On the second anniversary of the Deepwater Horizon blowout, a national panel of researchers is urging the US federal government to reassess how it would respond to similar oil spills that might occur in the future.

On the second anniversary of the Deepwater Horizon Oil Spill, a pair of researchers are testing whether sound waves can be used to determine the size of oil droplets in the subsea—knowledge that could help guide the use of chemical dispersants during the cleanup of future spills.

Researchers have found that the submarine volcano of El Hierro (Canary Islands) continues expelling gases, which are primarily carbon dioxide. No sulfur compounds were detected.
