    • Water temperature, conductivity, and others taken by CTD and Niskin bottles from the research vessel Norseman II Data for Arctic Marine Biodiversity Observing Network, AMBON, Program in the Chukchi Sea from 2017-08-07 to 2017-08-22 (NCEI Accession 0229072)

    Metadata Updated: February 1, 2025

    This dataset contains temperature and salinity data collected in the Chukchi Sea during the 7 August - 22 August 2017 Arctic Marine Biodiversity Observing Network (AMBON) research cruise. The dataset consists of bottle samples and CTD data.

    The data provides information on important Arctic Chukchi Sea ecosystem parameters, including temperature, salinity, pressure, and fluorescence as an index of phytoplankton biomass. In aggregate these variables are basic descriptors of the water masses entering the Chukchi Sea from the Pacific through the Bering Strait.

    The dataset consists of three files.

    • AMBON2017_CTDprofiles.ascii (also in csv and netcdf)
    • AMBON2017.hdr
    • AMBON2017_ctdBottleData_L2_v1.csv

    The first file is a ASCII file consisting of Seabird SBE55 CTD measurements from the depths at which the Niskin bottles were tripped; the file is intended to complement the file named 'AMBON 2017 bottle file new- Nutrients_chlorophyll bottle file.csv' in the Arctic Marine Biodiversity Observing Network (AMBON): Water column and benthic processes project (Cooper and Grebmeier).

    The second file is a ASCII file consisting of Seabird SBE55 Conductivity, Temperature, Depth (CTD) header information (named AMBON2017.hdr); the file accompanies the main CTD data file. The dataset describes each CTD cast number, location, bottom depth and other ancillary information.

    The third file is a ASCII file consisting of Seabird SBE55 Conductivity, Temperature, Depth (CTD) downcast data (AMBON2017_ctdBottleData_L2_v1.csv). Data were post calibrated and adjusted to bottled samples.

    Data are in ASCII, CSV, and NetCDF.
