Abstract
Natural gas hydrate was first recognized on the Cascadia margin in 1985 through the characteristic bottom-simulating reflector (BSR) on conventional multichannel seismic data (Davis and Hyndman, 1989, Davis et al., 1990). Since then, the Cascadia accretionary margin has received the most intensive studies of any convergent margin for determination of the in-situ properties of marine gas hydrate. Key control for understanding the properties and formation processes of hydrate has been derived from drill holes of the Ocean Drilling Program (ODP) Leg 146, carried out in 1992. Estimates of hydrate concentration were provided through analysis of downhole seismic and resistivity logs and through measurement of chlorinity in pore fluids from recovered sediment core samples.
