Biophysical ocean measurements (temperature, salinity, chlorophyll a) collected at long-term Mooring site M5 on the eastern Bering Sea shelf, Alaska, by the EcoFOCI group at NOAA, PMEL, 2015-09-25 to 2019-09-22 (NCEI Accession 0304094)

Four time-series data sets are from instruments on biophysical moorings at the established NOAA/PMEL data-collection site "M5" on the eastern Bering Sea Shelf. Mooring were deployed at the M5 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 2017 (cruise DY1708). Moorings and instruments were left over winter and recovered the following Fall. Biophysical subsurface mooring filenames, e.g. 15bs-5a, indicate year (15) area (bs) and defined location ("5" for M5). Instrumentation included SeaBird SBE-37 (Microcat), SBE-39, SBE 56 (temperature sensor) profilers and WetLabs EcoFluorometers. Data include temperature, conductivity, salinity, pressure, water depth, 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. The Ecosystem and Fisheries-Oceanography Coordinated Investigations (EcoFOCI) program is a partnership with NOAA PMEL and NOAA Alaska Fisheries Science center (AFSC). Scientists from PMEL and the University of Washington cooperative institute (CICOES) collaborated in this data collection and related data processing and analysis. Deployment and recovery operations on this cruise were managed by EcoFOCI personnel from NOAA/PMEL, NOAA/AFSC and UW/CICOES. 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. Data are in NetCDF. Longitudes are in degW.
