Although potential tsunami-inundation zones from a Cascadia Subduction Zone (CSZ) earthquake have been delineated, the amount and type of human development in tsunami-prone areas have not been documented. A vulnerability assessment using geographic-information-system tools was conducted to document variations in developed land, human populations, economic assets, and critical facilities relative to CSZ-related tsunami-inundation zones among communities on the open-ocean and Strait of Juan de Fuca coasts of Washington (including Clallam, Jefferson, Grays Harbor, and Pacific Counties). The tsunami-inundation zone in these counties contains 42,972 residents (24 percent of the total study-area population), 24,934 employees (33 percent of the total labor force), and 17,029 daily visitors to coastal Washington State Parks. The tsunami-inundation zone also contains 2,908 businesses that generate $4.6 billion in annual sales volume (31 and 40 percent of study-area totals, respectively) and tax parcels with a combined total value of $4.5 billion (25 percent of the study-area total). Although occupancy values are not known for each site, the tsunami-inundation zone also contains numerous dependent-population facilities (for example, schools and child-day-care centers), public venues (for example, religious organizations), and critical facilities (for example, police stations and public-work facilities). Racial diversity of residents in tsunami-prone areas is low?89 percent of residents are White and 8 percent are American Indian or Alaska Native. Nineteen percent of the residents in the tsunami-inundation zone are over 65 years in age, 30 percent of the residents live on unincorporated county lands, and 35 percent of the households are renter occupied. Employees in the tsunami-inundation zone are largely in businesses related to health care and social assistance, accommodation and food services, and retail trade, reflecting businesses that cater to a growing retiree and tourist population. Community vulnerability, described here by exposure (the amount of assets in tsunami-prone areas) and sensitivity (the relative percentage of assets in tsunami-prone areas) varies among 13 incorporated cities, 7 Indian reservations, and 4 counties. The City of Aberdeen has the highest relative community exposure to tsunamis, whereas the City of Long Beach has the highest relative community sensitivity. Levels of community exposure and sensitivity to tsunamis are found to be related to the amount and percentage, respectively, of a community?s land that is in a tsunami-inundation zone. This report will further the dialogue on societal risk to tsunami hazards in Washington and help risk managers to determine where additional risk-reduction strategies may be needed.","language":"ENGLISH","publisher":"Geological Survey (U.S.)","doi":"10.3133/sir20085004","collaboration":"Prepared in cooperation with the Washington Military Department Emergency Management Division","usgsCitation":"Wood, N., and Soulard, C., 2008, Variations in Community Exposure and Sensitivity to Tsunami Hazards on the Open-Ocean and Strait of Juan de Fuca Coasts of Washington: U.S. Geological Survey Scientific Investigations Report 2008-5004, Report: vi, 34 p.; Data Folder, https://doi.org/10.3133/sir20085004.","productDescription":"Report: vi, 34 p.; Data Folder","onlineOnly":"Y","additionalOnlineFiles":"Y","costCenters":[{"id":293,"text":"Geographic Analysis and Monitoring Program","active":false,"usgs":true}],"links":[{"id":190697,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":10806,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/sir/2008/5004/","linkFileType":{"id":5,"text":"html"}}],"geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -125,47 ], [ -125,49 ], [ -122,49 ], [ -122,47 ], [ -125,47 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a14e4b07f02db602a4f","contributors":{"authors":[{"text":"Wood, Nathan 0000-0002-6060-9729 nwood@usgs.gov","orcid":"https://orcid.org/0000-0002-6060-9729","contributorId":71151,"corporation":false,"usgs":true,"family":"Wood","given":"Nathan","email":"nwood@usgs.gov","affiliations":[{"id":657,"text":"Western Geographic Science Center","active":true,"usgs":true}],"preferred":false,"id":293940,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Soulard, Christopher","contributorId":62687,"corporation":false,"usgs":true,"family":"Soulard","given":"Christopher","affiliations":[],"preferred":false,"id":293939,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Most areas (88%) did not have anomalous ecosystem performance for at least 6 of 8 years between 1996 and 2004. Areas with underperforming EPA (10%) often indicate areas associated with recent fires and areas of possible insect infestation or drying soil related to permafrost degradation. Overperforming areas (2%) occurred in older fire recovery areas where increased deciduous vegetation components are expected.

