The Quinault Canyon II Project September 1980–January 1981

The Quinault Canyon II Project was sponsored by the United States Department of Energy Contract DE-AT06-76-EV-71025 to Dr. B. Hickey at the University of Washington. The study of circulation in and around canyons is important to the Washington coast since several canyons are located in this area. Astoria and Quinault Canyon provide the primary conduits by which land derived sediments and pollutants reach the deep ocean.

The University of Washington maintained 9 current meter moorings, QC801 through QC8010 (QC806 was not deployed) in and around Quinault Canyon. Current meters were all Aanderaa (AA) instruments. Speed and direction and temperature were measured by the Aanderaa meters. Data was sampled in 20 minute intervals, then edited for spurious values. Speed and direction were independently filtered with a 5 point binomial filter spanning approximately 1.5 hours then resolved into u and v components.

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, ºC,
Pressure, P, decibars,
Date and time is listed as DATE. Add 8 hours to get GMT, format is mm/dd/yy hh:mm.

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 QC802u252 indicates the data is from the QC802 mooring, u component at 252m, QC805T395 indicates the data is from the QC805 mooring, temperature data at 395m. The last column, JJ, is zero filled to indicate last data column for that meter.
