Dynamic topography estimates were obtained for the Gulf Stream region employing a previously derived synthetic geoid and Geosat radar altimeter measurements. Ascending tracks passed through the central and eastern arrays of the Synoptic Ocean Prediction experiment. By utilizing the geoid estimate instead of the mean altimetric signal, the axis position and velocity can be computed. A time series of the dynamic height profiles crossing the Gulf Stream and a table of the positions of the axis of the Stream along two tracks are given. Time series of the maximum velocity perpendicular to the ground track were computed for both arrays. It was found that there was a seasonal cycle in this time series with a maximum in November.