In their comprehensive study of these earthquakes between 1905 and 1910, Tarr and Martin (1912) showed that these events were accompanied by shoreline changes in Yakutat Bay that ranged from 14.4 m emergence to 2.1 m submergence, uplift of about 1 m at Yakataga 160 km west of Yakutat Bay, and by several zones of surface fissures on land. Although major earthquake faults were not found, Tarr and Martin postulated that the shoreline displacements were caused by vertical movements on a system of concealed steep normal faults and that the fissure zones on ridges were along subsidiary faults. Our geologic studies in the Yakutat Bay region indicate that: (1) the emergent shorelines along Yakutat Bay define a broad upwarp roughly 50 km ́ 30 km that is primarily related to reverse slip on local concealed shallowly dipping thrust faults; (2) the reported subsidence was due largely, or entirely, to nontectonic surficial submergence of unconsolidated deposits; and (3) most, if not all, of the zones of surface fractures related to the 1899 earthquakes are “sackung” that were probably caused by large-scale gravitational slumping of steep slopes, rather than faulting. A small number of early damped seismograms and the vertical uplift data were used to constrain the fault slippage that occurred during the two great earthquakes of 1899. Seismic moments determined from 50-s surface wave amplitudes are ~2 ́x 10<sup>21</sup> N m for these two events, equivalent to <i>M<sub>w</sub></i> 8.1. Uplift determined from raised shorelines within Yakutat Bay can be accounted for by the 10 September event alone, and these data can be fit by ~10- to 20-m dip slippage on three dextral oblique thrust faults that dip ~30° northeast or north. Faulting complexity is also shown by the S-wave seismogram of the 10 September shock, which lasted ~3 min and shows at least three distinct long-period pulses. The large seismic moment of the 4 September event and uplift of ~1 m at Yakataga suggest a 150-km westward extension of faulting along the foothills fold-and-thrust zone. Our reassessment suggests that, although some portions of the complex plate boundary zone ruptured in 1899, regional seismic hazard is currently significant.</p><p>First of all, none of the potentially tsunamigenic offshore thrust faults west of the Pamplona zone slipped in 1899. It is unlikely that all of the onshore thrust faults south of the Chugach–St. Elias thrust fault system did either. Furthermore, more than 100 years of convergence at 48 mm/yr across the region has reloaded faults that slipped in 1899 and added further strains on those that did not. Matters are much less clear for the Yakutat Bay thrusts because although they slipped in 1899, we have no good constraints on the convergence rates across these faults. The most recent pre-1899 uplift event in Yakutat Bay was at least 380 ± 70 years ago.&nbsp;</p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Active tectonics and seismic potential of Alaska","largerWorkSubtype":{"id":15,"text":"Monograph"},"language":"English","publisher":"American Geophysical Union","doi":"10.1029/179GM12","usgsCitation":"Plafker, G., and Thatcher, W.R., 2008, Geological and geophysical evaluation of the mechanisms of the great 1899 Yakutat Bay earthquakes, chap. <i>of</i> Active tectonics and seismic potential of Alaska, p. 215-236, https://doi.org/10.1029/179GM12.","productDescription":"22 p.","startPage":"215","endPage":"236","costCenters":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"links":[{"id":407263,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","otherGeospatial":"Yakutat  Bay, Yakutat block","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -143,\n              57.5\n            ],\n            [\n              -135.5,\n              57.5\n            ],\n            [\n              -135.5,\n              61\n            ],\n            [\n              -143,\n              61\n            ],\n            [\n              -143,\n              57.5\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationDate":"2013-03-19","publicationStatus":"PW","contributors":{"editors":[{"text":"Freymueller, Jeffery T. 0000-0003-0614-0306","orcid":"https://orcid.org/0000-0003-0614-0306","contributorId":244609,"corporation":false,"usgs":false,"family":"Freymueller","given":"Jeffery","email":"","middleInitial":"T.","affiliations":[{"id":6601,"text":"Michigan State University","active":true,"usgs":false}],"preferred":false,"id":852854,"contributorType":{"id":2,"text":"Editors"},"rank":1},{"text":"Haeussler, Peter J. 0000-0002-1503-6247 pheuslr@usgs.gov","orcid":"https://orcid.org/0000-0002-1503-6247","contributorId":503,"corporation":false,"usgs":true,"family":"Haeussler","given":"Peter","email":"pheuslr@usgs.gov","middleInitial":"J.","affiliations":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true},{"id":119,"text":"Alaska Science Center Geology Minerals","active":true,"usgs":true}],"preferred":true,"id":852855,"contributorType":{"id":2,"text":"Editors"},"rank":2},{"text":"Wesson, Robert L. 0000-0003-2702-0012 rwesson@usgs.gov","orcid":"https://orcid.org/0000-0003-2702-0012","contributorId":850,"corporation":false,"usgs":true,"family":"Wesson","given":"Robert","email":"rwesson@usgs.gov","middleInitial":"L.","affiliations":[{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true}],"preferred":true,"id":852856,"contributorType":{"id":2,"text":"Editors"},"rank":3},{"text":"Ekstrom, Goran","contributorId":248378,"corporation":false,"usgs":false,"family":"Ekstrom","given":"Goran","email":"","affiliations":[{"id":49877,"text":"Lamont-Doherty Earth Observatory, Columbia University Earth Institute","active":true,"usgs":false}],"preferred":false,"id":852857,"contributorType":{"id":2,"text":"Editors"},"rank":4}],"authors":[{"text":"Plafker, George","contributorId":3920,"corporation":false,"usgs":false,"family":"Plafker","given":"George","email":"","affiliations":[],"preferred":false,"id":852852,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Thatcher, Wayne