This data set documents the carbon and nitrogen stable isotope ratios of age-0 Arctic cisco (Coregonus autumnalis) captured in Prudhoe Bay, Alaska in August 2009.

This dataset contains isotope results of stable isotope (δ13C and δ15N) and radicoarbon (F14C) analyses of muscle tissue from fish collected in the nearshore Beaufort Sea, Alaska in summers 2017-2019.

These data are in a single table that provides date and location information of Tundra Swans (Cygnus columbianus) that were sampled in Alaska for feathers that were subsequently used in a stable isotope analysis. Results of deuterium, nitrogen, and carbon stable isotope analysis of feathers are provided.

This dataset contains benthic and pelagic invertebrate stable carbon and nitrogen isotope data collected in the Chukchi Sea, U.S. Arctic during the 7 August 2017 - 22 August 2017 Arctic Marine Biodiversity Observing Network (AMBON) research cruise aboard the vessel Norseman II. The dataset contains a comma separated values (csv) files exported from Microsoft Excel. These data were generated from samples collected with trawls, grabs, and plankton nets during the research cruise. The data in the file named AMBON2017_Stable Isotopes_Database_final.csv describe the carbon and nitrogen stable isotope values of invertebrate samples with and without various chemical treatments to eliminate carbonates and lipids. Full location and taxonomic information is given for each sample.

This dataset is one table with information on the carbon isotopes in samples collected from organic and mineral soils, streams, algae, invertebrates, and fish in the Arctic Network Parks.

This dataset includes information on the carbon samples that were collected from organic and mineral soils, streams, algae, invertebrates, and fish in the Arctic Network Parks.

This dataset includes carbon and nitrogen isotope concentrations measured in polar bear hair and marine mammal prey muscle and blubber samples collected 1978-2019 in the Beaufort and Chukchi Seas. Marine mammal prey samples were collected opportunistically either from polar bear seal kill sites or from marine mammals harvested by Native hunters, including ringed seal, bearded seal, gray whale, Pacific walrus, bowhead whale, beluga whale, spotted seal and ribbon seal. All prey samples were collected within the Alaska Beaufort or Chukchi Sea with the exception of gray whale samples that were collected in Chukotka. More specific information on the location in which prey samples were collected are provided within the data. Hair was collected from polar bears captured on the sea ice or land in the spring or fall from 1987-1989 and 2008-2017 in the Russia and/or Alaska portions of the Chukchi Sea and 1983-1989 and 2004-2016 in the Alaska Beaufort Sea. Whole hairs were analyzed for carbon and nitrogen isotopes. Prey samples were analyzed separately as blubber lipids, lipid-extracted blubber protein, bulk muscle, and lipid-extracted muscle. Not all tissues were available for all individual prey samples.
