    This dataset contains geochemical data of ground ice and pore water in frozen sediments from the Barrow Permafrost Tunnel in Utqiaġvik, Alaska. Data were collected in May 2017 and May 2018. For a complete list of measurements, refer to the full dataset description in the supplemental file 'Dataset_description.pdf'.

  • Dataset
    Temperature, salinity, water isotope, and inorganic nutrient profiles of sea ice core sections collected offshore near Utqiaġvik, Alaska, USA in May 2017 and 2018.

    Sea ice cores were collected at 71.2944˚N, 156.7153˚W and 71.3729˚N, 156.5073˚W in May 2017 and at 71.4730˚N, 156.7294˚W in May 2018. Sea ice cores were drilled with a MARK II ice auger (Kovacs Enterprise). The cores were sectioned immediately after collection with a clean rust-proof, custom alloy bow saw in the field in 5 cm sections and each was collected in sterile Whirlpak® bags. Core sections were melted at room temperature before volumes were allocated for nutrient, water isotope, and bulk salinity measurements. Analytical measurements were made upon sample return to the University of Washington and to the University of Alaska Fairbanks. Associated temperature profile data were acquired from the nearby UAF Sea Ice Mass Balance site.

  • Dataset
    Brine samples from both sea ice and cryopeg near Utqiaġvik, Alaska, USA from 2017-05-08 to 2018-05-10
    (Biological and Chemical Oceanography Data Management Office (BCO-DMO). Contact: bco-dmo-data@whoi.edu, 2020-07-16) Deming, Jody W. ; Eicken, Hajo ; Iwahana, Go
    Brine samples were collected from both sea ice and cryopeg near Utqiaġvik, Alaska, USA. Snow and ice thickness along with sackhole core depth information are available for sea ice samples. Bacterial and viral abundances along with temperature, pH, salinity, inorganic nutrients, organic nutrients, EPS, and water isotopes were measured for select samples. For a complete list of measurements, refer to the full dataset description in the supplemental file 'Dataset_description.pdf'.
