Temperature profile, current, pressure, physical, and other data from XBT casts, current meters, pressure gauges, and CTD casts from the VEGA I and other platforms from the Coastal Waters of California and other locations as part of the Central California Circulation Study from 1984-01-31 to 1985-07-01 (NCEI Accession 8700197)

Temperature profile, current, pressure, physical, and other data from the VEGA I and other platforms from the Coastal Waters of California and other locations from 31 January 1984 to 01 July 1985. Data were collected by the Raytheon Co. as part of the Central California Circulation Study. Data were processed by NODC to the NODC standard Universal Bathythermograph Output (UBT) format, the F015 Current Meter Components format, the Pressure Gauge Data format, and the High-Resolution CTD/STD Output Format.

The UBT format contains temperature-depth profile data obtained using expendable bathythermograph (XBT) instruments. Cruise information, position, date and time were reported for each observation. The data records are comprised of pairs of temperature-depth values. The XBT data files contain temperature values at non-uniform depths. These depths were recorded at the minimum number of points ("inflection points") required to accurately define the temperature curve. Standard XBTs can obtain profiles to depths of either 450 or 760 m. Special instruments permitted measurements to be obtained to 1830 m.

The F015 format contains time series measurements of ocean currents. These data are obtained from current meter moorings and represent the 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 includes 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. 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 F017 format contains time series measurements of seawater pressure from anchored or bottom-mounted sensors. Measurements of variations at depth of seawater pressure provide information on tidal and storm flows, ocean circulation, and other phenomena that cause changes in sea surface elevation or slope and that can be detected from their pressure signature. Position, bottom depth, and gauge depth are reported for each station. The data record comprises values of total pressure at specified date and time. Data values may be subject to averaging or filtering and are typically reported at time intervals of 10-15 minutes. Seawater temperature may also be reported. Comments may be reported in a text record.

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.
