A Study on Hydrographic Conditions and Salt Budget Calculation for the Gulf of Farallones with the Data Collected in August 1990

Abstract

The circulation pattern observed in the Gulf of Farallones on 5-10 August 1990 was a cyclonic system of flow. Water entered the Gulf from south of the Farallon Islands and left the Gulf between Pt. Reyes and the Farallon Islands. This pattern is confirmed by a satellite image which indicates a tongue of warm water penetrating into the Gulf from offshore as well as the increasing salinity and density along a shallow salinity minimum in this area. This cyclonic flow was also observed by previous current meter moorings in and near the Gulf. Note that this circulation would provide a return flow to balance offshore flow which has been observed at Pt. Reyes.