R. 0000-0001-6324-545X thatcher@usgs.gov","orcid":"https://orcid.org/0000-0001-6324-545X","contributorId":2599,"corporation":false,"usgs":true,"family":"Thatcher","given":"Wayne","email":"thatcher@usgs.gov","middleInitial":"R.","affiliations":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"preferred":true,"id":852853,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The structural architecture of the subduction zone varies considerably along its length. At the eastern end is a tectonically complex collision zone where the allochthonous Yakutat terrane is moving northwest into mainland Alaska. West of the collision zone a shallow-dipping subducted plate beneath a wide forearc, nearly orthogonal convergence, and a continental-type subduction regime characterizes the eastern part of the subduction zone. In the central part of the subduction zone, convergence becomes increasingly right oblique and the forearc is divided into a series of large clockwise-rotated fault-bounded blocks. Highly oblique convergence and island arc tectonics characterize the western part of the subduction zone. At the extreme western end of the arc, the relative plate motion is nearly pure strike-slip. A series of great subduction earthquakes ruptured most of the 4000-km length of the subduction zone during a period of several decades in the mid 1900s. The majority of these earthquakes broke multiple segments as defined by the large-scale structure of the overriding plate margin and patterns of historic seismicity. Several of these earthquakes generated Pacific-wide tsunamis and significant damage in the southwestern and south-central regions of Alaska. Characterization of previous subduction earthquakes is important in assessing future seismic and tsunami hazards. However, at present such information is available only for the eastern part of the subduction zone. The 1964 Alaska earthquake (M 9.2) ruptured about ~950 km of the plate boundary that encompassed the Kodiak and Prince William Sound (PWS) segments. Within this region, nine paleosubduction earthquakes in the past ~5000 years are recognized on the basis of geologic evidence of sudden land level change and, at some sites, coeval tsunami deposits. Carbon 14-based chronologies indicate recurrence intervals between median calibrated ages for these paleoearthquakes range from 333 to 875 years. The most recent occurred about 489 years ago and broke only the Kodiak segment. During the previous three cycles, both the Kodiak and PWS segments were involved in either multiple-segment ruptures or closely timed pairs of single segment ruptures. evidence for the earlier paleosubduction earthquakes has been found only at sites in the PWS segment. Thus, future work on the paleoseismicity of other segments would by particular valuable in defining the seismic behavior of the subduction zone.</p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Active tectonics and seismic potential of Alaska","largerWorkSubtype":{"id":11,"text":"Bibliography"},"language":"English","publisher":"American Geophysical Union","doi":"10.1029/179GM03","usgsCitation":"Carver, G.A., and Plafker, G., 2008, Paleoseismicity and neotectonics of the Aleutian subduction zone — An overview, chap. <i>of</i> Active tectonics and seismic potential of Alaska, v. 179, p. 43-63, https://doi.org/10.1029/179GM03.","productDescription":"21 p.","startPage":"43","endPage":"63","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true},{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true}],"links":[{"id":407262,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Canada, Russia, United States","state":"Alaska","otherGeospatial":"Aleutian subduction zone","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -179.9,\n              48\n            ],\n            [\n              -130,\n              48\n            ],\n            [\n              -130,\n              72\n            ],\n            [\n              -179.9,\n              72\n            ],\n            [\n              -179.9,\n              48\n            ]\n          ]\n        ]\n      }\n    },\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              160,\n              48\n            ],\n            [\n              179.9,\n              48\n            ],\n            [\n              179.9,\n              72\n            ],\n            [\n              160,\n              72\n            ],\n            [\n              160,\n              48\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"179","noUsgsAuthors":false,"publicationDate":"2013-03-19","publicationStatus":"PW","contributors":{"editors":[{"text":"Freymueller, Jeffery T. 0000-0003-0614-0306","orcid":"https://orcid.org/0000-0003-0614-0306","contributorId":244609,"corporation":false,"usgs":false,"family":"Freymueller","given":"Jeffery","email":"","middleInitial":"T.","affiliations":[{"id":6601,"text":"Michigan State University","active":true,"usgs":false}],"preferred":false,"id":852848,"contributorType":{"id":2,"text":"Editors"},"rank":1},{"text":"Haeussler, Peter J. 0000-0002-1503-6247 pheuslr@usgs.gov","orcid":"https://orcid.org/0000-0002-1503-6247","contributorId":503,"corporation":false,"usgs":true,"family":"Haeussler","given":"Peter","email":"pheuslr@usgs.gov","middleInitial":"J.","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":852849,"contributorType":{"id":2,"text":"Editors"},"rank":2},{"text":"Wesson, Robert L. 0000-0003-2702-0012 rwesson@usgs.gov","orcid":"https://orcid.org/0000-0003-2702-0012","contributorId":850,"corporation":false,"usgs":true,"family":"Wesson","given":"Robert","email":"rwesson@usgs.gov","middleInitial":"L.","affiliations":[{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true}],"preferred":true,"id":852850,"contributorType":{"id":2,"text":"Editors"},"rank":3},{"text":"Ekstrom, Goran","contributorId":248378,"corporation":false,"usgs":false,"family":"Ekstrom","given":"Goran","email":"","affiliations":[{"id":49877,"text":"Lamont-Doherty