In situ benthic fluxes from an intermittently active mud volcano at the Costa Rica convergent margin [PDF]

, 2005
Along the erosive convergent margin off Costa Rica a large number of mound-shaped structures exist built by mud diapirism or mud volcanism. One of these, Mound 12, an intermittently active mud volcano, currently emits large amounts of aqueous dissolved ...
