This CTD and Niskin bottle data set, consisting of 17 casts, was collected in the Chukchi and Bering Seas from the F/V Aquila (cruise AQ15-01, September 8 - 28, 2015). The cruise was funded by DOI Bureau of Ocean Energy Management (BOEM) through the NOAA National Marine Mammal Laboratory. 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 (channel 1) temperature and salinity. Nutrient samples were analyzed according to the methods of Gordon et al, 1993 and Mantoura, Woodward, 1983 (see references in metadata). Samples were collected in 50 ml high-density polyethylene bottles that were rinsed first with 10% HCl ...
