Deepwater Horizon : la marée noire du siècle. Gulf Oil Slick Approaching Loop Current. During the first weeks following the explosion at the Deepwater Horizon well in the Gulf of Mexico, oil drifting from the site of the incident usually headed west and northwest to the Mississippi River Delta. But in the third week of May, currents drew some of the oil southeast.
According to the National Oceanic and Atmospheric Administration (NOAA), the southward spread increased the chance that the oil would become mixed up with the Loop Current, which might carry the oil toward Florida and the Keys. This pair of sea surface temperature images shows how the warm waters of the Loop Current connect the Gulf of Mexico to the Atlantic Ocean (top image, May 1–8, 2010) and the dynamic northern margin of the Loop Current a week and a half later, on May 18 (bottom image).
The Loop Current pushes up into the Gulf from the Caribbean Sea. The current’s tropical warmth makes it stand out from the surrounding cooler waters of the Gulf of Mexico in this image. Instrument(s): Aqua - MODIS. Keeping up-to-date on the Gulf of Mexico oil spill. It is estimated that at least 6 million gallons of oil have leaked into the Gulf of Mexico since the Deepwater Horizon explosion a month ago.
Cleanup efforts are underway, but the oil has spread extensively around the Gulf and along the southern U.S. coastline. Oil has begun washing up on the beaches of Louisiana and the delicate wetlands along the Mississippi River, and can spread to Florida and throughout the Gulf as weather conditions change. This sequence of images, coming from NASA’s MODIS satellites, illustrates the movement and growth of the oil slick over the past few weeks: April 25, 2010 April 29, 2010 May 9, 2010 May 17, 2010 The last image, taken earlier this week (on May 17), shows the coastal areas currently at risk from the spreading oil, and can help those working on the wide range of relief efforts.

Nearly a month after a deadly explosion at the Deepwater Horizon oil rig, the damaged well on the bottom of the Gulf of Mexico continued to spill oil.
In the weeks since the accident occurred, the oil slick has periodically drifted northeast toward the Mississippi Delta and reached the Chandeleur Islands. On May 17, 2010, when the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite acquired this natural-color image, a large patch of oil was visible near the site of the accident, and a long ribbon of oil stretched far to the southeast. Oil slicks are not always visible in natural-color satellite images. A thin sheen of oil on an already dark background may be impossible to detect. Sunglint is the mirror-like reflection of the Sun off the water. A coating of oil smoothes the sea surface relative to the oil-free water, causing it to reflect light differently.
