| Abstract | During the SO 177 cruise, the Simrad EM 120 Multibeam echosoundeur, available on R/V SONNE since June 2001, was used continuously. During DeepTow profiling dense line offset was used to reduce the opening angles of the beams in order to receive higher resolution images while still covering the complete area. At the beginning of the cruise a water velocity profile was measured to a depth of 2000 m, at the entrance to the beginning of the Formosa Canyon. |
