Substantial volumes of methane gas are trapped below the seafloor and in permafrost by an
ice-like solid called clathrate hydrate. Global estimates of the methane in clathrate hydrate …

The North Andean convergent margin is a region of intense crustal deformation, with six
great subduction earthquakes Mw≥ 7.8 this century. The regional pattern of seismicity and …

Using a new analytical formulation, we solve the coupled momentum, mass, and energy
equations that govern the evolution and accumulation of methane gas hydrate in marine …

Seismic velocities measured in three drill holes through a gas hydrate deposit on the Blake
Ridge, offshore South Carolina, indicate that substantial free gas exists to at least 250 …

We test a hypothesis relating large pore water sulfate gradients to upward methane flux and
the presence of underlying methane gas hydrate on continental rises by examining:(1) pore …

A thermodynamic model for hydrate formation is used to compute the solubility of methane in
pore water in equilibrium with gaseous methane or methane hydrate or both. Free energy of …

The geologic setting of the formerly glaciated mid-Norwegian continental margin exerts
specific controls on the formation of a bottom-simulating reflector (BSR) and the inferred …

Marine seismic data and well-log measurements at the Blake Ridge offshore South Carolina
show that prominent seismic bottom-simulating reflectors (BSRs) are caused by sediment …

Remote seismic methods, which measure the compressional wave (P wave) velocity (Vp)
and shear wave (S wave) velocity (Vs), can be used to assess the distribution and …

We obtain the wave velocities of ice-and gas hydrate–bearing sediments as a function of
concentration and temperature. Unlike previous theories based on simple slowness and/or …
