Data

This dataset describes reactivity of sera collected from polar bears inhabiting Alaska to various influenza A antigens to assess prior exposure to H5 clade 2.3.4.4b highly pathogenic avian influenza viruses (HPAIVs).

This data package includes seven tables with data about the composition, distribution, relative abundance, seasonal availability, energy density, morphometrics, taxonomy, and stable isotope values of benthic fish and invertebrates, as well as oceanographic data within the proposed oil and gas lease sale area in lower Cook Inlet, Alaska.

This data release contains tabular data and photographs from avian surveys of shorebird, predator birds, and other bird species in western Alaska between 1988 and 2012. The data package includes seven tables: 1) characteristics of bird survey sites, 2) habitat classification at survey sites, 3) detections of all birds at survey sites, 4) detections and behaviors of shorebirds and...

This dataset consists of a single table of feeding trial data collected from 18 polar bears at zoos in the United States and Europe. Bears were fed meat on or off bone, fat, and ground meat. The duration of feeding, amount of food consumed, and number of bites taken were recorded.

This dataset consists of a single table of data collected from video of polar bears feeding at remains of subsistence harvested bowhead whales on Barter Island. The table includes focal observations of individual bears to record the type of whale tissue consumed (blubber, muscle, etc.) and the number of bites taken by bears from food items over periods of 30 seconds to 12 minutes.

These data contain two tables of summarized activity sensor and location data of 29 polar bears that fed at bowhead whale remains left by subsistence hunters. Remains occurred on Barter and Cross Islands on the northern coast of Alaska. Activity sensor data were collected from 6 bears using tri-axial accelerometers. The data are presented in two tables providing a summary of all...

GPS collar location data were collected as part of a study on migratory, barren-ground caribou (Rangifer tarandus) in the Central Arctic herd of Alaska. Data were collected in collaboration with Alaska Department of Fish and Game (ADFG). Because ADFG has a statute (16.05.815) restricting the public release of specific animal locations for 25 years, we are only providing metadata about...

This dataset consists of three tables containing sample information and uranium-lead (U-Pb) isotopic data and U-Pb ages measured in zircon collected from igneous rocks in Alaska. The samples were collected between 2019 and 2023 and analyzed by laser ablation inductively-coupled plasma mass spectrometry (LA-ICP-MS) by GeoSep Services. The dataset includes 412 analyses across 13 samples...

This data package includes two child items with data from montane-nesting bird surveys in Katmai National Park and Preserve and Lake Clark National Park and Preserve, Alaska during 2004 through 2006. Child Item One: "Data and Photographs from the Inventory of Montane-nesting Birds in Katmai National Park and Preserve and Lake Clark National Park and Preserve, Alaska". The data include (1...

This data release provides continuous water quality measurements from five sites in different landscapes within the Nellie Juan River Basin, Alaska. For each site there are six to seven tables of water quality data: dissolved oxygen (DO), fluorescent dissolved organic matter (fDOM), pH, specific conductance, turbidity, water temperature, and water surface height.

This is a catalogue of the earthquake data recorded during the 2023 Kīlauea Seismic Imaging Experiment by a consortium of government and academic scientists under the auspices and with the coordination of the U.S. Geological Survey (USGS) and the National Park Service at Hawai'i Volcanoes National Park. Steve Roecker (Rensselaer Polytechnic Institute) produced this catalogue and then...

This data release provides information on lake trout (Salvelinus namaycush) collected from 10 lakes located in Alaska's national parks. The data are in two tables: (1) capture information, (2) morphometric measurements and mercury (Hg) concentrations, and a folder of individual photographs of captured lake trout. Lake trout were collected between September of 2020 and August of 2023 from...
