| Purpose | Upper slope gas hydrate dynamics on disparate part of the margin (with and without seeps; with and without long erosional history) | ||||||||
| Location | Atlantic margin between Alvin Canyon and Cape Hatteras | ||||||||
| Summary | Piston cores, multicores, real-time video on multicores, EK60 data, Chirp 424 data, CTDs | ||||||||
| Info derived | heat flow data; water column CH4 concentrations; subbottom imaging; pore water organic & inorganic chemistry, gas composition and carbon isotopes | ||||||||
| Comments | > PISTON CORING CRUISE (using PCMSC gear) > Heat flow instrumentation will be provided by NSF facility at UCSC > Edgetech 512 needed > CTD will be provided and staffed by U Delaware | ||||||||
