CTD profile data (91 casts) were collected in the northern Bering, Chukchi, Beaufort Seas, and Arctic Ocean from the Research Vessel Ocean Starr (OS1901 Legs 1,2,3), August 6 to September 27, 2019. The research cruise was part of the Arctic Integrated Ecosystem Survey (Arctic IES) funded as part of the North Pacific Research Board (NPRB) Arctic Integrated Ecosystem Research Program (Arctic IERP). The program and research on this expedition were sponsored by NPRB and the Bureau of Ocean and Energy Management (BOEM), with in-kind support by the National Oceanic and Atmospheric Administration (NOAA, PMEL and AFSC). These data contribute to understanding how reductions in Arctic sea ice and associated changes in the physical environment influence the flow of energy through the ecosystems of the Chukchi and Beaufort Seas. The physical data are part of a wider range of data collected towards this effort. This year’s survey was notable in that there was no sea ice within the survey region from 72.5N in the Chukchi Sea into the nearshore regions of the Beaufort Sea and south to the Bering Strait. Ice was present in the northern regions of our survey area during surveys that occurred in 2012 and 2013. Additionally, sea surface temperatures were warmer than previous years ranging from 5.3°C (42°F) to 10.9°C (52°F); the coldest sea surface temperatures were found at the offshore Chukchi Slope stations, with the warmest found inshore between Icy Cape and Ledyard Bay. CTD data and water samples were collected by NOAA, PMEL Ecosystems & Fisheries-Oceanography Coordinated Investigations (EcoFOCI). Variables include dual temperatures (°C), dual salinity, chlorophyll fluorescence(ugrams/l), Photosynthetic Active Radiation (PAR, uEin m-2 s-1), oxygen concentration (umol/kg), and calculated values Sigma-T (kg m-3) and oxygen percent saturation (percent) This dataset contains 1-meter-averaged water-column profile data.

M4. Biophysical moorings deployed 2014-2018 at established NOAA/PMEL data-collection site "M4" on the eastern Bering Sea Shelf resulted in five annual time-series data sets that are presented herein. Moorings were deployed at the M4 site in the Fall of each year at approximate location 57.89N, 186.9W, NE of the Pribilof Islands, Alaska and SW of Nunivak Island, Alaska; in September 2015, 2016 and 2017, and October in 2014 and 2018. Contract Fishing Vessel Aquila was used for deployments in 2014, 2015, 2016 and 2018 (cruises AQ1401, AQ1501, AQ1601 and AQ1801, respectively). NOAA Ship Oscar Dyson was used for deployment in 2017 (cruise DY1708). Moorings and instruments were left over winter and recovered the following Fall with the exception of the 2018 data set which was left in the water in 2019 due to prohibitive weather conditions and was recovered in 2020. Biophysical subsurface mooring filenames, e.g. 15bs-4a, indicate deployment year (15 for 2015) area (bs is Bering Sea) and defined location ("4" for M4). Instrumentation included SeaBird SBE-37 (Microcat), SBE-39, SBE 56 (temperature sensor) and SBE 16 (Seacat) profilers, and WetLabs EcoFluorometers; instruments and deployed depths varied between years. 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 between 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 the 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.

The USF, College of Marine Science, Ocean Circulation Group under the direction of Dr. R.H. Weisberg is maintaining an array of moored instruments on the west Florida shelf for in-situ measurements of currents, temperature, salinity, surface meteorology, and sea level. Our field work also includes participation in monthly hydrographic cruises. In addition to the field work we are running numerical ocean circulation model experiments on the west Florida shelf in collaboration with the biological modeling group headed by Dr. J. Walsh.
