Microbial Methane Generation and Gas Transport in Shallow Sediments of an Accretionary Complex , Southern Hydrate Ridge ( Odp Leg 204 ) , Offshore Oregon , Usa

Abstract

Sediments at the southern summit of Hydrate Ridge display two distinct modes of gas hydrate occurrence. The dominant mode is associated with active venting of gas exsolved from the accretionary prism and leads to high concentrations (15%–40% of pore space) of gas hydrate in seafloor or near-surface sediments at and around the topographic summit of southern… (More)
