        abstract:  CTD profiles and Niskin bottle samples were collected on the northeast Bering Sea shelf September 20 to September 30, 2019 from the NOAA vessel Oscar Dyson (DY1908). This data set contains 1-meter-averaged water-column profile data and discrete bottle-sample data from CTD Niskin bottles. Profile data include temperature, salinity, chlorophyll fluorescence, PAR, oxygen and turbidity. Bottle-sample data include chlorophyll, and nutrients (nitrate, nitrite, phosphorus, silicate, and ammonium). CTD cast locations include a subset of the established 70-meter isobath line stations between PMEL/EcoFOCI moorings M2 (56.87 N,164.05 W) and M8 (62.20 N,174.67 W), and across Unimak Pass at Unimak Island in the Aleutian Islands, and casts at other mooring stations (see Data at NOAA, EcoFOCI web site). Chlorophyll data were processed by NOAA, Alaska Fisheries Science Center (AFSC) using standard techniques. Profiles were processed at NOAA/PMEL EcoFOCI program using SeaBird software and standard techniques; nutrient data were also processed at NOAA,PMEL (C.W.Mordy). Data contacts: Phyllis Stabeno, Calvin Mordy, Colleen Harpold, Shaun Bell, Peggy Sullivan. Related raw profile data and underway ship data are available from NOAA/NCEI (Accession 0206459) per NOAA ship R2R program contribution. Scientists from the National Oceanic and Atmospheric Administration (NOAA), Pacific Marine Environmental Laboratory (PMEL); Alaska Fisheries Science Center (AFSC); Ecosystems and Fisheries-Oceanography Coordinated Investigations (EcoFOCI); University of Washington, Cooperative Institute for Climate, Ocean and Ecosystem Studies (CICOES) participated. Data are in NetCDF. Chlorophyll data are in XLSX format.
        purpose:  Bering Sea research and data collection are part of EocFOCI, a NOAA cross-line effort between the Pacific Marine Environmental Laboratory (PMEL) and the Alaska Fisheries Science Center (AFSC), focused on improving fisheries stock assessments and continued exploration of the Bering Sea ecosystem through the collection of fisheries acoustics, zooplankton, and physical oceanographic data. This 2019 cruise was part of an annual Fall Cruise to maintain NOAA observing systems moorings.

                description:  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. 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. Profile data were bin-averaged to 1 meter..
