Abstract

During two experiments monitoring ocean dumping operations in the Gulf of Mexico and off Arecibo, Puerto Rico, a number of drifters were tracked with a ship-borne radar and aerial photographs of the plumes were analyzed by use of the results of drifter experiments in the Gulf of Mexico. Horizontal eddy diffusivity was determined from increases of the variances of the drifter positions with time and were calculated with Okubo’s method (1976). The variances of drifter positions did not increase with time when the wind speed exceeded critical values off Puerto Rico. It was speculated that the wind rows caused the drifter convergence during the Puerto Rico experiments. The speculation is partially confirmed by analyzing the aerial photos of the plumes which show striations along the direction of the prevailing winds.
