Abstract
As part of the BRAVOSEIS Antarctic project (CTM2016-77315-R), a multichannel marine seismic fieldwork was performed along the Bransfield Strait; namely in the corridor bounded by the Humpback and Orca submarine volcanoes. One of the objectives of this seismic exploration was to study in detail the active Orca volcano. For this purpose, we designed an inno- vative multichannel marine seismic acquisition consisting of scanning the study area with dense 2D profiles that combined reflection and refraction methods. We have called this methodology 2D-3D hybrid marine seismics (2D-3D HMS). In this contribution, we present the results of the first phase of the study, which focused on: (1) establishing a processing flow to remove multiples and increase the temporal-spatial resolution from all 2D seismic sections (Lin et al., 2019); and (2) To perform a preliminary interpretation of the resulting images in order to evaluate their information potential (Sun et al., 2019).
