    Science objectives/activities planned:
The proposed program is a multi-disciplinary, multi-project expedition to study deep sea resources off the U.S. eastern seaboard, from New England to Georgia. Deep coral beds in the vicinity of Veatch Canyon are critical fish habitat targeted by deep trawlers. Soft corals are long-lived and susceptible to permanent damage by trawling.
Methane hydrates are ice with hydrocarbon gases locked inside. They exist on most of the world's continental margins. Recently, they have been implicated as a major cause of slope failure and climate variability. In and near Hudson Canyon, gas bubbles have been detected and mass slumping is apparent. Research will attempt to determine if buried hydrate beds are the cause of both.
The Blake Ridge is the first site in the Atlantic where cold seep chemosynthetic communities have been observed-- mussel beds found during ODP drilling surveys. We will explore the beds and study the microbiology and geochemistry of the Blake Ridge, in the vicinity of ODP leg 164 boreholes that found extensive hydrates.
