Data

This dataset contains data from the use of bioelectrical impedance analysis and deuterium injection as methods to estimate the body composition of female polar bears in the southern Beaufort Sea subpopulation. Data are provided on bioelectrical impedance resistance measures, the enrichment level of deuterium oxide that was injected and measured in blood samples, and morphological...

This data package includes 5 child items with data from 9 female polar bears without dependent young in the southern Beaufort Sea in April 2014-2016. Child Item 1: "Doubly-labeled Water, Deuterium Dilution, Body Mass, and Blood Biochemistry Data from Female Polar Bears (Ursus maritimus) in the Southern Beaufort Sea by the USGS in April 2014-2016" Child Item 2: "Resting Metabolic Rates of...

This dataset contains measures of tri-axial acceleration, oxygen consumption, and kinematic measures from two captive polar bears and seven captive grizzly bears resting and walking in a metabolic chamber.

These data consist of larval ( 60 mm) and age-1+ (> 60 mm) Capelin CPUE (Catch per unit effort) from various catch efforts throughout the Gulf of Alaska (GOA) from 1996 – 2017. The dataset contains the following information: fishing gear type, date, time, catch location (latitude and longitude), tow distance, number of capelin caught, and CPUE for capelin greater than and less than 60...

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.

This dataset contains measures of oxygen consumption and stroke frequency from 1 captive subadult female polar bear (166.5 kg) resting in the water (n = 7 sessions) and swimming and diving in a metabolic swim flume with water circulated at approximately 0.6 km/hr during swimming and diving measurements (n = 6 sessions) in September 2017.

The data package "Sea Otter Aerial Survey Data from Glacier Bay National Park and Preserve, 1999-2012"; provides raw data for examining abundance and distribution of northern sea otters (Enhydra lutris kenyoni) in Glacier Bay National Park and Preserve in southeast Alaska, based on data collected during a series of population-wide aerial surveys. The USGS aerial sea otter surveys have...

This data release includes 2 child items with tracking data for Tundra Swans, a species that nests in coastal areas throughout Alaska and winters across a broad area of North America from the Pacific to Atlantic coasts. Child Item 1: "Argos Satellite Tracking Data for Tundra Swans (Cygnus columbianus) - Processed Data" -- Quality-controlled data collected from Argos satellite...

This data release has been SUPERSEDED. No data are provided here. Data from HABs sampling data releases have been appended to U.S. Geological Survey data release: https://doi.org/10.5066/P9MLNP9H. This data set is comprised of two tables with results of algal toxin screening for saxitoxin and domoic acid. We used enzyme-linked immunosorbent assay (ELISA) and high-performance liquid...

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...

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...
