Position

Data logging, storage and archiving

Logged parameters


Central geographical ship's position and time standard

Time synchronising via Polarstern Network.
Geographical ship's position via Polarstern Network.

Rawdata storage on board

Raw data is temporarily stored to the data acquisition unit and written on tapes on a regular basis.

Dship

No data transfer to DShip.

Data archiving on land

After the cruise, the operator transfers the raw 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) for further processing.
