Abstract
  • Currents between the surface and 1000 m depth off the Oregon coast have been measured by tracking parachute drogues. The study was initiated by Mr. Bruce Wyatt in January 1962, using the R/V ACONA. Dr. Paul M. Maughan participated in the earlier half of the work and wrote his master's thesis on part of the results (Maughan, 1963). Acquisition of the R/V YAQUINA in October 1964 made possible improved handling and much more precise radar fixing. Dr. Merritt Stevenson made thorough analyses of these data and of associated dye studies for his doctoral dissertation (Stevenson, 1966). A paper summarizing the results and discussing tidal and inertial periodicities in the data is being prepared for publication (Stevenson and Pattullo, in preparation). We are deeply indebted to Mr. Tim Noland, who, with Mr. Wyatt, designed and fabricated both the drogues and the anchored buoys, and who also took part in most of the cruises. This report contains plots of all drogue trajectories and mean velocities, tables of identifying data and wind observations, and listings of programs used in processing the data.
