Scientists discover pristine deep-sea coral reefs
Observations using the newly upgraded human-occupied vehicle Alvin are the first of a deep-sea coral reef in the Galápagos Marine Reserve. The reef, found at 400-600 meters (1,310-1,970 feet) depth at the summit of a previously unmapped seamount in the central part of the archipelago, supports a breathtaking mix of deep marine life, Woods Hole Oceanographic Institution writes.
