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...
Inshore Catch Data for Capelin (Mallotus villosus) in the Gulf of Alaska, 1996-2017 Inshore Catch Data for Capelin (Mallotus villosus) in the Gulf of Alaska, 1996-2017
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...
Locations Collected 1985-2015 from Female Polar Bears (Ursus maritimus) with Dependent Young Instrumented in the Southern Beaufort Sea with Satellite-linked Transmitters by the USGS Locations Collected 1985-2015 from Female Polar Bears (Ursus maritimus) with Dependent Young Instrumented in the Southern Beaufort Sea with Satellite-linked Transmitters by the USGS
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.
Sea Otter Aerial Survey Data from Glacier Bay National Park and Preserve, 1999-2012 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...
Tracking Data for Tundra Swans (Cygnus columbianus) Tracking Data for Tundra Swans (Cygnus columbianus)
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...
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...
Data from Common Murre Die-off Surveys and Necropsies Following the North Pacific Marine Heatwave, 2015-2016 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...
