ASAR Product for May 2, 2010 (IMAGE) European Space Agency Caption In this Envisat Advanced Synthetic Aperture Radar (ASAR) product for May 2, 2010, advanced processing methods have been performed to display ocean surface roughness variations and Doppler-derived ocean surface radial velocities around the oil spill area in the Gulf of Mexico. As visible, the spill still appears relatively confined around its point of origin and is still north of the Loop Current. An intriguing shape is detected in the image that seems to passively follow the flow derived from the Doppler measurements.
