Physical, meteorological, wave spectra, and other data from CTD casts and current meters aboard NOAA Ship McARTHUR in the Columbia River (Washington/Oregon) from 1981-05-06 to 1981-11-25 (NCEI Accession 8300033)

Physical, meteorological, wave spectra, and other data were collected from CTD casts and current meters from NOAA Ship McARTHUR and other platforms in the Columbia River (Washington/Oregon). Data were collected by the National Ocean Service (NOS) from 06 May 1981 to 25 November 1981. Data were processed by NODC to the NODC standard F022-High-Resolution CTD/STD Output and the F191-Meteorology and Wave Spectra formats.

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 F191 format is used to report meteorological data and ocean wave spectra data from NDBO. The format contains seven data record types to: 1) identify the buoy for position, duration, rate of sampling and heading, 2) identify the meteorological parameters, (temperature, pressure, weather, solar radiation, and surface waves), and 3) report time times series frequency, density and resolution of waves. Each record is 120 character in length, sorted by station and record type.
