Hydrothermal mound in the Guaymas Basin

Caption

Photo 1: Hydrothermal mound at ~2000 meters depth in the Guaymas Basin. This several meter tall "living" tower of hydrocarbon-soaked minerals and sediments is permeated by hydrothermal fluids. The surface of the structure is covered with white and orange mats of bacteria that use sulfur as an energy source. Seen from the submersible Alvin.
