Time synchronising of the computers is regulated via the affiliation to the Windows domain. Additionally, the NMEA-String ZDA is stored in the data files. The geographical ship's position is transferred to the Master PC together with the NMEA-String and to the data files. There is no centering of the GPS Position to the transducers. |

| 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). DShip data set can be extracted from https://dms.awi.de.||||
