Seismic and visual observation of seepage-related structures on the continental slope, Northern Gulf of Mexico
Two seismically similar structures have been the subject of submersible observations. The Green Canyon example is a conical mound 35 m of relief in water depths over 300 m. Eruptions of gas bubbles from the caldera-like crest create clouds of sediment into the water column which in turn settle along the flanks. This structure is clearly a mud volcano. The Mississippi Canyon example is an elliptical mound less than 20 m of relief and located in 700 m of water. Extensive benthic communities are observed along with broken and tilted blocks of authigenic carbonate. This structure is diapiric in nature.
