CTD profile data (109 casts) were collected in the northeast Bering Sea and Chukchi Sea from the Fishing Vessel Bristol Explorer (cruise BE1201) during a pelagic fish survey (Arctic EIS), August 6 to September 27, 2019. CTD casts occurred along a previously-defined trawl survey station grid with stations ~30nm apart. Northern Bering Sea stations were between 60°N and Bering Strait; Chukchi stations sat between the Bering Strait and 72.5°N. Profile data and water samples were collected by NOAA, AFSC as a part of the Ecosystems & Fisheries-Oceanography Coordinated Investigations (EcoFOCI) program in collaboration with Pacific Marine Environmental Laboratory (PMEL). Profile variables include dual temperatures (°C), dual salinity, chlorophyll fluorescence(ugrams/l), oxygen concentration (umol/kg), transmission (percent), and calculated values Sigma-T (kg m-3) and oxygen percent saturation (percent). This data set contains 1-meter-averaged water-column profile data. Profile data from CTD instruments were processed at NOAA/PMEL/EcoFOCI using standard techniques. Null values are represented as 1.00E+35. CTD data contacts: Phyllis Stabeno, Calvin Mordy, Peggy Sullivan, Shaun Bell. Scientists from National Oceanic and Atmospheric Administration (NOAA), Alaska Fisheries Science Center (AFSC); Auke Bay Laboratories Ecosystem Monitoring and Assessment (EMA); Arctic Ecosystem Integrated Survey (Arctic Eis); Pacific Marine Environmental Laboratory (PMEL) ; Ecosystems and Fisheries-Oceanography Coordinated Investigations (EcoFOCI); University of Washington, Cooperative Institute for Climate, Ocean and Ecosystem Studies participated in the cruise.

The Ecosystems and Oceanography Division of the Pacific Islands Fisheries Science Center, National Marine Fisheries Service, National Oceanic and Atmospheric Administration (NOAA), conducted a cruise, OES 04-03, in March 2004 near American Samoa on the R/V Oscar Elton Sette. Meridional transects were made along 170.5W and 169W between 10S and 17S. This finalized data set contains the profiles of temperature, salinity, dissolved oxygen, and chloropigments. The former three go to 1000 dbars and the latter variable to 200 dbars.

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.

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.

CTD profile data (128 casts) were collected in the Chukchi and Beaufort Seas from the Fishing Vessel Ocean Starr (OS1701 Legs 1,2,3), August 1 to October 4, 2017). The 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). 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 two Seas. The physical data are part of a wider range of data collected towards this effort. Notably, there was no sea ice present in the northern regions during the survey area as compared to surveys that occurred during 2012 and 2013 (see cruise report).