Earth Observatory, Columbia University Earth Institute","active":true,"usgs":false}],"preferred":false,"id":852851,"contributorType":{"id":2,"text":"Editors"},"rank":4}],"authors":[{"text":"Carver, Gary A.","contributorId":196121,"corporation":false,"usgs":false,"family":"Carver","given":"Gary","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":852846,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Plafker, George","contributorId":3920,"corporation":false,"usgs":false,"family":"Plafker","given":"George","email":"","affiliations":[],"preferred":false,"id":852847,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Whereas the time-independent map treats all sources as statistically independent, the time-dependent analysis is based on calculations of the conditional probability of occurrence for the next 50 years by using a Brownian Passage Time model for the seismic sources judged to be characteristic. We then consider how those probabilities are modified by coseismic and postseismic stress changes resulting from large regional earthquakes occurring from 1938 to 2002. Recombining the time-dependent probabilities with time-independent truncated Gutenberg–Richter and smoothed seismicity sources leads to our time-dependent probabilistic seismic hazard results. We find that when accounting for time dependence without stress changes, earthquake probabilities can be significantly altered, reducing probabilities to near zero or increasing them to several times the time-independent values. In addition, accounting for coseismic stress changes tends to have a local influence on earthquake probabilities, whereas postseismic effects can be far-reaching in both time and space. In sum, however, since we combine time-dependent and time-independent sources, the modification to seismic hazard is relatively minor, increasing or decreasing hazard adjacent to characteristic faults by about 10%. Most cities, located far from characteristic faults, are little affected.</p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Active tectonics and seismic potential of

Dissolved organic carbon (DOC), chromophoric DOM (CDOM), and dissolved lignin phenols were measured across a range of source waters and the seasonal hydrograph. Strong relationships were determined between CDOM and both DOC and lignin phenols, highlighting the potential for deriving detailed spatial and temporal distributions of DOM composition from CDOM monitoring. Maximum concentrations of measured parameters were observed during the spring flush, when DOM had a remarkably high content of aromatic vascular plant material derived from surface soil and litter layers. A larger portion of riverine DOM was attributed to vascular plant sources than previously believed by utilizing representative vegetation leachates and a soil pore water as end‐members. In combination with recent studies highlighting export of young, labile DOM during the spring flush in northern high‐latitude river systems, our results suggest riverine DOM is less degraded and more labile than previously thought with clear ramifications for its biomineralization or photo‐oxidation in marine environments.</p></div>","language":"English","publisher":"AGU","doi":"10.1029/2008GB003231","usgsCitation":"Spencer, R., Aiken, G., Wickland, K.P., Striegl, R., and Hernes, P.J., 2008, Seasonal and spatial variability in dissolved organic matter quantity and composition from the Yukon River basin, Alaska: Global Biogeochemical Cycles, v. 22, no. 4, GB4002, https://doi.org/10.1029/2008GB003231.","productDescription":"GB4002","costCenters":[{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":476628,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1029/2008gb003231","text":"Publisher Index Page"},{"id":358595,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"22","issue":"4","noUsgsAuthors":false,"publicationDate":"2008-10-03","publicationStatus":"PW","scienceBaseUri":"5c10d476e4b034bf6a7fa242","contributors":{"authors":[{"text":"Spencer, R.G.M.","contributorId":60361,"corporation":false,"usgs":true,"family":"Spencer","given":"R.G.M.","email":"","affiliations":[],"preferred":false,"id":749164,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Aiken, George 0000-0001-8454-0984","orcid":"https://orcid.org/0000-0001-8454-0984","contributorId":208803,"corporation":false,"usgs":true,"family":"Aiken","given":"George","affiliations":[],"preferred":true,"id":749165,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Wickland, Kimberly P. 0000-0002-6400-0590 kpwick@usgs.gov","orcid":"https://orcid.org/0000-0002-6400-0590","contributorId":1835,"corporation":false,"usgs":true,"family":"Wickland","given":"Kimberly","email":"kpwick@usgs.gov","middleInitial":"P.","affiliations":[{"id":5044,"text":"National Research Program - Central Branch","active":true,"usgs":true},{"id":36183,"text":"Hydro-Ecological Interactions Branch","active":true,"usgs":true},{"id":37277,"text":"WMA - Earth System Processes Division","active":true,"usgs":true}],"preferred":true,"id":749166,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Striegl, Rob","contributorId":208472,"corporation":false,"usgs":true,"family":"Striegl","given":"Rob","affiliations":[{"id":5044,"text":"National Research Program - Central Branch","active":true,"usgs":true}],"preferred":true,"id":749167,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Hernes, Peter J.","contributorId":85311,"corporation":false,"usgs":true,"family":"Hernes","given":"Peter","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":749168,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

