The Marineland Experiment was conducted in the Atlantic shelf region offshore of Marineland, Florida, during the month of December 1975. The dual objectives were: (1) to investigate the mechanisms of wave imaging by the synthetic aperture radar and (2) to investigate wave transformations at the western boundary of the Gulf Stream and across the continental shelf to the edge of the surf zone. Three aircraft, two equipped with synthetic aperture radars and one with a real aperture system, participated in the experiment. Three instrumented sites in 10-m, 20-m, and 60-m water depths were incorporated as surface truth. These corresponded to 1 km, 27 km, and 100 km offshore, respectively. This overview captures the mesoscale aspects of the Marineland Experiment and provides a summary of the salient results. For detailed presentations and analyses of the data collected, the reader should refer to the individual papers.
