Purpose | |
Abstract | SO175 aimed for a multidisciplinerary geoscientific approach with an international group of researchers. Methods covered the entire span from geophysical data acquisition, sediment coring at sites of active fluid venting, in situ heat flow measurements across the entire length of the Gibraltar thrust wedge, the deformation front, landslide bodies, and mud volcanoes, and finally the deployment of a long-term pore pressure probe. The EM120 was used continuously during SO175. Depending on the state of the sea, an opening angle of 60-70° was used, restricting the coverage to a max. 14 km wide swath to gain a more continuous spacing of beams on the ocean floor. The spacing within this limits was controlled automatically by the echosounder system. |
