Drift cards were released in Monterey Bay, California, to detect seasonal variations in the California Current system, and seasonal and diurnal wind variations in the immediate vicinity of the bay. About 23% of the cards were recovered, although the recovery rate varied from about 5% in the winter to about 60% in the late summer. Drift card speeds ranged from 1 to 8 km/day, in the winter and summer months respectively. Good agreement was observed between geostrophic current, wind, drogue, and drift card data, although drift cards were observed to be primarily wind driven. A weekend bias in drift card recoveries was observed for the entire period of study; however, it was less pronounced for those cards released during the summer months. Two bogus releases were used to estimate the discovery lag time, reported position accuracy, and longshore drift currents. Diurnal winds were observed during a 24-hour study, and indicated daily variations in the wind field may be as important as seasonal changes in moving surface water. The drift card speed was observed to be about 3% of the wind velocity, and 1 m/sec was estimated as the minimum effective wind. The wind factor, ranging from 2.2% to 4.0%, was used to estimate the actual paths of drift cards and to examine the role of diurnal winds in affecting surface water movement. (PDF contains 79 pages)

This report completes the hydrographic data series obtained during 27 monthly oceanographic cruises in Monterey Bay. This oceanographic study was initiated under a grant from the Office of Sea Grant Programs, and the data collection began in February 1971. In September 1971 additional funding was received from the Association of Monterey Bay Area Governments. The data obtained during 1971 have been published previously (Broenkow 1972), and some initial interpretation of this work has been reported by Smethie (1973), Broenkow and Smethie (1973), and Oceanographic Services, Inc. (1973). (PDF contains 336 pages)
