NOAA Tech. Report ERL 191-POL5, 9 pp (1970)


This report presents the paths of seven parachute drogues tracked in the North Pacific Ocean during 1961 and 1962. In the Alaskan Stream near 161°W, four drogues moved in a clockwise gyre in agreement with meanders in the Stream suggested by other data. A drogue farther east in the Stream moved at 36 cm/sec, 240°t. A semidiurnal flow of about 10 cm/sec was superimposed on the net flow. Two drogues near 27°N, 160°W drifted southwest at speeds in excess of 25 cm/sec, and there is some suggestion of periodic motion in the paths.
