Abstract :
IFREMER has recently developed a deep-towed seismic system designed for High to Very High resolution near-bottom marine seismic surveys.This paper presents this new tool which is dedicated to the study of deepwater geological objects especially geohazards. After a technical description of the system, we expound an overview of the complete workflow from survey design to amplitude preserved processing illustrated by data acquired during the first operational cruise.
