Image : Microbiology and Biogeochemistry of Autotrophic Microbes in the Subsurface at Hydrothermal Vents: Filamentous-Sulfur Producing Bacteria

Flocculent discharges comprised of filamentous sulfur and associated microbes, and referred to as "snowblower vents", have now been documented at several deep sea hydrothermal vent sites. Pictured above (photo courtesy of Dr. D. Fornari, WHOI) are emissions occurring during the 1991 volcanic eruption along the East Pacific Rise at the 9N vent site when this type of intense discharge from the vent subsurface was first documented.
