false,"usgs":true,"family":"Bradley","given":"Bethany","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":484794,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Brown, Cynthia S.","contributorId":86095,"corporation":false,"usgs":true,"family":"Brown","given":"Cynthia","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":484797,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"D'Antonio, Carla","contributorId":25686,"corporation":false,"usgs":true,"family":"D'Antonio","given":"Carla","affiliations":[],"preferred":false,"id":484793,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Germino, Matthew J.","contributorId":50029,"corporation":false,"usgs":true,"family":"Germino","given":"Matthew J.","affiliations":[],"preferred":false,"id":484795,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Grace, James B. 0000-0001-6374-4726 gracej@usgs.gov","orcid":"https://orcid.org/0000-0001-6374-4726","contributorId":884,"corporation":false,"usgs":true,"family":"Grace","given":"James","email":"gracej@usgs.gov","middleInitial":"B.","affiliations":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true},{"id":17705,"text":"Wetland and Aquatic Research Center","active":true,"usgs":true},{"id":455,"text":"National Wetlands Research Center","active":true,"usgs":true}],"preferred":true,"id":484789,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Hardegree, Stuart P.","contributorId":22238,"corporation":false,"usgs":true,"family":"Hardegree","given":"Stuart P.","affiliations":[],"preferred":false,"id":484792,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Miller, Richard F.","contributorId":12964,"corporation":false,"usgs":true,"family":"Miller","given":"Richard F.","affiliations":[],"preferred":false,"id":484791,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Pyke, David A. 0000-0002-4578-8335 david_a_pyke@usgs.gov","orcid":"https://orcid.org/0000-0002-4578-8335","contributorId":3118,"corporation":false,"usgs":true,"family":"Pyke","given":"David","email":"david_a_pyke@usgs.gov","middleInitial":"A.","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":484790,"contributorType":{"id":1,"text":"Authors"},"rank":9}]}}

Coupled with calibration data produced by traditional means, surrogate technologies show considerable promise toward providing the fluvial sediment data needed to increase and bring more consistency to sediment-discharge measurements worldwide.</p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Comprehensive water quality and purification","largerWorkSubtype":{"id":15,"text":"Monograph"},"language":"English","publisher":"Elsevier","doi":"10.1016/B978-0-12-382182-9.00012-8","usgsCitation":"Gray, J.R., and Landers, M.N., 2013, Measuring suspended sediment, chap. 1.10 <i>of</i> Comprehensive water quality and purification, v. 1, p. 157-204, https://doi.org/10.1016/B978-0-12-382182-9.00012-8.","productDescription":"48 p.","startPage":"157","endPage":"204","numberOfPages":"48","ipdsId":"IP-038802","costCenters":[{"id":502,"text":"Office of Surface Water","active":true,"usgs":true}],"links":[{"id":284311,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53cd667ce4b0b29085100c8e","contributors":{"authors":[{"text":"Gray, J.

Begun in 1966, it now is a primary source of information on spatial and temporal patterns of population change for North American birds. We analyze population change for states, provinces, Bird Conservation Regions, and the entire survey within the contiguous United States and southern Canada for 426 species using a hierarchical log-linear model that controls for observer effects in counting. We also map relative abundance and population change for each species using a spatial smoothing of data at the scale of survey routes. We present results in accounts that describe major breeding habitats, migratory status, conservation status, and population trends for each species at several geographic scales. We also present composite results for groups of species categorized by habitats and migratory status. The survey varies greatly among species in percentage of species' range covered and precision of results, but consistent patterns of decline occur among eastern forest, grassland, and aridland obligate birds while generalist bird species are increasing.</p>","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"North American Fauna","largerWorkSubtype":{"id":10,"text":"Journal

