The University of Alaska, Institute of Marine Science is responsible for this data collected aboard the R/V Alpha Helix on cruise number HX90 between 2022 17-Sep-1986 to 25-Sep-1986 by Dr. R. Tripp of the Department of Oceanography, University of Washington. There was a total of 43 stations in the Bering and Chukchi Sea area. The station numbers are: 1-43. Data has been processed to the NODC standard High-Resolution STD/CTD Data (F022) 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.

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.
