Data for the assessment of the containment pond at Canyon Mine, Arizona, 2019 Data for the assessment of the containment pond at Canyon Mine, Arizona, 2019

These data are comprised of measurements of elements (e.g., uranium, cobalt, nickel, copper, zinc, cadmium, lead, etc.), major anions (chloride, nitrite+nitrate as nitrogen, sulfate, etc.), dissolved organic carbon, and general water quality characteristics in Canyon Mine containment pond water, sediment, vegetaiton and invertebrate samples collected in calendar year 2019.

Chemical and biological data from acute and chronic exposure to sodium nitrate and sodium sulfate for several freshwater organisms in water-only bioassays Chemical and biological data from acute and chronic exposure to sodium nitrate and sodium sulfate for several freshwater organisms in water-only bioassays

The responses (survival, growth, and/or reproduction) of test organisms in six concentrations of toxicants in several test waters with different water quality characteristics. In addition to the individual biological data, chemical, and water quality measurements from each toxicity test are also reported. Test organisms include unionid mussels (Lampsilis siliquoidea, Villosa iris), a...

Polar Bear Microsatellite Data Southern Beaufort Sea 2010-2013 Polar Bear Microsatellite Data Southern Beaufort Sea 2010-2013

This data set provides Polar Bear microsatellite genotypes derived from twenty loci (G1A, G10B, G10C, CXX110, G1D, G10H, G10J, G10L, G10M, MSUT2, MU59, G10P, 145P07, CPH9, CXX20, MU50, MU51, G10X, CXX173, G10U). Samples for microsatellite genetic analysis were collected from polar bears from the southern Beaufort Sea during the spring and fall, 2010-2013. Tissue samples were collected...

Catalogue of Polar Bear (Ursus maritimus) Maternal Den Locations in the Beaufort and Chukchi Seas and Nearby Areas, 1910-2018 Catalogue of Polar Bear (Ursus maritimus) Maternal Den Locations in the Beaufort and Chukchi Seas and Nearby Areas, 1910-2018

This data reports on the approximate locations and methods of discovery of 530 polar bear (Ursus maritimus) maternal dens observed in the Beaufort and Chukchi seas and neighboring areas between 1910 and 2018, and archived partly by the U.S. Geological Survey, Alaska Science Center, and partly by the U.S. Fish and Wildlife Service, Marine Mammals Management, in Anchorage, Alaska. Data...

Measurement Data of Polar Bears Captured in the Chukchi and Southern Beaufort Sea, 1981-2017 Measurement Data of Polar Bears Captured in the Chukchi and Southern Beaufort Sea, 1981-2017

This dataset includes measures collected on polar bears captured in the Chukchi and Beaufort Seas, 1981-2017 by the U.S. Geological Survey and U.S. Fish and Wildlife Service. Data collected include body length, body mass, axillary girth, skull width and tail lengths. Bears were also aged as described in the methods. For some bears, an adipose tissue sample was collected and percent lipid...

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...

USGS Dam Removal Science Database v4.0 USGS Dam Removal Science Database v4.0

This database is the result of an extensive literature search aimed at identifying documents relevant to the emerging field of dam removal science. In total the database contains 214 citations that contain empirical monitoring information associated with 181 different dam removals across the United States and abroad. Data includes publications through 2016 and supplemented with the U.S...

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...

Data on serology results for green turtles with and without fibropapillomatosis from Hawaii and Florida Data on serology results for green turtles with and without fibropapillomatosis from Hawaii and Florida

Fibropapillomatosis (FP) is a tumor disease associated with a herpesvirus (Chelonid herpesvirus 5-ChHV5) that affects mainly green turtles globally. Understanding the epidemiology of FP has been hampered by lack of robust serological assays to monitor exposure to ChHV5. This is due in part to inability to efficiently culture the virus in vitro for neutralization assays. Here, we...

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...
