EFFECT OF CHANGES IN SEAFLOOR TEMPERATURE AND SEA-LEVEL ON GAS HYDRATE STABILITY
We have developed a one-dimensional numerical computer model (simulator) to describe methane hydrate formation, decomposition, reformation, and distribution with depth below the seafloor in the marine environment. The simulator was used to model hydrate distributions at Blake Ridge (Site 997) and Hy...
