Scripps research vessel Roger Revelle probes seabed off Alaska

The ROV and sonar explorations revealed a complex set of environments on the Alaskan margin, including deep canyons, steep scarps (walls), sandy slopes and an unusual seamount. While exploring the area, the scientists also discovered previously unknown cold methane seeps and biological communities that exist in such environments. The seeps, found 3,300 meters below the water’s surface, were unlike others that have been studied on the Pacific margin.
