Distribution of the gas hydrate stability zone in the Ross Sea, Antarctica

ABSTRACT The theoretical gas hydrates stability zone (GHSZ) in the Ross Sea area was evaluated by mean of a steady state simple approach by using bathymetric data, sea bottom temperature, a variable geothermal gradient and assuming that the natural gas is methane. The results from our study suggest...
