SECRETS OF THE GULF EXPEDITION, MARCH 2007--MUD VOLCANOES
Following are images taken by the ROV Argus during the Secrets of the Gulf Expedition. These images show a couple of different mud volcanos that were visited during the course of the expedition. Instead of magma, methane gas is bubbling up through the sea floor. The resulting cone of sediment resembles a volcano, hence the term "mud volcano".
