The system consits of the transducer, the electronic chassis, the computer in the echosounder room (G-707) and the subsidiary display at the winch control station (User).
The data acquisition and processing software VmDas and the synchronizing software Easy2Sync are installed on the computer.
The 150kHz transducer is mounted behind an ice protection window and reaches water depth up to 350m with resolution of 4m ("Cell Size" at 1 to 5 kn ship's speed) and accuracy of about 0.30 m/s for a Single-Ping measurement.
The angle between the ship centerline and transducer centerline is 45° direction starboard.

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, unevaluated DShip data set can be extracted from https://dmsdship.awi.de/.
