The Continental Shelf Experiment 1971

The Continental Shelf Experiment was sponsored by the U. S. Atomic Energy Commission under contract No. AT(45-1)-1725, TA 25 to Dr. J. Dugan Smith, Principal Investigator, at the University of Washington.

The purpose of the 1971 project was to obtain full vertical profiles during all seasons from the same station on the central shelf. For this project the University of Washington maintained 1 current meter mooring, Inshore, (IN), during February, July and October 1971. An offshore mooring, (OS), was added in October.

Most of the current meters used were Braincon type 381 (14), but 5 Aanderaa model RCM-4s were introduced on the October moorings. Speed and direction were measured, then resolved into u and v components. The Aanderaa meters had temperature sensors. Data was sampled in 10 minute intervals and 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 GMT.

Data files consist of ASCII tab delimited files, one per meter. Headers indicate the mooring, the deployment, variable, and depth rounded to the nearest meter. For example, IN171u15 indicates the data is from the IN mooring, first deployment in 1971, u component at 15m, OS371v23 indicates the data is from the Offshore mooring, third deployment in 1971, v component at 23m. The last column, JJ, is zero filled to indicate the last data column for that meter.
