These features are part of the Gorda Ridge, a tectonic spreading center located off the border of California and Oregon. The Newly Discovered Apollo Vent Field. Via the SUBSEA (Systematic Underwater Biogeochemical Science and Exploration Analog) Research Program.

stay for the vent naming.
is that what the kids are calling it these days
That Apollo Vent Field video, with all the hot water gushing out, makes me wonder where the tube worms are. Not the right mix of minerals dissolved?

Tube worms eat hydrogen sulfide (or rather the bacteria inside them do). I don't think these vents have much sulfides. If they did, you'd see it precipitating out as black crud when the superheated water mixed with cold ocean water.

Looks like in the southern part of the Gorda Ridge there are massive sulfide deposits in the Escanaba Trough, rich in copper, gold, silver and other metals -- and a home to tube worms.
