This entry contains CTD data from the National Ocean Service, Rockville, MD circulation survey of Willapa Bay and Grays Harbor, Washington. These data were collected from May to July 1982 using NOAA Ship McARTHUR. Salinities and times are not included in this data set. Data were collected with an Aanderaa RCM4 current meter and PLESSEY 9041 and APPLIED MICROSYSTEM #12 CTD's. Data were collected in association with NOAA Operation #OPR-N-802-AR-82. Data has been processed by NODC to the NODC standard High-Resolution CTD/STD (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.
