Conductivity, temperature and depth (CTD), primary production, and underway data were collected as part of Processes and Resources of the Bering Sea Shelf (PROBES) Project. Ship THOMAS G. THOMPSON was used to collect data from Bering Sea. The data was collected over a period spanning from April 10, 1978 to August 15, 1980 by Pacific Marine Environmental Laboratory (PMEL), Seattle, WA. Three tapes containing data files L01200 = TAPE FILES 1 - 5; L01201 = TAPE FILE 6; and A01361 W13748 were submitted. Temperature, chlorophyll-a, PO4-P, NO3-N, NO2-N, and SIO3-SI were measured for primary production. These data files are in NODC standard High-Resolution CTD/STD (F022) format, NODC standard F029 Primary Productivity format, and University of Alaska 099 Underway data format. The F022 format contains high-resolution data collected using CTD (conductivity-temperature-depth) and STD (salinity-temperature-depth) instruments. As they are lowered and raised in the oceans, these electronic devices provide nearly continuous profiles of temperature, salinity, and other parameters. Data values may be subject to averaging or filtering or obtained by interpolation and may be reported at depth intervals as fine as 1m. Cruise and instrument information, position, date, time and sampling interval are reported for each station. Environmental data at the time of the cast (meteorological and sea surface conditions) may also be reported. The data record comprises values of temperature, salinity or conductivity, density (computed sigma-t), and possibly dissolved oxygen or transmissivity at specified depth or pressure levels. Data may be reported at either equally or unequally spaced depth or pressure intervals. A text record is available for comments. The Primary Productivity (F029) file contains data from measurements of primary productivity. The data are collected to provide information on nutrient levels and nutrient flow in offshore areas. In addition to cruise information, position, date, time, sampling depths, bottom depth, and environmental information, this file may contain measured parameters including: concentrations of nutrients such as phosphate, nitrate, silicate, and ammonia; temperature and salinity; and carbon assimilation. Measurements of chlorophyll a, phaeopigment, and carbon assimilation may be reported as integrated values. A free-text record is available for comments.

This dataset includes currents data from current meters in the Bering Sea, collected by Dr. H.J. Niebauer of the Institute of Marine Science. The meters were deployed and recovered during R/V Alpha Helix cruise HX112. This dataset also includes CTD data collected aboard the R/V Thompson on cruise number TT213 in the Bering Sea and Chukchi Sea area between 21-Jul-1987 to 10-Aug-1987 by L. Coachman of the University of Washington, Dept. of Oceanography, CTD data collected aboard the R/V Thompson on cruise number TT214 in the Bering Sea and Chukchi Sea area between 17-Aug-1987 and 29-Jul-1987 by C.P. McRoy of the Institute of Marine Science, CTD data collected aboard the R/V Alpha Helix in the Gulf of Alaska on cruise number HX108 between 30-Nov-1987 and 13-Dec-1987 and cruise number HX114 between 16-Jun-1988 and 29-Jun-1988 by Dr. T.C. Royer of the Institute of Marine Science. Data has been processed by NODC to the NODC standard F015- Current Meter Data and F022- CTD High Resolutions formats. The F015 format is used for time series measurements of ocean currents. These data are obtained from current meter moorings and represent Eulerian method of current measurement, i.e., the meters are deployed at a fixed point and measure flow past a sensor. Position, bottom depth, sensor depth, and meter characteristics are reported for each station. The data record comprises values of east-west (u) and north-south (v) current vector components at specified date and time. Current direction is defined as the direction toward which the water is flowing with positive directions east and north and negative directions west and south. Data values may be subject to averaging or filtering and are typically reported at 10-15 minute time intervals. Water temperature, pressure, and conductivity or salinity may also be reported. A text record is available for optional comments. The F022 format contains high-resolution data collected using CTD (conductivity-temperature-depth) and STD (salinity-temperature-depth) instruments. As they are lowered and raised in the oceans, these electronic devices provide nearly continuous profiles of temperature, salinity, and other parameters. Data values may be subject to averaging or filtering or obtained by interpolation and may be reported at depth intervals as fine as 1m.

This dataset contains ocean temperature and salinity profiles from CTD and bottle samples collected aboard the USCGC Healy and R/V Sikuliaq during cruises HLY1301 and SKQ201505s, respectively, in the Bering Sea and Chukchi Sea between 2013-08-03 and 2015-04-03. These data were collected by Christopher R. Paver (NCEI) and Dr. Louis A. Codispoti (UMCES) conducting research on bottle flushing protocol. These data were submitted by Christopher R. Paver.

This dataset contains water temperature, salinity, and other parameters taken by CTD during the 2018 Bering Strait mooring cruise. Data are in CNV format. The cruise was funded by the NSF-Arctic Observing Network grants: - PLR-1304052 (PIs: Woodgate, Heimbach and Nguyen), and - PLR-1758565 (PIs: Woodgate and Peralta-Ferriz). The data are from a ~ 10 day cruise on the US vessel Norseman II from 2018-08-10 to 2018-08-19 sailing from and to Nome, Alaska, USA to the Bering Strait and the Southern Chukchi Sea. The cruise was also to service oceanographic moorings in the strait and those data are archived separately. A total of 142 casts were taken and are included in this archive. No water samples were taken during this cruise. Stations were taken in US waters near mooring locations and on sections in the Bering Strait and southern Chukchi Sea. See cruise report for map, station locations, calibration, and processing details. The data are taken using an SBE911p system, recording pressure, temperature (dual system), conductivity (dual system), oxygen (dual system), fluorescence, and turbidity.
