Objective

The main objective of the Hydratech mission on the Norwegian margin was to provide a sedimentary image of part of the northern flank of the Storegga slide. The image obtained, in great part thanks to a high-definition 3D seismic survey, should highlight deformation within sediments, the various structures for escaping fluids, BSR distribution and possible links between these phenomena. The data will help understand the gas releasing mechanisms in play when gas hydrates are broken down in a continental slope subjected to heating and the related slope instability effects. In the framework of the European Hydratech project which aims to use geophysical methods to measure gas hydrates in sediments, these data will be combined with OBS measurements. They will supply a geometric model which the tomography and waveform inversion of OBS data will be based on. To supplement the high-resolution 3D seismic survey, 2D seismic profiles, Chirp sediment sounder profiles and a bathymetric survey were made. They should enable the 3D box observations to be replaced in the regional context.
