Methane gas hydrate is a type of solid crystalline mineral structured as a clathrate that exists at low temperatures and high pressures. Typically composed of methane and water, hydrates inhabit stratal pore space and fractures in the subsurface (Bryan, 1974). Hydrates are encountered in marine continental margin environments worldwide and although estimates vary widely, a recent estimate of methane carbon stored within gas hydrates is thought to be 455 Gt (Wallmann et al., 2012). Mapping bottom simulating reflections (BSRs) in two-dimensional (2D) reflection seismic data is one method for deriving first-order approximations of global amounts of methane stored in hydrate in the marine environment (e.g. Kvenvolden, 1988;Milkov et al., 2003).Within seismic data, (BSRs) are common geophysical identifiers of the approximate base of the gas hydrate stability zone (BGHSZ), and as such are commonly used as indirect indicators of hydrate (e.g.
