Attention:
Please note that the Ferrybox can only be operated upon request. Request operations with the Ferrybox to AWI-Logistics in sufficient time prior to the cruise.
Ferrybox data stored in data acquisition system DShip are uncorrected measurement data.

Rawdata storage on board
Alle Messdaten werden im DShip-System abgespeichert.
Ferrybox data stored in data acquisition system DShip are uncorrected measurement data.
The data acquisition and processing software VmDas creates rawdata on the local drive of the computer.
Every hour 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.

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, unevaluated DShip data set can be extracted from https://dms.awi.de.
Kurz nach Ende eines Reiseabschnittes stehen die Messdaten der Ferrybox im DShip-Landsystem zur Verfügung.
