Data

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...

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 data release contains observational data from a breeding bird inventory using standardized point counts conducted during May-June 2005 in Kenai Fjords National Park (KEFJ), Alaska. It also includes a single survey conducted for owls on the night of 30 April 2005. Data tables include 1) survey route details, 2) survey point details, 3) survey habitat details at survey points, 4) bird...

This data release includes 4 child items with data regarding metabolic rate, body composition, diet, behavior, blood chemistry, stable isotope, tri-axial accelerometer, and GPS locations of grizzly bears (Ursus arctos) on the North Slope of Alaska, 2023. Child Item 1: "GPS Location Data from Grizzly Bears (Ursus arctos) Instrumented on the North Slope of Alaska, USA, 2023" Child Item 2:...

This data release includes 3 child items with tracking data for caribou, a terrestrial mammal that ranges between the Alaska and Canada. Child Item 1: "GPS Tracking Data for Caribou (Rangifer tarandus granti) from the Denali Herd, Alaska, 2010-2018" Child Item 2: "GPS Tracking Data for Caribou (Rangifer tarandus granti) from the Fortymile Herd, Alaska, 1998-1999" Child Item 3: "GPS...

Waterfowl were observed staging at Nanvak Bay, Togiak National Wildlife Refuge in southwest Alaska between 31 August and 27 September 1992. This data release contains five tables including 1) aerial surveys, 2) band resights for Black Brant (Branta bernicla nigricans), 3) Black Brant age ratios, 4) bird migration observations, and 5) taxonomy table for observed birds.

This dataset contains known and estimated ages of polar bears sampled from the southern Beaufort Sea of Alaska. Whole blood was collected from polar bears of known chronological age between 1987 and 2016. Chronological age was known because all the bears in this data set were initially captured as a dependent cub-of-the-year, yearling, or 2-year-old, and that allowed us to know...

This dataset includes details of 2,745 tracking devices (hereafter "trackers") deployed on shorebirds, including traits of the tags, traits of the shorebirds, and locations of the field sites. The dataset was used in the accompanying paper to evaluate how factors affected "success" of each tag package (tracker + attachment to the bird), where "success" was defined as whether the tag...

This data release provides a vector geospatial shapefile of river and creek segments within Dolly Varden (Salvelinus malma) habitat in the Noatak River drainage (DeCicco 1985) classified for metal impairment between 1986 and 2024. The impairment classifications were based on visual inspection of Landsat and Sentinel satellite imagery. Also provided are the satellite images (as raster...

This dataset provides information on aquatic invertebrate composition from ponds (n = 16; surface area 0.02 km2) and lakes (n =16, surface area > 0.10 km2) on the central Arctic Coastal Plain of Alaska. Ponds and lakes were selected for sampling as part of a larger study of Arctic water body food webs. Details on the study area and findings are published in Laske et al. 2018 and Laske et...
