In this way the darker features in the lee of the islands show up as lighter areas which seem to bring out small changes in lower density. Fig. 1 is a mosaic of negative prints for 13-14 October in each of the four MSS bands: ERTS band MSS 4 MSS 5 MSS 6 MSS 7 A (Mm) MSS 5 seems to have the optimum sensitivity for de- tecting these ocean features. The changes in photo density are much more clearly defined in MSS 5 than they are in MSS 4 and slightly clearer than MSS 6 and MSS 7. 3. ERTS-1 data interpretation a. ERTS photographic data Fig. 2 shows the ERTS-1 coverage of the area west of Martinique. Although much of the region is covered with cirrus and small cumulus clouds, two lighter areas are visible near the top of the print. A narrow line ex- tends to the southwest in the lee of the northern tip of Martinique. Another light feature can be seen at the top edge of the negative print to the northwest of Martinique which also extends in a southwest direction parallel with the feature at the northern tip of the island. This feature appears to be originating from the western side of Dominica. Figs. 3 and 4 show the data received for the 13-14 October and 19 November orbits, respectively. In the October data, bright areas can be seen to the west of all the islands from Guadeloupe to Grenada and Tobago. The brightest area is to the west of St. Vincent. The features extend in a west to west-northwest direc- tion away from each island. On 19 November, only moderate indications of ocean featur
