Deepwater Horizon: Images of an Impact
Alvin Explores the Gulf
The Deep Submergence Vehicle Alvin is shown working at the coral site found to be impacted by the oil spill from the Macondo well in the Gulf of Mexico. Compelling evidence of the impact of the Deepwater Horizon oil spill on deep-sea corals will be published online in the early edition of the journal Proceedings of the National Academy of Sciences during the week beginning March 26, 2012. The researchers, led by Penn State University Biologist Charles Fisher, used a wide range of underwater vehicles, including the research submarine Alvin, as well as comprehensive chemical-analysis techniques to determine precisely the source of the petroleum hydrocarbons they found on the corals.

A portion of one of the impacted corals and two attached brittle starfish. Living tissue is orange and most of the skeleton is bare or covered by brown flocculent material. The brittle starfish are normal symbiotic partners of this type of coral. The brittle star on the left shows a more normal coloration for this species and the individual on the right is bleached white and much more tightly wrapped around the branch than normal. Both starfish were uncharacteristically immobile.
One of the impacted corals with attached brittle starfish. Although the orange tips on some branches of the coral is the color of living tissue, it is unlikely that any living tissue remains on this animal.

Gulf Oil Spill Spread Seen from Above
On May 9, 2010, oil continued to flow from a damaged offshore oil well in the Gulf of Mexico. This image from the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Aqua satellite shows the slick on Sunday afternoon.

Oil Spill Seen Approaching Shore from Space
In this image acquired by ESA's Envisat on April 29, oil from the massive spill in the Gulf of Mexico can be seen as a dark blue swirl advancing toward the Louisiana coast. Envisat acquired this image with its Medium Resolution Imaging Spectrometer (MERIS). Credits: ESA
Gulf Oil Spill Update: Just the Facts
A Brown Pelican prepares to enter the water at the Egmont Key National Wildlife Refuge near St. Petersburg May 23, 2010. The bird was rescued and cleaned by U.S. Fish and Wildlife Service after being found oiled near Louisiana's coast.

The pelican was successfully netted and transported to a facility on Grand Isle, La., for stabilization before being taken to Fort Jackson Oiled Wildlife Rehabilitation Center in Venice, La., for cleaning.
