Atlantic Ocean

The dark streak curving northeast across the Atlantic Ocean in this Moderate Resolution Imaging Spectroradiometer ( MODIS ) image is probably not significantly darker than the surrounding ocean water. Its appearance is likely to be a trick of light. The rest of the ocean is bright and silvery because of sunglint—a phenomenon that occurs when the suns light is reflected off a smooth surface into MODIS “eye.” The dark water is probably rough, so it does not reflect the light like the surrounding ocean water. The surface roughness may be related to the Gulf Stream, the northern boundary of which is near the region of dark water. The calmer waters to the south are in the lee of the Carolina coast. This image was acquired on April 29, 2004, by MODIS on NASAs Terra satellite.
