Deep-sea hydrothermal vents more abundant than thought

Science News, June 2016

The deep, dark ocean bottom teems with far more oases of life than once thought. Searching along the sunless seafloor where tectonic plates pull apart, regions known as spreading ridges, researchers discovered that heat-spewing hydrothermal vents are at least three to six times as abundant as previously assumed. The finding also significantly boosts the likely number of marine ecosystems huddled around vents, the researchers report in the Sept. 1 Earth and Planetary Science Letters.
