iSIMM pushes frontiers of marine seismic acquisition OBS

Abstract

Last summer (2002) the iSIMM (integrated Seismic Imaging and Modelling of Margins) project successfully completed a seismic programme on the northwest European Atlantic margin with OBS acquisition by the NERC vessel Discovery and Q-Marine acquisition by WesternGeco’s Geco Topaz. This project is pushing the frontiers of technology in seismic acquisition targeted at subbasalt and deep crustal imaging. These data will constrain new theoretical models which address the development of rifted continental margins, including the effects of dynamic support by mantle plumes and the production and intrusion of igneous melt.
