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.

This dataset contains nutrient, chlorophyll, oxygen, and others taken by CTD water samples from the USCGC Healy, cruise HE1702, in the Bering and Chukchi Seas, and the Arctic Ocean. Discrete water samples from 141 CTD casts were collected in the Chukchi Sea from US Coast Guard Cutter Healy (HE1702, August 26 to September 15, 2017) as part of the 2017 Distributed Biological Observatory – Northern Chukchi Integrated Study (DBO-NCIS). The goal of DBO-NCIS was to document and understand ongoing changes to the Pacific-Arctic ecosystem in light of the changing physical drivers. Sampling and transects on this research cruise were along standard DBO lines in areas 1, 3, 4 and 5. Nutrients and chlorophyll samples were collected at all process stations in support of benthic studies and net tows. A total of 410 nutrient samples were collected, filtered, and stored frozen at -80 degrees C. They were processed post-cruise at the Pacific Marine Environmental Laboratory (PMEL) for determination of nitrate, nitrite, ammonium, silicate and phosphate concentrations. Total chlorophyll was collected at 71 stations at standard depths of surface, 10 m, 20 m, 30 m, 40 m, and 50 m or bottom depth when stations were shallower than any standard depth. Samples were filtered through GF/F glass fiber filters under low vacuum, and the filters were stored frozen at -80 degrees C. Samples were analyzed at NOAA/PMEL. For calibration of the CTD oxygen probe, 48 samples were samples collected for dissolved oxygen. See data type descriptions for more processing details. Data have been submitted in csv format with a 1-line header defining columns. Related profile data from CTD instruments were processed and are available at WHOI.

This CTD and bottle profile data set, consisting of 28 casts, was collected in the Bering Sea from NOAA Ship Oscar Dyson (DY1104, 3DY11), 2011-09-22 to 2011-09-27. The cruise was under the NOAA, North Pacific Climate Regimes and Ecosystem Productivity (NPCREP) program. Two temperature (T_28 & T_35), 2 salinity (S_41 & S_42) and 2 oxygen (O_65 & CTDOXY_4221) variables were collected and Sigma-T (ST_70) calculated. Two PAR variables are listed in uEin m-2 s-1 and voltages. Raw fluorometer (rFv_971) are in volts and WetStar fluorometer are in micrograms/Liter. Nutrient data are discrete niskin-bottle samples in units of microMol/Liter: Phosphate, Silicate, Nitrate, Nitrite, Ammonium (respectively labeled PO4, SiO4, NO3, NO2, NH4). Profiles were processed at NOAA/PMEL EcoFOCI program using SeaBird software and standard techniques. Profile data are averaged to a 1-meter grid, with missing data listed as 1.0E-12 (CTD) and NaN (Nutrients). CTD data contact: Phyllis Stabeno, Peggy Sullivan, Shaun Bell. Data are in CSV. Longitude is in deg_WEST.

This is an archive of CTD data from the 2024 Bering Strait mooring cruise. The cruise was funded by the NSF-Arctic Observing Network grants: - PLR-2153942 (PIs: Woodgate and Peralta-Ferriz). The data are from a ~ 11 day cruise - on the US vessel Norseman II - from 8th-18th July 2024 - sailing from and to Nome, Alaska, USA - to the Bering Strait and southern Chukchi Sea The cruise was also to service oceanographic moorings in the strait and those data are archived separately. This is an archive of both hydrographic and bottle data. A total of 154 casts were taken and are included in this archive. Water samples were taken for salinity (6) and nutrients (195) from the CTD rosette. Nutrient data are included in this archive. Salinity samples were only to confirm sensor/bottle discrepancies and are not included in this archive. A separate pumping system was used to take trace metal (and accompanying nutrient) samples during this cruise (lead: Laramie Jensen). These data are archived separately. Stations were taken in US waters near mooring locations and on sections in the Bering Strait and southern Chukchi Sea. See cruise report, accompanying event log and data headers for map, station locations, calibration, and processing details. The data are taken using an SBE9-11plus system, recording - pressure - temperature (dual system) - conductivity (dual system) - oxygen (dual system) - fluorescence - turbidity connected also to an - SUNA nitrate sensor, recording both internally and with the CTD data. Bottle samples returned to the University of Washington (UW) for analysis post cruise.

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. Data are in NetCDF, longitudes are in "degree_west".
