Abstract : Progress during the past year was primarily in the development of an offshore measurement capability and the initial stage of data collection in the regio adjacent to Tomales Bay. Preliminary analysis indicates that several cycles of coastal upwelling having a period of five to six weeks, were observed by sequential measurements during the fall and winter months of 1969-1970. A low-cost operational capability has been achieved for the study of detailed density structure of shelf waters. Results not only provide some understanding of the processes affecting Tomales Bay, but indicate a possible relationship of the density structure to the movements of commercially important fish in the area.
