Caption from Oceanus online article:
Hot, buoyant, mineral-laden fluids rise from deep within ocean crust and mix with cold seawater. That triggers the precipitation of minerals that form deposits near and on the seafloor. Precipitating minerals also form seafloor "chimneys," and mineral particles in the fluids venting at the seafloor make the fluids look like smoke.
Image Of the Day caption:
Hydrothermal vents are famous for chimneys that belch hot, mineral-laden water from deep beneath the ocean floor. Not all the fluid at vent sites flows so dramatically, though. Some diffuse through the seafloor in regions like the one shown here, photographed from above by the remotely operated vehicle Jason. Join us in January for Dive & Discover cruise 15, as WHOI scientists Stefan Sievert and Jeff Seewald lead an international team investigating the microbial life and ecology of diffuse-flow areas and the subseafloor at the 9 North vent site in the Pacific.
