Exploration Note. When NOAA Ocean Exploration explored the Musicians Seamounts, north of the main Hawaiian Islands, they found a high diversity of organisms living on the seamount and in the water column. Scientists including zoologists, ecologist, engineers, and oceanographers explored the midwater, a part of the ocean deeper than 200 meters, with remotely operated vehicle Deep Discoverer. The midwater is the largest habitable region on Earth for multicellular life forms. Learn about how the mission team explored this vast region of the ocean and the organisms they discovered from the scientists themselves.