Beginning with the development of daily nest survival models, and proceeding through subsequent extensions, the capacity for modeling the effects of hypothesized factors on nest survival has expanded greatly. We extend nest survival models further by introducing an approach to deal with incompletely observed, temporally varying covariates using a hierarchical model. Hierarchical modeling offers a way to separate process and observational components of demographic models to obtain estimates of the parameters of primary interest, and to evaluate structural effects of ecological and management interest. We built a hierarchical model for daily nest survival to analyze nest data from reintroduced whooping cranes (Grus americana) in the Eastern Migratory Population. This reintroduction effort has been beset by poor reproduction, apparently due primarily to nest abandonment by breeding birds. We used the model to assess support for the hypothesis that nest abandonment is caused by harassment from biting insects. We obtained indices of blood-feeding insect populations based on the spatially interpolated counts of insects captured in carbon dioxide traps. However, insect trapping was not conducted daily, and so we had incomplete information on a temporally variable covariate of interest. We therefore supplemented our nest survival model with a parallel model for estimating the values of the missing insect covariates. We used Bayesian model selection to identify the best predictors of daily nest survival. Our results suggest that the black fly Simulium annulus may be negatively affecting nest survival of reintroduced whooping cranes, with decreasing nest survival as abundance of S. annulus increases. The modeling framework we have developed will be applied in the future to a larger data set to evaluate the biting-insect hypothesis and other hypotheses for nesting failure in this reintroduced population; resulting inferences will support ongoing efforts to manage this population via an adaptive management approach. Wider application of our approach offers promise for modeling the effects of other temporally varying, but imperfectly observed covariates on nest survival, including the possibility of modeling temporally varying covariates collected from incubating adults.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecology and Evolution","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Wiley","doi":"10.1002/ece3.822","usgsCitation":"Converse, S., Royle, J., Adler, P.H., Urbanek, R.P., and Barzan, J.A., 2013, A hierarchical nest survival model integrating incomplete temporally varying covariates: Ecology and Evolution, v. 3, no. 13, p. 4439-4447, https://doi.org/10.1002/ece3.822.","productDescription":"9 p.","startPage":"4439","endPage":"4447","numberOfPages":"9","ipdsId":"IP-050325","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":473462,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1002/ece3.822","text":"Publisher Index Page"},{"id":280859,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1002/ece3.822"},{"id":280860,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Wisconsin","otherGeospatial":"Necedah National Wildlife Refuge","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -90.188271,44.039059 ], [ -90.188271,44.098374 ], [ -90.087591,44.098374 ], [ -90.087591,44.039059 ], [ -90.188271,44.039059 ] ] ] } } ] }","volume":"3","issue":"13","noUsgsAuthors":false,"publicationDate":"2013-10-10","publicationStatus":"PW","scienceBaseUri":"53cd49efe4b0b290850ef78c","chorus":{"doi":"10.1002/ece3.822","url":"http://dx.doi.org/10.1002/ece3.822","publisher":"Wiley-Blackwell","authors":"Converse Sarah J., Royle J.

This work presents an objective framework for evaluating competing range performance models. Model selection based on the Akaike’s Information Criterion (AIC) is presented for the type of data collected during a typical human observer and target identification experiment. These methods are then demonstrated on observer responses to both visible and infrared imagery in which one of three maritime targets was placed at various ranges. We compare the performance of a number of different models, including those appearing previously in the literature. We conclude that our model-based approach offers substantial improvements over the traditional approach to inference, including increased precision and the ability to make predictions for some distances other than the specific set for which experimental trials were conducted.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Optical Engineering","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"SPIE","doi":"10.1117/1.OE.52.11.113108","usgsCitation":"Nichols, J., Hines, J., and Nichols, J., 2013, Selecting among competing models of electro-optic, infrared camera system range performance: Optical Engineering, v. 52, no. 11, 9 p., https://doi.org/10.1117/1.OE.52.11.113108.","productDescription":"9 p.","numberOfPages":"9","onlineOnly":"Y","ipdsId":"IP-052140","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":280709,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":279016,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1117/1.OE.52.11.113108"}],"volume":"52","issue":"11","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53cd7254e4b0b290851083f0","contributors":{"authors":[{"text":"Nichols, Jonathan M.","contributorId":45945,"corporation":false,"usgs":true,"family":"Nichols","given":"Jonathan M.","affiliations":[],"preferred":false,"id":486126,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hines, James E. jhines@usgs.gov","contributorId":3506,"corporation":false,"usgs":true,"family":"Hines","given":"James E.","email":"jhines@usgs.gov","affiliations":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"preferred":false,"id":486125,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Nichols, James D. 0000-0002-7631-2890 jnichols@usgs.gov","orcid":"https://orcid.org/0000-0002-7631-2890","contributorId":405,"corporation":false,"usgs":true,"family":"Nichols","given":"James D.","email":"jnichols@usgs.gov","affiliations":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"preferred":false,"id":486124,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