We use offshore multichannel seismic reflection data and oil-well stratigraphy to evaluate whether local geologic structures are compatible with boundaries of either tectonic block and with the relative motion expected across the block boundaries. Our main conclusion is that a block boundary does not extend southwestward the entire length of Shelikof Strait, as was proposed for one of the blocks. Furthermore, below southern Cook Inlet, no high-strain extensional structures that might be related to either proposed boundary are evident. Small normal faults below southern Cook Inlet could have been caused by block rotation, but they represent only minor strain. One way to explain the lack of larger structures is that the rotation began recently so that indicative boundary structures have not yet formed. Alternatively, deformation associated with the block boundaries could be distributed through onshore areas.</p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Active tectonics and seismic potential of Alaska","largerWorkSubtype":{"id":15,"text":"Monograph"},"language":"English","publisher":"American Geophysical Union","doi":"10.1029/179GM16","usgsCitation":"Fisher, M.A., Sliter, R.W., and Wong, F.L., 2008, Does a boundary of the Wrangell Block extend through southern Cook Inlet and Shelikof Strait, Alaska?, chap. <i>of</i> Active tectonics and seismic potential of Alaska, v. 179, p. 285-295, https://doi.org/10.1029/179GM16.","productDescription":"9 p.","startPage":"285","endPage":"295","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true},{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true},{"id":520,"text":"Pacific Coastal and Marine Science Center","active":true,"usgs":true}],"links":[{"id":407260,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.er.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","otherGeospatial":"Shelikof Strait, southern Cook Inlet, Wrangell Block","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -156,\n              60\n            ],\n            [\n              -156,\n              57\n            ],\n            [\n              -152,\n              57\n            ],\n            [\n              -152,\n              60\n            ],\n            [\n              -156,\n              60\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"179","noUsgsAuthors":false,"publicationDate":"2013-03-19","publicationStatus":"PW","contributors":{"editors":[{"text":"Freymueller, Jeffery T. 0000-0003-0614-0306","orcid":"https://orcid.org/0000-0003-0614-0306","contributorId":244609,"corporation":false,"usgs":false,"family":"Freymueller","given":"Jeffery","email":"","middleInitial":"T.","affiliations":[{"id":6601,"text":"Michigan State University","active":true,"usgs":false}],"preferred":false,"id":852833,"contributorType":{"id":2,"text":"Editors"},"rank":1},{"text":"Haeussler, Peter J. 0000-0002-1503-6247 pheuslr@usgs.gov","orcid":"https://orcid.org/0000-0002-1503-6247","contributorId":503,"corporation":false,"usgs":true,"family":"Haeussler","given":"Peter","email":"pheuslr@usgs.gov","middleInitial":"J.","affiliations":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true},{"id":119,"text":"Alaska Science Center Geology Minerals","active":true,"usgs":true}],"preferred":true,"id":852834,"contributorType":{"id":2,"text":"Editors"},"rank":2},{"text":"Wesson, Robert L. 0000-0003-2702-0012 rwesson@usgs.gov","orcid":"https://orcid.org/0000-0003-2702-0012","contributorId":850,"corporation":false,"usgs":true,"family":"Wesson","given":"Robert","email":"rwesson@usgs.gov","middleInitial":"L.","affiliations":[{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true}],"preferred":true,"id":852835,"contributorType":{"id":2,"text":"Editors"},"rank":3},{"text":"Ekstrom, Goran","contributorId":248378,"corporation":false,"usgs":false,"family":"Ekstrom","given":"Goran","email":"","affiliations":[{"id":49877,"text":"Lamont-Doherty Earth Observatory, Columbia University Earth Institute","active":true,"usgs":false}],"preferred":false,"id":852836,"contributorType":{"id":2,"text":"Editors"},"rank":4}],"authors":[{"text":"Fisher, Michael A. mfisher@usgs.gov","contributorId":1991,"corporation":false,"usgs":true,"family":"Fisher","given":"Michael","email":"mfisher@usgs.gov","middleInitial":"A.","affiliations":[],"preferred":true,"id":852830,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Sliter, Ray W. 0000-0003-0337-3454 rsliter@usgs.gov","orcid":"https://orcid.org/0000-0003-0337-3454","contributorId":1992,"corporation":false,"usgs":true,"family":"Sliter","given":"Ray","email":"rsliter@usgs.gov","middleInitial":"W.","affiliations":[{"id":520,"text":"Pacific Coastal and Marine Science Center","active":true,"usgs":true}],"preferred":true,"id":852831,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"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":852832,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Recent developments in infrared imagery and its integration with digital photography could allow substantially larger areas to be surveyed and more accurate enumeration of individuals, thereby solving major problems with previous survey methods. We conducted a trial survey in April 2003 to estimate the number of Pacific walruses (Odobenus rosmarus divergens) hauled out on sea ice around St. Lawrence Island, Alaska. The survey used high altitude infrared imagery to detect groups of walruses on strip transects. Low altitude digital photography was used to determine the number of walruses in a sample of detected groups and calibrate the infrared imagery for estimating the total number of walruses. We propose a survey design incorporating this approach with satellite radio telemetry to estimate the proportion of the population in the water and additional low-level flights to estimate the proportion of the hauled-out population in groups too small to be detected in the infrared imagery.

