    • Water column chlorophyll, nutrients, temperature, salinity, and others taken by CTD and Niskin bottles from the research vessel Norseman II in the Chukchi Sea for the Arctic Marine Biodiversity Observing Network program from 2015-08-12 to 2017-08-22 (NCEI Accession 0216386)

    Metadata Updated: November 1, 2023

    This dataset contains water temperature, salinity, and others taken by CTD, as well as water column chlorophyll, nutrients, and others from Niskin bottle samples collected in the Chukchi Sea during the 2015-08-12 to 2015-09-03 and the 2017-08-06 to 2017-08-22 Arctic Marine Biodiversity Observing Network (AMBON) research cruises aboard the research vessel Norseman II. This dataset consists of two comma-separated values (csv) files (naming convention 'AMBON [YYYY] bottle file new_NutrientChlaDelO18.csv) containing measurements of water samples collected by a Niskin bottle array on a Seabird SBE55 CTD at hydrographic stations in each 2015 and 2017. These data files contain chemistry measurements made on bottle samples, including Chlorophyll a Concentration (micro-g/L), and nutrient concentrations [micro-mol/L] (Ammonia, Phosphate, Nitrite+Nitrate, and Silicate). Water samples were also collected for analysis of 18O/16O ratios. The data files also include physical information, depth, salinity and temperature measurements from the CTD at the location of bottle sample collection. Two source CTD ASCII data files (named AMBON[YYYY]_bottles.all) consisting of measurements from the depths at which the Niskin bottles were tripped are also included in this dataset. The data provides information on important Arctic Chukchi Sea ecosystem parameters, including temperature, salinity, pressure, and fluorescence as an index of phytoplankton biomass. Data are in text and CSV formats.
