Description:Description is given of the experiment and of the movements of 77 thin, floatable drifters (1.3 x 1.3 x 0.0032 m) launched at 1/4 - 1 mile intervals cross channel from Pillar Point in the Outer Strait of Juan de Fuca during 19-23 July 1977. Provided herein are positions, velocities, trajectories, and spatial vector diagrams for six to eight hour intervals during which drifter positions were observed several times per hour. An apparent net cross channel drift toward U.S. was observed, with shore recoveries high in Clallam Bay and in the lee of Pillar Point, suggesting these as possible entrapment areas. The cross channel drift appears highest on flood tides concurrent with westerly winds.
