Figure F14. A. Seismic velocity image obtained from wide-angle ocean-bottom seismometer (OBS) data. OBSs are deployed every 5 km along Line IBr5. B. Depth-converted multichannel seismic (MCS) reflection profile along Line IBr5. Yellow lines = iso-velocity contours of 5 and 6 km/s obtained from the seismic velocity image in A, which are interpreted as the depth to igneous basement (upper crust) and middle crust, respectively. C. Lithologic interpretation of the seismic image.
