|Researching the effects of underwater hydrothermal venting systems|
|Marianas Submarine Volcanoes|
In February 2003, the Vents Program conducted an extensive survey of the submarine volcanoes in the Mariana Arc (funded in part by NOAA's Ocean Exploration Program). This expedition included detailed mapping of the seafloor and a search for indications of hydrothermal venting at each volcano. It was found that about 20% of the Marianas submarine volcanoes were hydrothermally active. A follow up expedition with a remotely operated vehicle will investigate these sites on the seafloor.
