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

Figure 8

(a) The clear BSR (blue lines) is regularly distributed along the profile. After calculating its corresponding geothermal gradient and interpolating it, a modeled BSR (red lines) is derived. (b) The resulting smoothed heat flow trends with error bounds and an analytical heat flow curve from Molnar and England [51] are compared to in-situ data (Figure 3). The values north of the Paleo Plate Boundary near ODP Leg 170 and south of the plate boundary (S6) were derived from Langseth and Silver [18] and the values south of the plate boundary M54-43 and M54-113 were acquired by Grevemeyer et al. [16].
