| The study of marine gas hydrates in great water depths using seismic data is limited by the resolution of current acquisition systems. The acquisition of very highresolution multichannel deep-towed seismic data aims to break this limitation. Deep-towed seismic system can provide seismic data with metric vertical resolution when the proper processing sequence is employed. However, the processing of deep-towed multichannel data is challenging as the source and receivers are constantly moving with respect to each other. In the first part of this PhD project, we developed processing methods tailored to the acquisition system SYstème SIsmique de Fond (SYSIF), developed by Ifremer. The processing sequence allows vertical and lateral resolutions up to 0.65 m and... |
