In this work, we present some new procedures, aimed to solve some problems bound to the particular acquisition geometry, when OBSs are used. The tomographic datuming enables the reduction of the travel path within the water layer, while the irregular gridding, applied to theinterfaces, enables a more reliable and efficient representation of the geometry of the layers.The method is applied to the 3D OBS data set acquired offshore Svalbard, within theHydratech European project, aimed to study of the presence of gas-hydrates within the sediments.

Abstract
In this work, we present some new procedures, aimed to solve some problems bound to the particular acquisition geometry, when OBSs are used. The tomographic datuming enables the reduction of the travel path within the water layer, while the irregular gridding, applied to theinterfaces, enables a more reliable and efficient representation of the geometry of the layers.The method is applied to the 3D OBS data set acquired offshore Svalbard, within theHydratech European project, aimed to study of the presence of gas-hydrates within the sediments.File in questo prodotto:
