摘要

Abstract

Sub-tidal (1.04–25 day) current fluctuations during winter/spring on the continental shelf off Savannah

Georgia (32°N) and off St. Augustine

Florida (30°N) were compared with records of local wind stress components and GulfStream position. (Acoustic travel time and bottom pressure measurements at stations on the continental slope were combined to determine main

thermocline depth

as an indicator of Gulf Stream displacement). Relative wind influences increased towards the coast. GulfStream influence increased towards the shelf-break and towards the surface. Off Savannah

the Gulf Stream influence was predominately at 12 day period and was negligible at the 45 m isobath. Off St. Augustine

its influence was predominately at 4 day period and was appreciable at the 40 m isobath (but negligeable at the 28 m isobath). Linear predictions of currents from wind and Gulf Stream account for ∼80% of the observed variance. Similar methods of studying and predicting the wind—and Kuroshio-influenced currents on the East China Shelf are proposed.