Nest survival is one component of recruitment, and a female's chance of reproductive success increases with her ability to choose an appropriate nesting strategy. We estimated variation in daily nest survival of king eiders at 2 sites, Teshekpuk and Kuparuk, Alaska, USA, 2002-2005. We evaluated both a priori and exploratory competing models of nest survival that considered importance of nest concealment, seclusion, and incubation constancy as strategies to avoid 2 primary egg predators, avian (Larus spp., Stercorarius spp., and Corvus corax) and fox (Alopex lagopus). We used generalized nonlinear techniques to examine factors affecting nest survival rates and information-theoretic approaches to select among competing models. Estimated nest survival, accounting for a nest visitation effect, varied considerably across sites and years (0.21-0.57); however, given our small sample size, much of this variation maybe attributable to sampling variation (??process = 0.007, 95% CI: 0.003-0.070). Nest survival was higher at Kuparuk than Teshekpuk in all years; however, due to the correlative nature of our data, we cannot determine the underlying causes with any certainty. We found mixed support for the concealed breeding strategy, females derived no benefit from nesting in areas with more willow (Salix spp.; measure of concealment) except that the observer effect diminished as willow cover increased. We suggest these patterns are due to conflicting predation pressures. Nest survival was not higher on islands (measure of seclusion) or with increased incubation constancy but was higher post-fox removal, indicating that predator control on breeding grounds could be a viable management option. Nest survival was negatively affected by our nest visitations, most likely by exposing the nest to avian scavengers. We recommend precautions be taken to limit the effects of nest visits in future studies and to consider them as a possible negative bias in estimated nest survival. Future models of the impacts of development within the breeding grounds of king eider should consider the influence of humans in the vicinity of nests.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Wildlife Management","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.2193/2007-345","issn":"00225","usgsCitation":"Bentzen, R., Powell, A., and Suydam, R., 2008, Factors influencing nesting success of king eiders on northern Alaska's Coastal Plain: Journal of Wildlife Management, v. 72, no. 8, p. 1781-1789, https://doi.org/10.2193/2007-345.","startPage":"1781","endPage":"1789","numberOfPages":"9","costCenters":[],"links":[{"id":214373,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.2193/2007-345"},{"id":242096,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"72","issue":"8","noUsgsAuthors":false,"publicationDate":"2010-12-13","publicationStatus":"PW","scienceBaseUri":"505a0ec7e4b0c8380cd5360b","contributors":{"authors":[{"text":"Bentzen, R.L.","contributorId":42443,"corporation":false,"usgs":true,"family":"Bentzen","given":"R.L.","email":"","affiliations":[],"preferred":false,"id":442077,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Powell, A.N.","contributorId":66194,"corporation":false,"usgs":true,"family":"Powell","given":"A.N.","email":"","affiliations":[],"preferred":false,"id":442078,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Suydam, R.S.","contributorId":74213,"corporation":false,"usgs":true,"family":"Suydam","given":"R.S.","email":"","affiliations":[],"preferred":false,"id":442079,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

The shift from sedge to Sphagnum, and a decrease in the detrended tree-ring width index of black spruce trees adjacent to the collapse coincided with an increase in the growing season temperature record from Fairbanks. This concurrent wetland succession and reduced growth of black spruce trees indicates a step-wise ecosystem-level response to a change in regional climate. In 2001, fire was observed coincident with permafrost collapse and resulted in lateral expansion of the peatland. These observations and the peat profile suggest that future warming and/or increased fire disturbance could promote permafrost degradation, peatland expansion, and increase carbon storage across this landscape; however, the development of drought conditions could reduce the success of both black spruce and Sphagnum, and potentially decrease the long-term ecosystem carbon storage.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Biogeosciences","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"European Geosciences Union","doi":"10.5194/bg-5-1273-2008","issn":"17264170","usgsCitation":"Myers-Smith, I., Harden, J., Wilmking, M., Fuller, C.C., McGuire, A., and Chapin, F.S., 2008, Wetland succession in a permafrost collapse: Interactions between fire and thermokarst: Biogeosciences, v. 5, no. 5, p. 1273-1286, https://doi.org/10.5194/bg-5-1273-2008.","startPage":"1273","endPage":"1286","numberOfPages":"14","costCenters":[],"links":[{"id":476823,"rank":1,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.5194/bg-5-1273-2008","text":"Publisher Index Page"},{"id":266033,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.5194/bg-5-1273-2008"},{"id":218623,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"5","issue":"5","noUsgsAuthors":false,"publicationDate":"2008-09-05","publicationStatus":"PW","scienceBaseUri":"505bd021e4b08c986b32ecba","contributors":{"authors":[{"text":"Myers-Smith, I.

The Yukon River Basin (YRB), which encompasses 330,000 square miles in northwestern Canada and central Alaska (fig. 1), is one of the largest and most diverse ecosystems in North America. The Yukon River is more than 1,800 miles long and is one of the last great uncontrolled rivers in the world, and is essential to the eastern Bering Sea and Chukchi Sea ecosystems, providing freshwater runoff, sediments, and nutrients (Brabets and others, 2000). Despite its remoteness, recent studies (Hinzman and others, 2005; Walvoord and Striegl, 2007) indicate the YRB is changing. These changes likely are in response to a warming trend in air temperature of 1.7i??C from 1951 to 2001 (Hartmann and Wendler, 2005). As a result of this warming trend, permafrost is thawing in the YRB, ice breakup occurs earlier on the main stem of the Yukon River and its tributaries, and timing of streamflow and movement of carbon and sediment through the basin is changing (Hinzman and others, 2005; Walvoord and Striegl, 2007). One of the most striking characteristics in the YRB is its seasonality. In the YRB, more than 75 percent of the annual streamflow runoff occurs during a five month period, May through September. This is important because streamflow determines when, where, and how much of a particular constituent will be transported. As an example, more than 95 percent of all sediment transported during an average year also occurs during this period (Brabets and others, 2000). During