The consortium will coordinate scientific input and develop plans for future marine hydrate expeditions to conduct research drilling, recovering samples of the formation, logging and analytical activities to assess the geologic occurrence, regional context, and characteristics of methane hydrate deposits along the continental margins of the United States, likely focusing on the Gulf of Mexico and the Atlantic margin.
