    • Water temperature, salinity, nutrient samples, and other data taken by CTD and Niskin bottles from the fishing vessel Aquila, cruise AQ16-01, in the Bering, Chukchi, and Beaufort Seas from 2016-09-04 to 2016-09-29 (NCEI Accession 0281203)

    Metadata Updated: December 1, 2023

    This CTD and Niskin bottles data set, consisting of 71 casts, was collected in the Chukchi Sea from the F/V Aquila (AQ16-01, September 4 - 29, 2016) within the Arctic Long-Term Integrated Mooring Array (ALTIMA) area. The cruise was funded by NOAA’s Office of Oceanic and Atmospheric Research (OAR), with supplemental funding from the Bureau of Ocean Energy Management (BOEM) through the Arctic Whale Ecology Study (ARCWEST). These data add to long-term datasets begun under several BOEM initiatives (see “Purpose”). CTD operations on this cruise were managed by EcoFOCI personnel from NOAA/PMEL. Profile data from CTD instruments were processed at NOAA/PMEL/EcoFOCI using standard techniques. Data from bottle samples include phosphate, silicate, nitrate, nitrite and ammonium. Profile data are averaged to a 1-meter grid, with missing data listed as NaN. Salinity was calculated (PSS-78), from conductivity and temperature (ITS90). Sigma-t was calculated from primary temperature and salinity.

    Nutrient samples were analyzed according to the methods of Gordon et al, 1993 and Mantoura, Woodward, 1983 (see references below). Samples were collected in 50 ml high-density polyethylene bottles that were rinsed first with 10% HCl prior to each station, and rinsed at least three times with sample before filling. Some samples were refrigerated for 3-12 hours prior to analysis, and some frozen for later analysis.

    CTD data contact: Phyllis Stabeno, Peggy Sullivan, Shaun Bell, Calvin Mordy (nutrients). This cruise was conducted by NOAA/OAR, NMML, AFSC, BOEM, PMEL and EcoFOCI participants. Data are in CSV format. Longitudes are in deg_west.