the other 7 months, streamflow, concentrations of sediment and other water-quality constituents are low and little or no sediment transport occurs in the Yukon River and its tributaries. Streamflow and water-quality data have been collected at more than 50 sites in the YRB (Dornblaser and Halm, 2006; Halm and Dornblaser, 2007). Five sites have been sampled more than 30 times and others have been sampled twice during peak- and low-flow conditions as part of synoptic sampling campaigns. Although the synoptic data do not provide a complete picture of water quality of a particular river through the year, the data do provide a snapshot of water-quality conditions at a particular time of year. Two constituents of interest are suspended sediment and dissolved organic carbon (DOC). Suspended sediment is important because elevated concentrations can adversely affect aquatic life by obstructing fish gills, covering fish spawning sites, and altering habitat of benthic organisms. Metals and organic contaminants also tend to adsorb onto fine-grained sediment. Permafrost thawing has major implications for the carbon cycle. It is critical to understand the processes related to the transport of DOC to surface waters and how long-term climatic changes may alter these processes (Schuster and others, 2004).</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/fs20083005","usgsCitation":"Brabets, T.P., and Schuster, P.F., 2008, Transport of water, carbon, and sediment through the Yukon River Basin: U.S. Geological Survey Fact Sheet 2008-3005, 4 p., https://doi.org/10.3133/fs20083005.","productDescription":"4 p.","startPage":"0","endPage":"4","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"links":[{"id":125661,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/fs_2008_3005.jpg"},{"id":367591,"rank":3,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/fs/2008/3005/pdf/fs20083005.pdf"},{"id":10771,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/fs/2008/3005/","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"Alaska","otherGeospatial":"Yukon River Basin","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -166,59 ], [ -166,70 ], [ -129,70 ], [ -129,59 ], [ -166,59 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a4ce4b07f02db626bdf","contributors":{"authors":[{"text":"Brabets, Timothy P. tbrabets@usgs.gov","contributorId":2087,"corporation":false,"usgs":true,"family":"Brabets","given":"Timothy","email":"tbrabets@usgs.gov","middleInitial":"P.","affiliations":[],"preferred":true,"id":293854,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Schuster, Paul F. 0000-0002-8314-1372 pschuste@usgs.gov","orcid":"https://orcid.org/0000-0002-8314-1372","contributorId":1360,"corporation":false,"usgs":true,"family":"Schuster","given":"Paul","email":"pschuste@usgs.gov","middleInitial":"F.","affiliations":[{"id":438,"text":"National Research Program - Western Branch","active":true,"usgs":true},{"id":5044,"text":"National Research Program - Central Branch","active":true,"usgs":true}],"preferred":true,"id":293853,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Total concentrations of OTs in sea otters from California ranged from 34 to 4100 ng/g on a wet weight basis. The order of concentrations of OTs in sea otters was total butyltins ??? total octyltins ??? total phenyltins. Elevated concentrations of butyltins (BTs) were found in some otters classified under 'infectious-disease' mortality category. Concentrations of BTs in few of these otters were close to or above the threshold levels for adverse health effects. Total butyltin concentrations decreased significantly in the livers of California sea otters since the 1990s. Based on the concentrations of organotins in sea otters collected from 1992 to 2002, the half-lives of tributyltin and total butyltins in sea otters were estimated to be approximately three years. ?? 2008 Elsevier Ltd.

The range in concentrations has not been explained fully by bear age, sex, condition, location, or reproductive status. Dietary pathways expose polar bears to a variety of contaminant profiles and concentrations. Prey range from lower trophic level bowhead whales (Balaena mysticetus L., 1758), one of the least contaminated marine mammals, to highly contaminated upper trophic level ringed seals (Phoca hispida (Schreber, 1775)). We used ??15N and ??13C signatures to estimate the trophic status of 42 polar bears sampled along Alaska's Beaufort Sea coast to determine the relationship between organochlorine concentration and trophic level. The ?? 15N values in the cellular portions of blood ranged from 18.2% to 20.7%. We found strong positive relationships between concentrations of the most recalcitrant polychlorinated biphenyls (PCBs) and ??15N values in models incorporating age, lipid content, and ??13C value. Specifically these models accounted for 67% and 76% of the variation in PCB153 and oxychlordane concentration in male polar bears and 85% and 93% in females, respectively. These results are strong indicators of variation in diet and biomagnification of organochlorines among polar bears related to their sex, age, and trophic position. ?? 2008 NRC.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Canadian Journal of Zoology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1139/Z07-124","issn":"00084301","usgsCitation":"Bentzen, T., Follmann, E.H., Amstrup, S.C., York, G., Wooller, M.J., Muir, D., and O'Hara, T., 2008, Dietary biomagnification of organochlorine contaminants in Alaskan polar bears: Canadian Journal of Zoology, v. 86, no. 3, p. 177-191, https://doi.org/10.1139/Z07-124.","startPage":"177","endPage":"191","numberOfPages":"15","costCenters":[],"links":[{"id":214738,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1139/Z07-124"},{"id":242488,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"86","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a00dbe4b0c8380cd4f966","contributors":{"authors":[{"text":"Bentzen, T.W.","contributorId":97324,"corporation":false,"usgs":true,"family":"Bentzen","given":"T.W.","email":"","affiliations":[],"preferred":false,"id":433583,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Follmann, Erich H.","contributorId":24828,"corporation":false,"usgs":false,"family":"Follmann","given":"Erich","email":"","middleInitial":"H.","affiliations":[],"preferred":false,"id":433579,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Amstrup, Steven C.","contributorId":67034,"corporation":false,"usgs":false,"family":"Amstrup","given":"Steven","email":"","middleInitial":"C.","affiliations":[{"id":13182,"text":"Polar Bears International","active":true,"usgs":false}],"preferred":false,"id":433581,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"York, G.S.","contributorId":103857,"corporation":false,"usgs":true,"family":"York","given":"G.S.","email":"","affiliations":[],"preferred":false,"id":433584,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Wooller, M.

