The Blake Ridge is one of the best-studied methane hydrate systems on Earth. Here a fine-grained sediment drift deposit hosts a significant quantity of methane hydrate and methane gas. In this data volume, a clear bottom-simulating reflection (BSR) marks the hydrate/gas phase boundary, and numerous bright spots beneath the BSR indicate a thick, complex free gas zone. In addition, this volume displays the interactions between the hydrate/gas system and the compaction normal faulting and sediment waves that characterize the sediments.
This data was acquired using a single, 4-km-long streamer, with streamer feathering used to fill in the 3D bins. The source was a small array of two 105/105 cu. in. GI guns.
