Please note that operations of the Multibeam Echo Sounder Hydrosweep DS3 EM712 requires experienced scientific staff on board and can be only operated upon request. The system is not operated by the ship's crew. Request operations with the Multibeam Echo Sounder Hydrosweep DS3 to AWI-Bathymetry and EM712 to AWI-Logistics in sufficient time prior to the cruise and clarify the data transfer after the cruise. |

The
...
EM712 consists
...
of a transducer array for transmitting (Tx) and an array for receiving (Rx), the transceiver unit, the data aquisition PC with the aquisition software SIS and two processing PCs (bridge and Messraum) with the software Caris HIPS/SIPS.
The software "Seafloor Information System" (SIS) contains several graphic displays for quality checks and for system calibration as well as other tools. SIS supports an online/realtime data cleansing. Both SIS and the processing software Caris HIPS/SIPS are protected via a dongle. Please contact the bridge staff for suppport.
Sound velocity can alternatively been received from two sensors: from Sound Velocity Probe (Valeport Mini SVS) or calculated velocities from sensor Thermosalinograph.
Ships position is received from GPS Receiver Trimble Marine SPS461 . Ships orientation is received from Motion Sensor (PHINS).

|
After the cruise, the operator transfers the measurement data along with required meta data to AWI after consultaion with the data scientist and AWI Logistics. Then, the data including meta data can be extracted from https://www.pangaea.de/ (for authorized users only). The reduced DShip data set can be extracted from https://dms.awi.de. |
