Gulf of Mexico Oil Spill’s Effects on Deep-Water Corals

*Damaged deep-sea corals discovered months after Deepwater Horizon spill*

Scientists are reporting new evidence that the Deepwater Horizon oil spill has affected marine life in the Gulf of Mexico, this time species that live in dark ocean depths–deepwater corals.

The research used a range of underwater vehicles, including the submarine Alvin, to investigate the corals. The findings are published this week in the journal Proceedings of the National Academy of Sciences (PNAS). (more…)

Scientists Study Earthquake Triggers in Pacific Ocean

*Samples of rock, sediment from beneath the sea-floor help explain quakes like Japan’s*

New samples of rock and sediment from the depths of the eastern Pacific Ocean may help explain the cause of large, destructive earthquakes similar to the Tohoku Earthquake that struck Japan in mid-March.

Nearly 1,500 meters (almost one mile) of sediment cores collected from the ocean floor off the coast of Costa Rica reveal detailed records of some two million years of tectonic activity along a seismic plate boundary. (more…)
