The system consits of the transducer, the electronic chassis, the computer 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. The angle between the ship centerline and transducer centerline is 45° direction starboard. |

| When starting the data acquisition the user set the PC time to UTC. Normally the difference between PC and UTC during the cruise is negligible.
GPS of Polarstern is used for the geographical position of the ADCP. |

| After the cruise, the operator transfers the measurement data along with required meta data to AWI after consultation 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://dship.awi.de/. |
