Time synchronising of the computers is regulated via Polarstern GPS.
Geographical ship's position via HYDRINS centering to HYDRINS offset correction in AHC. 
 Rawdata storage on board 
Mass data: The data acquisition and processing software creates rawdata to the directory structure of the mass storage. A reduced data set is also stored in DShip sytem.

Data archiving on land 
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 DShip data set can be extracted from https://dms.awi.de.
