Model-Based Identification of the Base of the Gas Hydrate Stability Zone in Multichannel Reflection Seismic Data, Offshore Costa Rica

Figure 9

(a) The clear BSR (blue thick line) and predicted BSR (red line) are plotted into the depth-migrated section of line BGR99-46. (b) The turquoise lines are former BSR interpretations for which heat flow values were calculated. The left-most turquoise reflection can be disqualified as a BSR because it exceeds heat flow boundaries and contradicts its trend. The heat flow in the middle belongs to the actual BSR identified in the far offset CMP stacks. The reflection marked turquoise on the right belongs to a sediment unconformity.
