The Continental Shelf Experiment 1972

The Continental Shelf Experiment was sponsored by the U. S. Atomic Energy Commission under contract designator AT 45-1-2225-TA-25 to Dr. J. Dugan Smith, Principal Investigator, at the University of Washington.

Beginning in 1972 the work for the Energy Research & Development Administration was expanded to keep moorings out for longer time periods during the winter and summer and to maintain moorings at both an Inshore and an Offshore site. In 1972 the University of Washington maintained 2 current meter moorings, Inshore, (IN), and Offshore (OF) during January, July, and August 1972. In addition, a joint project with the Pacific Oceanographic Laboratory of the National Oceanographic and Atmospheric Administration (NOAA) was completed in September 1972 and provided a two-month record of temperature and currents over the Washington continental shelf and slope at three moorings (S6, S8, S11). During this period similar observations were made by the Coastal Upwelling Experiment (CUE) over the Oregon shelf. These two data sets, one off Washington, the other off Oregon, resulted in a better understanding of continental shelf processes.

Current meters used were Aanderaa model RCM-4 (27), Braincon type 381 (20) and 3 vector averaging current meters (VACM). The Aanderaa and Braincon instruments belonged to the University of Washington, while the VACM instruments belonged to NOAA. The Aanderaa and Braincon current meters measured speed and direction, which was then resolved into u and v components. The Aanderaa meters had temperature sensors. Aanderaa meters sampled at 10 minute intervals, Braincons sampled at 10 or 20 minute intervals, and the VACM meters sampled at 3.75 minute intervals. Data presented below has been edited for spurious values. A more complete description of the data can be found in: Smith, Hickey, Beck, 1976, Observations from moored current meters on the Washington Continental Shelf from February 1971 to February 1974, University of Washington, Department of Oceanography, Special Report 65.

Abbreviations and units are:
Depth, m, meters,
Speed, spd, cm/sec,
Direction, D, degrees, true north,
u component (eastward), u, v component (northward), v, cm/sec, true North,
Temperature, T, º C,
Date and time is listed as DATE to indicate time is in Pacific Standard Time, format mm/dd/yy hh:mm. Add 8 hours to convert to Greenwich mean time (GMT). Recovery and deployment information is in PST unless the time is followed by 'z' to indicate it is in GMT.
Date and time is listed as GDATE to indicate time is in GMT, format mm/dd/yy hh:mm. The data from the S6, S8, and S11 moorings are in GMT. Recovery and deployment data are in GMT denoted by a 'z' after the time.
Aanderaa current meter, AA
Braincon current meter, BR



Data files consist of ASCII tab delimited files, one per meter. Headers indicate the time base, mooring, the deployment, variable, and depth rounded to the nearest meter. For example, IN1u15 indicates the data is from the IN mooring, first deployment in 1972, u component at 15m, OF3v23 indicates the data is from the Offshore mooring, third deployment in 1972, v component at 23m. The last column, JJ, is zero filled to indicate the last data column for that meter.
