| Purpose | |
| Abstract | The SIMRAD EM 120 was used. It sends out 191 beams with a maximum opening angle of 140°. The mode was set to obtain equally spaced soundings on the sea floor. Yaw movements of the ship were compensated automatically by the software by transmitting the swath rather perpendicular to the track than to the ship’s axis. The opening angle was limited either by the maximum angle possible, a maximum angle set, or a maximum coverage in metre on the sea floor. Those values were adjusted to the special survey task depending on the requirements. |
