This CTD data set, consisting of 70 casts, was collected in the Chukchi Sea ice cruise AQ12-01 from the fishing vessel Aquila (August 12 - September 6, 2012). 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, ammonium, and chlorophyll. Discrete chlorophyll (bottle sample) data are submitted separately through NOAA/AFSC, Jeffrey M. Napp. Data files are on a 1-meter grid and combine both averaged CTD profile data, and nutrient bottle samples where missing data are listed as 1e+35. CTD data contact: Phyllis Stabeno, Peggy Sullivan. Nutrient bottle data contact: Calvin Mordy. Data are in CSV format.

Processing Steps
  • Parameter or Variable: WATER TEMPERATURE (measured); Units: degrees C; Observation Category: in situ; Sampling Instrument: SeaBird SBE-911plus CTD; Sampling and Analyzing Method: At each CTD location, the rosette was lowered to 10 meters to equilibrate, brought to surface, then deployed to a close-to-bottom depth, at a rate of ~30m/minute, and ~50m/minute below ~150 meters depth. Profiles were collected on the downcast using dual SeaBird temperature sensors calibrated to ITS-90 temperature.; Data Quality Method: Data were processed and calibrations applied using SeaBird Seasoft software and pre- and post-cruise calibration data. Post-processing at PMEL included filtering extreme outliers and extrapolation of top 3-10 meters to the surface.
