THE CONSEQUENCES OF METHANE OXIDATION AT THE SULFATE-METHANE INTERFACE IN A METHANE-RICH CORE FROM THE NORTHERN GULF OF MEXICO

A unique opportunity to sample across the sulfate-methane interface (SMI) in a gas-rich continental margin sediment core from the Gulf of Mexico was provided by the giant gravity coring capability of the ship R/V Marion Dufresne. This core (MD02-2571) has revealed a detailed record of the biogeochemical changes that occur across this boundary. Porewater sulfate concentrations are nearly depleted by 300 centimeters below the seafloor (cmbsf) and methane concentrations rise sharply below 300 cmbsf simultaneously with formation of a bubble-textured sediment.
