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.

Purpose The 2016 Arctic Long-Term Integrated Mooring Array (ALTIMA) cruise, Nome to Dutch Harbor, Alaska, took place on board the F/V Aquila, September 4 - 29, 2016. This 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). Data collection added to long-term datasets initiated under several BOEM-funded studies: North Pacific Right Whale (PRIEST), Bowhead Feeding Ecology Study (BOWFEST), Chukchi Acoustics, Oceanography, and Zooplankton study (CHAOZ), the CHAOZ-Extension study (CHAOZ-X), and ARCWEST. The ALTIMA cruise was a multi-disciplinary effort to monitor marine mammals and seabirds and the ecosystem of the Chukchi Sea in order to understand the mechanisms responsible for high biological activity in the region, in order to predict, in a qualitative way, the effects of climate change on these preferred habitats.

Processing Steps
  • Parameter or Variable: WATER TEMPERATURE - channel 1 (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. Each cast was visually reviewed for reasonableness, density inversions (greater than 0.02 sigma-t) caused by spurious measurements, and comparison of dual temperature and conductivity sensor data.
