Data

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...

This dataset provides origin (hatchery vs. wild) and energy density (kJ g-1) of juvenile pink (Oncorhynchus gorbuscha) and chum salmon (O. keta) from the eastern Gulf of Alaska, 2010–2024. Juvenile salmon were sampled from rhinoceros auklet (Cerorhinca monocerata) diets on Middleton Island (59.4375 N, 146.3277 W) located near the continental shelf break in the Gulf of Alaska. Auklets...

Glacial and proglacial landscapes provide critical sources of water and solutes to downstream riverine and marine ecosystems. This dataset contains samples from the dominant landscape types in the Nellie Juan River basin, collected from surface streams, groundwater, rain, and snow. Water samples were also collected from streams near the Exit, Gulkana, and Kennicott Glaciers. Snow samples...

The dataset lists specific activities of Cesium-137 in disintegrations per minute per gram (dpm per g) from 21 samples in the upper 33 centimeters of sediment core 22KAR-21A collected in Karluk Lake, Kodiak Island, Alaska.

The data set contains geochemical data for 1,524,014 rock, sediment, soil, and mineral samples collected by the U.S. Geological Survey within US state, territory or Economic Exclusive Zone (EEZ) boundaries, and analyzed from 1962 through 2023 either in the analytical laboratories of the Geologic Discipline of the USGS or by contract with commercial analytical laboratories. These data...

This dataset is one table with data collected and derived from female polar bears sampled in Alaska's southern Beaufort Sea during 1982-1985. Collected data includes demographic information. Derived data includes blood-based analyte values determined from serum samples. Serum samples were analyzed in 1986 by Evergreen Professional Services (Bothell, WA, USA). It is believed that a...

These data contain carbon and nitrogen isotope ratios in samples of Black Oystercatcher tissues (feathers and claws), as well as tissues from several species of prey, including mussels, limpets, clams, and snails. Samples were collected across a significant portion of the Black Oystercatcher's range, including the coast of the northern Gulf of Alaska down to the Salish Sea in British...

This dataset consists of sample descriptions and radiocarbon age data from Karluk Lake on Kodiak Island, Alaska; samples were analyzed at Northern Arizona University, Arizona Climate and Ecosystems Isotope Laboratory https://in.nau.edu/aceisotopelab/.

This dataset consists of sample descriptions and radiocarbon age data from Esther Lake on Esther Island in Prince William Sound, Alaska; samples were analyzed at Northern Arizona University, Arizona Climate and Ecosystems Isotope Laboratory https://in.nau.edu/aceisotopelab/.
