Samples of surface water were collected from both slick and nonslick areas of the Bay of Panama by the screen method developed at NRL. Analysis in dicated that both slick and non-slick covered surface waters contain a similar mixture of sur face-active chemicals. Extracted substances were identified as fatty acids, lipids, and nonpolar hydrocarbons, with some chemical unsaturation showing in the hydrocarbon portion of the organic molecules. The isolated material forms compressi ble, liquid-expanded films on water which appear to contain quantities of nonpolar material. Sur facosities of the films were low, indcative of appreciable amounts of unsaturated fatty acids and esters. Gas chromatographic studies showed that each sample contained a complex mixture of saturated and unsaturated fatty acids containing from 8 to 20 carbon atoms. An average of approx imately 16 carbon atoms per molecule was found.
