A series of oceanographic studies was performed off the southeast coast of the United States, combining data from the NOAA-2 and NOAA-3 satellite and from the Cape Fear Technical Institute, RV DALLAS HERRING and RV ADVANCE II. The phenomena studied consisted of short-period intrusions of shelf water into the Gulf Stream and a cold eddy on the east side of the Gulf Stream. The satellite data were used to identify and locate these perturbations in realtime, and to define the sea-surface temperature distribution associated with the perturbations. The location data obtained from the satellite imagery were used to plan an oceanic field program using a ship to collect temperature and salinity data in the perturbation. The integration of satellite data with in-situ data yielded some rather interesting aspects of the physical structure of both phenomena studied. The most significant contribution of the satellite data was the capability of these data to provide an instantaneous, near-synoptic view of the sea-surface temperature pattern that brought to light factors that could have never been identified by the in-situ data alone.
