Data

These data are in two tables relating to a die-off of Common Murres in the north Pacific, 2015-2016. The tables provide: 1) beach survey locations, date, time, distance surveyed (kilometers), and number of Common Murre carcasses observed during surveys conducted along the coastline of Alaska to document the 2015-2016 die-off of Common Murres coincident with the North Pacific marine...

This dataset is three tables with details of samples and aliquots of waterfowl feces deposited in filtered surface water collected from an urban waterbody in Anchorage, Alaska in 2018-2019. Sample vials were submerged underwater in the same waterbody from which the samples were collected and the samples were tested for the presence and viability of influenza A virus. Temperature data and...

This data set is comprised of one table with sampling information and allele sizes for 69 individual Northern Fulmars (Fulmarus glacialis) from Chagulak Island, Alaska and Hafnarey Island, Iceland. Fulmar allele sizes are provided for 10 previously published and 26 novel microsatellite loci. Additionally, allele sizes for the 26 microsatellite loci developed in this study are included...

This data release includes 2 child items with tracking data for Yellow-billed loons, a species that breeds in coastal areas of western and northern Alaska and adjacent regions of Russia and Canada. This species winters along the Pacific coasts of North America and Eurasia. Child Item 1: "Argos Satellite Tracking Data for Yellow-billed Loons (Gavia adamsii) - Processed Data" -- Quality

U.S. Geological Survey researchers conducted time-series ground-penetrating radar (GPR) surveys with a Sensors and Software 500-MHz Pulse Ekko Pro system. This data release contains ground-based (ski and snowmobile) as well as airborne common-offset profiles. All profiles are linked to coincident GPS observations. Additionally, common-midpoint data was collected at specific glacier...

This dataset is four tables with: 1) the body condition and egg counts of Sockeye Salmon captured at several sites along the Pilgrim River 2013-2016, 2) water temperature from 10 automated temperature dataloggers during the summers of 2013-2016, 3) results from an experiment to determine the effect of elevated water temperature on levels of Heat Shock Protein (HSP70) in captive juvenile...

These data are part of the Gulf Watch Alaska (GWA) long-term monitoring program and describe bivalve count and size sampling and observations conducted at intertidal soft-sediment sampling sites in the northern Gulf of Alaska. This dataset consists of five comma separated files (.csv): 1) bivalve taxonomy table, 2) bivalve sampling site table, 3) bivalve count table, 4) bivalve size...

This data release includes two summary geospatial rasters in GeoTIFF format indicating the seasonal Pacific walrus distribution apparent from location tracking obtained from the temporary attachment of Argos transmitter tags to 325 adult Pacific walruses (248 female, 67 male, 10 unknown) between 1987 and 2015. We deployed tags on walruses at locations in the eastern and northern Bering...

This data set describes nuclear microsatellite genotypes derived from ten autosomal loci (Aph8, Aph16, Cmo7, Cmo9, Hhi5, Sfi10, Smo4, Smo6, Smo8, Smo12) and nucleotide sequence data derived from one mitochondrial DNA locus (control region). A total of 262 Spectacled Eiders were examined for this study. Samples were collected at Indigirka and Chaun River Deltas, Russia, and Yukon...

This data release includes tabular surveyed and interpolated elevation data, the processed computational mesh, and model output data used in streambed scour evaluations at selected bridge sites in Alaska, 2016-2017. This is a cooperative project with Alaska Department of Transportation and Public Facilities. The methods of deriving these datasets and using them to calculate scour are...

his data release provides geodetic measurements collected since the mid-1940s to characterize the surface elevation, area, and motion of glaciers studied by the U.S, Geological Survey. The primary glaciers of focus are the Benchmark Glaciers of North America which include Gulkana, Wolverine, and Lemon Creek Glaciers in Alaska, Sperry Glacier in Montana, and South Cascade Glacier in...

This data package includes two tables of data for Bristle-thighed curlews (Numenius tahitiensis) captured 2012-2014 on the James Campbell National Wildlife Refuge O'ahu, Hawaii (21.68 N, 157.95 W). One table provides capture, banding, morphology, and genetic data. The second table provides mark-resight data for estimating the size of the wintering population on Oahu in April of 2014.
