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.

0Rawdata
Mass data: The data acquisition and processing software VmDas creates rawdata on the local drive of the computer.
Every hourday the software Easy2Sync copies the data to a local backup file structure. 
Every 3 hours the software Easy2Sync synchronizes the backup data to the directory structure of the mass storage. 
Attention: Deleting files in the directory structure of the mass storage will also delete these files in the backup file structure with the next synchronization run. But: As long as these files are not removed from the local rawdata drive these files will be copied again to the local backup file structure with the next backup run and to the directory structure of the mass storage with the next synchronization run.

After the cruise, the operator transfers the measurement data along with required meta data to AWI after consultaionconsultation 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/.
