Image supplied by the ATSR instrument on board ESA's ERS-2 satellite which shows details using the infrared and 11 micron channel. The plume of smoke is very evident in the image due to the temperature difference between the smoke and the sea. Interestingly, the smoke is cooler than the sea in much the same way as the wake that follows a jet aircraft.
