Biophysical measurements (temperature, salinity, oxygen, chlorophyll a), and ocean currents (U, V) collected from NOAA moorings at long-term observatory site M8 in the Southeastern Bering Sea, Alaska, by the EcoFOCI group at NOAA, PMEL, 2015-09-24 to 2019-09-23 (NCEI Accession 0302602)

These time-series data sets are from instruments on biophysical and ADCP (current meter) moorings at NOAA/PMEL Data Observatory "M8" on the southeastern Bering Sea Shelf. These two mooring types, were deployed at the "M8" site in the Fall of each year; in September in 2015, 2016 and 2017, and October in 2018. Contract Fishing Vessel Aquila was used for deployments in 2015, 2016 and 2018 (cruises AQ1501, AQ1601 and AQ1801, respectively). NOAA Ship Oscar Dyson was used for deployments in 2018 (cruise DY1808). Moorings and instruments were left over winter and recovered the following Fall. Biophysical subsurface mooring filenames, e.g. 15bs-8a, are indicated by "bs"; "bsp" indicates a separate ADCP/WCP current-meter mooring. Instrumentation included Teledyne RDI Workhorse Sentinel ADCP (WCP), SeaBird SBE-37 (Microcat), SBE-39, SBE 16 (Seacat) profilers and WetLabs EcoFluorometers. Data include current components U and V, temperature, conductivity, salinity, pressure, water depth, oxygen concentration, calculated oxygen percent saturation, raw chlorophyll fluorescence and chlorophyll a.

The cruise was funded by NOAA, Pacific Marine Environmental Laboratory EcoFOCI program and NOAA Arctic Research Program with additional support from AOOS, the NOAA-regional ocean data partnership.

Deployment and recovery operations on this cruise were managed by EcoFOCI personnel from NOAA/PMEL. Mooring time series data were processed at NOAA/PMEL/EcoFOCI using standard techniques. Time is recorded as UTC. Data contacts: Phyllis Stabeno, Shaun Bell, Ryan McCabe, Peggy Sullivan.
