This dataset contains a select subset of Argos and GPS locations collected by satellite data collection systems from collared adult female polar bears that were instrumented in the southern Beaufort Sea between 1985-2015.
Accelerometer Data from Collared Female Polar Bears in the Beaufort Sea, 2009-2016 Accelerometer Data from Collared Female Polar Bears in the Beaufort Sea, 2009-2016
This dataset includes accelerometer data collected on collars deployed on female polar bears in the southern Beaufort Sea from 2009-2016. The accelerometer was built in to collars by Telonics, Inc. and provides a single activity value of the number of seconds active per time interval of data collection. Data were collected every 15-30 minutes. GPS and ARGOs locations collected via...
DNA Microsatellite Markers for Northern Fulmar (Fulmaris glacialis) and Cross-species Amplification in Select Seabird Species DNA Microsatellite Markers for Northern Fulmar (Fulmaris glacialis) and Cross-species Amplification in Select Seabird Species
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...
Pacific Walrus Seasonal Distribution from USGS Tracking Data, Chukchi and Bering Seas, 1987-2015 Pacific Walrus Seasonal Distribution from USGS Tracking Data, Chukchi and Bering Seas, 1987-2015
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...
Spectacled Eider (Somateria fischeri) Microsatellite and Mitochondrial DNA Data, 2014-2018, Alaska and Russia Spectacled Eider (Somateria fischeri) Microsatellite and Mitochondrial DNA Data, 2014-2018, Alaska and Russia
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...
Plasmodium Parasite Infection Data from Mosquitoes Collected in South-central Alaska, 2016 Plasmodium Parasite Infection Data from Mosquitoes Collected in South-central Alaska, 2016
This data set includes two tables associated with a study of Plasmodium parasite infection in mosquitoes collected in south-central Alaska during the summer of 2016. The first table contains data regarding mosquito collection from three sites using CO2 baited CDC light traps. Mosquitoes were sorted and pooled according to collection date, genus, and location and subsequently screened for
Blood Parasite Infection Data from Northwestern Crows (Corvus caurinus), Alaska, 2007-2008 Blood Parasite Infection Data from Northwestern Crows (Corvus caurinus), Alaska, 2007-2008
This data set consists of two tables associated with a study of Haemosporidian parasite infection in Northwestern Crows (Corvus caurinus) sampled at six locations throughout southcentral and southeast Alaska in 2007-2008. The first table contains species, location, banding, and morphometric data for all samples. The second table contains results from heamosporidian parasite screening of...
Genetic Data Associated with Avian Keratin Disorder and Poecivirus in Black-capped Chickadees, Alaska, 2001-2017 Genetic Data Associated with Avian Keratin Disorder and Poecivirus in Black-capped Chickadees, Alaska, 2001-2017
This dataset contains results of genetic screening for Poecivirus from samples of black-capped chickadees (BCCH; Poecile atricapillus) with and without clinical signs of avian keratin disorder (AKD). Data include information on detection/non-detection of the virus in tissue collected with buccal swabs, cloacal swabs, blood samples, and fecal samples from up to 124 individuals between...
Gas and heat emission measurements in Norris Geyser Basin, Yellowstone National Park (May-October 2016) Gas and heat emission measurements in Norris Geyser Basin, Yellowstone National Park (May-October 2016)
From 14 May to 6 October 2016 measurements of gas and heat emissions were made at Bison Flat, an acid-sulfate, vapor-dominated area (0.04-km2) of Norris Geyser Basin, Yellowstone National Park, WY. An eddy covariance system measured half-hourly CO2, H2O and sensible and latent heat fluxes, air temperature and pressure, wind speed and direction, soil moisture and rainfall. A Multi-GAS...

Dataset for Alaska Marine Fish Ecology Catalog Dataset for Alaska Marine Fish Ecology Catalog
This collection of GIS layers was prepared for the report Alaska Arctic Marine Fish Ecology Catalog (U.S. Geological Survey Scientific Investigations Report 20165038). The layers display geographic distribution and sampling locations for Arctic marine fish species in the region of United States sectors of the Chukchi and Beaufort Seas. Certain diadromous species (for example, Pacific...
Volcano Monitoring Data Volcano Monitoring Data
Many volcanoes in the U.S. are monitored by arrays of several instruments that detect subtle movements within the earth and changes in gas and water chemistry. The Volcano Hazards Program streams this data to its Volcano Observatories and makes it available on volcano-specific websites.
Alaska Volcano Observatory - Is Ash Falling? Alaska Volcano Observatory - Is Ash Falling?
Reports of ash fall are important to us; we use your observations to assess the character and size of an eruption plume. We report these data to the National Weather Service so they can keep their Ashfall Advisories current. Additionally, reports of NO ashfall during an eruption with expected ashfall are also important to us.
