The non-tidal circulation in Rhode Island Sound shows seasonal variations at both the surface and bottom. During spring, the surface drift is primarily toward the east and north, while the bottom drift is toward the northwest. During summer, the surface drift tends northerly, with secondary components toward the east and west, reflecting the effect of a cyclonic eddy. Bottom drift during the summer is similar to that observed during the spring. During autumn and winter little data were obtained during the winter season, the surface drift tends offshore, while the bottom drift tends onshore. The features of the drift patterns are discussed in the light of river effluent, advection, and meteorological effects. Typical drift speeds were from 0.1 to about 3 kmday. Based on the seasonal pattern and other persistent features of non-tidal drift, a test firing area is suggested that offers the best probability for ultimate recovery of a lost test vehicle. Author
