Gas hydrate on the crest of the Blake Ridge is concentrated over two depth zones: between 185 and 260 mbsf, and between 380 and 450 mbsf. Although the abundance of hydrate in the lower zone may be explained by methane cycling across the phase boundary between free gas bubbles and gas hydrate, the up...
