Methane Zit



From Clastic Detritus: Sea-Floor Sunday #22: A actively-growing mound on the sea floor (Hat tip: Anaconda)

A paper came out in Marine Geology last month (v. 250, p. 258-275) about a methane-seeping, actively-growing sea-floor mound in Santa Monica Basin (offshore Los Angeles, CA).

It’s like a zit on the sea floor!!
Here is the abstract: Association among active seafloor deformation, mound formation, and gas hydrate growth and accumulation within the seafloor of the Santa Monica Basin, offshore California.

Continuous streams of methane gas bubbles emanate from the crest of the northeastern mound, and extensive methane-derived authigenic carbonate pavements and chemosynthetic communities mantle the mound surface.
