The physical understanding of the vertical upwelling velocity and bottom boundary layer dispersal of a hydrocarbon seep in the Gulf of Mexico is extremely limited due to paucity of direct long-term measurements and to the time variability of the bubble plumes and boundary layer dynamics. We aim to 1) measure the vertical upwelling velocity of a natural hydrocarbon seep at GC600 or GC185 and its role in vertical transport of methane and oil to the surface and 2) investigate the turbulent bottom boundary layer dynamics that causes horizontal and vertical dispersal, including resuspension of hydrocarbon-containing deposits. The new measurements collected in the context of the proposed project provide a useful complement to the measurements taken during ECOGIG-2.
