Metabolic Rate, Body Composition, Foraging Success, Behavior, and GPS Locations of Female Polar Bears (Ursus maritimus), Beaufort Sea, Spring, 2014-2016 and Resting Energetics of an Adult Female Polar Bear

This data release comprises 4 datasets used to measure the field metabolic rate, body composition, foraging success, behavior, and movement patterns of 9 female polar bears on the sea ice of the Beaufort Sea in April, 2014-2016 as well as 1 dataset used to measure the energetic cost of resting in an adult female polar bear at the San Diego Zoo, San Diego, CA. Wild bears were dosed with and had the

Energetic Costs of Locomotion in Bears

Oxygen consumption and kinematic measurement data and tri-axial acceleration measurement data from 2 captive polar bears and 7 captive grizzly bears resting and walking

Inshore Catch Data for Capelin (Mallotus villosus) in the Gulf of Alaska 1996-2017

These data consist of larval (less than 60 mm) and age-1+ (greater than 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

Measures of oxygen consumption and stroke frequency of a captive subadult polar bear (Ursus maritimus) while resting in water and swimming and diving in a metabolic water flume, Oregon Zoo, 2017

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.

Sea Otter Aerial Survey Data from Glacier Bay National Park and Preserve, 1999-2012

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 been complete

Tracking Data for Tundra Swan (Cygnus columbianus)

This metadata document describes the data contained in the "rawData" folder of this data package. This data package contains all data collected by the Argos System from 50 satellite transmitters attached to Tundra Swans on their breeding range in arctic and western Alaska, 2008. Five data files are included in the "rawData" folder of this data package. Two data files (with identical content) conta

Data Associated With Algal Toxin Testing of Common Murres (Uria aalge) and Forage Fish in Alaska, 2015-2017

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 chromatography (HPLC) to screen seabirds, forage fish, and marine invertebrates from the Gulf of Alaska, 2015-2017.

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 collars were use

Data from Common Murre Die-off Surveys and Necropsies Following the North Pacific Marine Heatwave, 2015-2016

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 heatwave, and 2

Influenza A Virus Persistence Data from an Urban Wetland in Anchorage, Alaska, 2018-2019

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 water che

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 for Arctic T
