250-meter resolution MODIS true color and false color Red\/Green\/Blue (RGB) images from the SSEC MODIS Today<\/a><\/strong> site (above)<\/em><\/strong> showed that the oil slick resulting from the offshore oil rig fire and collapse (following an explosion on the night of 20 April 2010<\/a><\/strong>)<\/em> continued to get closer to the coast of Louisiana on 29 April 2010<\/a><\/strong>. Along the far western edge of the oil slick, a small smoke plume can be seen drifting northeastward, due to a small controlled burn (the winds were from the southwest at altitudes of about 1 km and higher)<\/em>.<\/p>\n

A comparison of MODIS true color images on 21, 22, 25, 29 April, and 01 May (below)<\/em><\/strong> show the original smoke plume from the burning oil rig, followed by the dramatic growth and change in shape of the oil slick during that period.<\/p>\n