To explore these uncertainties, we constructed 15 megathrust earthquake scenarios using rupture models that supply the initial conditions for tsunami simulations at Bandon, Oregon. Tsunami inundation varies with the amount and distribution of fault slip assigned to rupture models, including models where slip is partitioned to a splay fault in the accretionary wedge and models that vary the updip limit of slip on a buried fault. Constraints on fault slip come from onshore and offshore paleoseismological evidence. We rank each rupture model using a logic tree that evaluates a model’s consistency with geological and geophysical data. The scenarios provide inputs to a hydrodynamic model, SELFE, used to simulate tsunami generation, propagation, and inundation on unstructured grids with <5–15 m resolution in coastal areas. Tsunami simulations delineate the likelihood that Cascadia tsunamis will exceed mapped inundation lines. Maximum wave elevations at the shoreline varied from ∼4 m to 25 m for earthquakes with 9–44 m slip and Mw 8.7–9.2. Simulated tsunami inundation agrees with sparse deposits left by the A.D. 1700 and older tsunamis. Tsunami simulations for large (22–30 m slip) and medium (14–19 m slip) splay fault scenarios encompass 80%–95% of all inundation scenarios and provide reasonable guidelines for land-use planning and coastal development. The maximum tsunami inundation simulated for the greatest splay fault scenario (36–44 m slip) can help to guide development of local tsunami evacuation zones.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Geosphere","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Geological Society of America","doi":"10.1130/GES00899.1","usgsCitation":"Witter, R., Zhang, Y.J., Wang, K., Priest, G., Goldfinger, C., Stimely, L., English, J.T., and Ferro, P.A., 2013, Simulated tsunami inundation for a range of Cascadia megathrust earthquake scenarios at Bandon, Oregon, USA: Geosphere, v. 9, no. 6, p. 1783-1803, https://doi.org/10.1130/GES00899.1.","productDescription":"21 p.","startPage":"1783","endPage":"1803","numberOfPages":"21","ipdsId":"IP-052081","costCenters":[{"id":119,"text":"Alaska Science Center Geology Minerals","active":true,"usgs":true}],"links":[{"id":473463,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1130/ges00899.1","text":"Publisher Index Page"},{"id":280705,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":280704,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1130/GES00899.1"}],"country":"United States","state":"Oregon","city":"Bandon","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -124.5,42.0 ], [ -124.5,44.0 ], [ -124.0,44.0 ], [ -124.0,42.0 ], [ -124.5,42.0 ] ] ] } } ] }","volume":"9","issue":"6","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53cd72cfe4b0b290851088c5","contributors":{"authors":[{"text":"Witter, Robert C. 0000-0002-1721-254X rwitter@usgs.gov","orcid":"https://orcid.org/0000-0002-1721-254X","contributorId":4528,"corporation":false,"usgs":true,"family":"Witter","given":"Robert C.","email":"rwitter@usgs.gov","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":486155,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Zhang, Yinglong J.","contributorId":100281,"corporation":false,"usgs":true,"family":"Zhang","given":"Yinglong","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":486161,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Wang, Kelin","contributorId":15266,"corporation":false,"usgs":true,"family":"Wang","given":"Kelin","affiliations":[],"preferred":false,"id":486156,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Priest, George R.","contributorId":50950,"corporation":false,"usgs":true,"family":"Priest","given":"George R.","affiliations":[],"preferred":false,"id":486157,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Goldfinger, Chris","contributorId":59460,"corporation":false,"usgs":true,"family":"Goldfinger","given":"Chris","affiliations":[],"preferred":false,"id":486159,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Stimely, Laura","contributorId":71092,"corporation":false,"usgs":true,"family":"Stimely","given":"Laura","email":"","affiliations":[],"preferred":false,"id":486160,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"English, John T.","contributorId":100282,"corporation":false,"usgs":true,"family":"English","given":"John","email":"","middleInitial":"T.","affiliations":[],"preferred":false,"id":486162,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Ferro, Paul A.","contributorId":58179,"corporation":false,"usgs":true,"family":"Ferro","given":"Paul","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":486158,"contributorType":{"id":1,"text":"Authors"},"rank":8}]}}
