CTD, primary production, and underway data from THOMAS G. THOMPSON in the Bering Sea from 1978-04-10 to 1981-07-21 (NCEI Accession 9100027)
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.
