In previous Gulf Stream work (Hall and Bryden, 1985, Hall, 1985, 198GA, 198GB), a decomposition of multiple depth current records was developed which produced along- and cross-stream components. The cross-stream component was found to occasionally match lateral displacements of the Stream, as determined by temperature changes measured at the current meters. This study determined where within the meander pattern of the Gulf Stream the cross-stream velocity calculated from current meters at depth correctly predicted translations of the Gulf Stream as measured by satellite data. Additionally, the effects of recently quantified cross-stream velocities associated with the curvature of Gulf Stream meanders were analyzed.
