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

Figure 1

The reflection seismic profiles (light grey lines) offshore western Costa Rica were acquired during cruises BGR99 and SO81. The crosses mark the drill sites of ODP Leg 170 north-west of the Paleo Plate Boundary (PPB). The PPB refers to the boundary of the Cocos Plate’s two distinct origins, the East Pacific Rise, and the Cocos Nasca spreading centre. The Ridge Jump is characterized by a seamount chain [32]. The thick black line is profile BGR99-46, which is discussed in this work and is located offshore Nicoya Peninsula. The figure is modified from Müller et al. [13] who interpreted the BSR occurrence (dark grey shaded area) along the continental margin from onboard processed data.
