Abstract : From July 1972 to February 1973 a number of experiments were carried out in the vicinity of Ambrose Tower, designed to study the velocity field in the upper few meters of the water column and dependence of local environmental factors. The experiments consisted of aerial photography of a pattern of dyed water, free drifters, dye plumes from anchored generators, drogues set at 1, 3, and 5 meters and floating computer cards. Also photographed were the acid-iron discolored water patters farther off the coast which enabled large-scale study. The basic aim of the set of experiments is to better understand the fate and behavior of oil contamination. Oil split on the ocean does not spread laterally in a uniform way, but responds to the basic velocity field of the upper few meters (and may, in turn, influence the velocity field directly).
