Nancy Knowlton, Smithsonian's Sant Chair for Marine Science, puts up an Autonomous Reef Monitoring Structure (ARMS) during a dive in the Red Sea. These small underwater “condos” have been placed across the world’s oceans—from shallow water to 700 feet on the deep reefs of Curaçao, and from Brazil to the Indian Ocean. The ARMS mimic the nooks and crannies of oyster reefs, without the sharp edges...Read more

Deep-sea corals miles away from the source of the Deepwater Horizon oil spill in 2010 were impacted by the plumes. One affected site was 13.7 miles (22 km) away from the Macondo wellhead—the farthest observed—and extremely deep, more than 6,000 feet (1,875 meters) below the surface. This is deeper than any of the reported oil plumes that resulted from the spill. How did oil get down there? Read...Read more
