Summary
| Description | This dataset contains videographic data of ocean floor biology and geology at a suspected hydrocarbon seep sites in the Gulf of Mexico, captured during 149 submersible dives at 48 different lease block areas over the course of 15 dive seasons from 1988 to 2002, collected for studies funded by the Minerals Management Service, now Bureau of Ocean Energy Management (BOEM). Seep communities were found in all but four dives, although sparse community development was common. Because BOEM is tasked with protecting sensitive benthic communities from impacts of operational activities on the outer continental shelf and continental slope, locating these communities is an important task. Although use of surface attributes, particularly strength of seabed reflectivity (from 3-D seismic data) has been very successful in identifying areas of hard bottom (seep-related carbonate) and gas-filled sediment, visual evidence is still considered the best and most irrefutable data.
