Note
titleAttention:

Please note that operations of the Multibeam Echo Sounder EM710 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 EM710 EM712 to AWI-Logistics in sufficient time prior to the cruise and clarify the data transfer after the cruise.

Summary

contenttypeSummary

Multibeam EM710 EM712 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° 140° and depth resolution 1cm. Data from the water column may also be stored.

Components
The EM710 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.
...
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).

Central geographical ship's position and time standard
The GPS position of the Trimble GPS receiver antenna is stored in the data files. The position is NOT centralized to the SES2000 transducers. Heave correction between the motion sensor and the transducer are calculated in the motion sensor and corrected values are transferred to the SES2000. Time synchronisation is achieved via NTP. Centralization of the GPS position to the transducer is achieved by  SIS software. GPS antenna position and transducer position related to the motion sensor position as a reference point are stored in the data files. Pay attention that in case of failure of the Trimble GPS sensor the Saab GPS sensor may be used as the reference GPS source. Please contact the bridge staff for information about the GPS receiver in use. Heave correction values are only available for the Trimble GPS receiver. Heave correction between the motion sensor and the transducer is calculated 
in the EM710 transceiver unit. UTC time synchronisation of the transceiver unit is achieved via GPS with PPS. The PC is synchronised with UTC via the Windows-Domain-Affiliation to ensure a correct naming of the data files.
