Eastward and northward components of ocean current, water temperature, and others collected from moorings in North East Pacific Coast from 1977-10-07 to 1978-10-29 (NCEI Accession 0163986)

As part of this project the University of Washington maintained 2 current meter moorings, Ocelot (OC) and Elephant (EL), from Oct. 1977 through Oct. 1978 across the continental slope at 45-20º N off Cascade Head on the Oregon Coast. All current meters were Aanderaa instruments. Speed and direction were measured and rotated to true North, then resolved into u and v components. All meters had temperature sensors. Data was sampled in 20 minute intervals, edited for spurious values then filtered with a half power point of about 2.5 hours and interpolated to even hours to produce the hourly data. In several cases the speed sensor failed for short periods. These were filled by bridging the gap using spectral characteristics before and after the gap. For longer time periods the speed, u and v series were zero filled. Occasionally the entire speed series was not good. In those cases only the direction is included. Results from this study can be found in: Hickey, B.M. (1984) The fluctuating longshore pressure gradient on the Pacific Northwest shelf: A dynamical analysis. Journal of Physical Oceanography, 14: 276-293. Huyer, A., R.L. Smith and B.M. Hickey (1984) Observations of a warm-core eddy off Oregon, January to March 1978, Deep-Sea Research, 31: 97-117.