Smolt-to-adult survival of pink salmon O. gorbuscha returning to Prince William Sound was lower than average for juveniles that entered marine waters in 2001 and 2003 (3% in both years), and high for those that entered the ocean in 2002 (9%) and 2004 (8%). We used circulus patterns from scales to determine how the early marine growth of juvenile pink salmon differed (1) seasonally during May-October, the period hypothesized to be critical for survival; (2) between years of low and high survival; and (3) between hatchery and wild fish. Juvenile pink salmon exhibited larger average size, migrated onto the continental shelf and out of the sampling area more quickly, and survived better during 2002 and 2004 than during 2001 and 2003. Pink salmon were consistently larger throughout the summer and early fall during 2002 and 2004 than during 2001 and 2003, indicating that larger, faster-growing juveniles experienced higher survival. Wild juvenile pink salmon were larger than hatchery fish during low-survival years, but no difference was observed during high-survival years. Differences in size among years were determined by some combination of growing conditions and early mortality, the strength of which could vary significantly among years. ??

In the 1980s and early 1990s, we conducted a geological and geophysical investigation, known as the Trans-Alaska Crustal Transect (TACT), along a 1350-km-long corridor from the Aleutian Trench to the Arctic coast. The most distinctive crustal structures and the deepest Moho along the transect are located near the Pacific and Arctic margins. Near the Pacific margin, we infer a stack of tectonically underplated oceanic layers interpreted as remnants of the extinct Kula (or Resurrection) plate. Continental Moho just north of this underplated stack is more than 55 km deep. Near the Arctic margin, the Brooks Range is underlain by large-scale duplex structures that overlie a tectonic wedge of North Slope crust and mantle. There, the Moho has been depressed to nearly 50 km depth. In contrast, the Moho of central Alaska is on average 32 km deep. In the Paleogene, tectonic underplating of Kula (or Resurrection) plate fragments overlapped in time with duplexing in the Brooks Range. Possible tectonic models linking these two regions include flat-slab subduction and an orogenic-float model. In the Neogene, the tectonics of the accreting Yakutat terrane have differed across a newly interpreted tear in the subducting Pacific oceanic lithosphere. East of the tear, Pacific oceanic lithosphere subducts steeply and alone beneath the Wrangell volcanoes, because the overlying Yakutat terrane has been left behind as underplated rocks beneath the rising St. Elias Range, in the coastal region. West of the tear, the Yakutat terrane and Pacific oceanic lithosphere subduct together at a gentle angle, and this thickened package inhibits volcanism.&nbsp;</p>","largerWorkTitle":"","language":"English","publisher":"Geological Society of America","doi":"10.1130/G24257A.1","issn":"00917613","usgsCitation":"Fuis, G.S., Moore, T., Plafker, G., Brocher, T., Fisher, M.A., Mooney, W.D., Nokleberg, W., Page, R., Beaudoin, B.C., Christensen, N., Levander, A.R., Lutter, W.J., Saltus, R.W., and Ruppert, N., 2008, Trans-Alaska Crustal Transect and continental evolution involving subduction underplating and synchronous foreland thrusting: Geology, v. 36, no. 3, p. 267-270, https://doi.org/10.1130/G24257A.1.","productDescription":"4 p.","startPage":"267","endPage":"270","numberOfPages":"4","costCenters":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"links":[{"id":242383,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -154.86328125,\n              58.17070248348609\n            ],\n            [\n              -133.59375,\n              58.17070248348609\n            ],\n            [\n              -133.59375,\n              65.5129625532949\n            ],\n            [\n              -154.86328125,\n              65.5129625532949\n            ],\n            [\n              -154.86328125,\n              58.17070248348609\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"36","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bb6b9e4b08c986b326e39","contributors":{"authors":[{"text":"Fuis, Gary S. 0000-0002-3078-1544 fuis@usgs.gov","orcid":"https://orcid.org/0000-0002-3078-1544","contributorId":2639,"corporation":false,"usgs":true,"family":"Fuis","given":"Gary","email":"fuis@usgs.gov","middleInitial":"S.","affiliations":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"preferred":true,"id":433553,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Moore, Thomas E. 0000-0002-0878-0457","orcid":"https://orcid.org/0000-0002-0878-0457","contributorId":85592,"corporation":false,"usgs":true,"family":"Moore","given":"Thomas E.","affiliations":[],"preferred":false,"id":433555,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Plafker, George 0000-0003-3972-0390","orcid":"https://orcid.org/0000-0003-3972-0390","contributorId":36603,"corporation":false,"usgs":true,"family":"Plafker","given":"George","affiliations":[],"preferred":false,"id":433547,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Brocher, T.M. 0000-0002-9740-839X","orcid":"https://orcid.org/0000-0002-9740-839X","contributorId":69994,"corporation":false,"usgs":true,"family":"Brocher","given":"T.M.","affiliations":[],"preferred":false,"id":433551,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Fisher, M.
