Attention:
Please note that operations of the Multibeam Echo Sounder EM710 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 EM710 to AWI-Logistics in sufficient time prior to the cruise and clarify the data transfer after the cruise.
Summary
Multibeam EM710 is a high-resolution seafloor mapping system. It is suitable for water depths up to 2000m depending on the configuration of the transducers. Maximum ping rate is 30Hz and maximum fan width 140° and depth resolution 1cm. Data from the water column may also be stored.

Components
The EM710 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).
