Moored current meter and wind recorder measurement near Point Conception, California: The 1983 OPUS Observations, from 1983-04-01 to 1983-07-29 (NCEI Accession 8600041)

The OPUS (Organization of Persistent Upwelling Structures) program deployed two current meter (VMCM) moorings near Point Conception, California, during April - July 1983. Current and temperature data from these moorings are summarized here. In addition, data from two nearby NDBC (National Data Buoy Center) meteorological buoys are presented. Data were processed by NODC to the NODC standard Current Meter Data (F015) format. Full current meter moorings descriptions are available at http://www.nodc.noaa.gov/General/NODC-Archive/f015.html.

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.
