    • Vessel line-transect surveys of Arctic marine mammals in the Chuckchi Sea, Arctic Marine Biodiversity Observing Network (AMBON) research cruise on the vessel Norseman II, 2015-08-09 - 2015-09-03 (NCEI Accession 0177802)

    Metadata Updated: December 1, 2023

    This dataset contains marine mammal observation data conducted during shipboard transects in the Chukchi Sea during the 9 August - 3 September 2015 Arctic Marine Biodiversity Observing Network (AMBON) research cruise. The dataset is three comma-separated values (csv) files exported from the marine bird and mammal observation software WinCruz from the entire survey. Two data files contain the dates, times, latitude, longitude, species and best-high-low estimates of numbers for each cetacean (whales) and pinniped (seals, seal lions, and walrus) sightings. A third data file contains the track of the ship (as geographic coordinates) and the Beaufort sea state at two minute intervals as a measurement of effort. This dataset was transformed from the native format into a table structure using Darwin Core Archive (DwC-A, occurrence core) term names as column names.
