Alternate Leg: ID (PE-04-49; P1-04-GM) Area of Operations : Atwater Valley, Mississippi Canyon, Gulf of Mexico, North America, North Atlantic Dates: June 20, 2004 to June 23, 2004 Chief scientist: Debbie Hutchinson
Rob Evans - WHOI Objectives: Collect bottom camera and electrical resistivity data across two possible gas hydrate mounds in the Mississippi Canyon, northern Gulf of Mexico, as part of a site survey for the JIP/DOE Gas Hydrates Drilling Program. Type of Activity: Bottom Photography
Bottom resistivity profiling (WHOI) Information to be derived: Sea floor map
bottom imagery to investigate benthic distribution and gas hydrate
electrical resistivity profiles across mounds and at drilling transects Summary: This was a successful cruise with 5973 bottom images collected on four tows; the EM data fulfilled the objective of showing proof of concept for the system (17 km on 9 lines).
