The ferrybox system consits of different installed sensors, a pump control system and data aquisition and storage unit. Installed sensors: pH (Glas Elektrode EGA 140-X-E, Meinsberger MV3010pH Messverstärker), O2 (Oxygen Optode 3835, Aanderaa), Phycocyanin (Cyclops (1) P, Turner), CDOM (CDOM Cyclops (2) U , Turner), salinometer (FSI), chlorophyll a and turbidity (Scufa, Turner) Control system: flow-through •sensor Durchflusssensor: (Flow Main, Flow Out • Drucksensor • Ventile: Motorkugelhahn Einlass Coster, Motorkugelhahn Ausgang Coster • Magnetventile: Süßwasser normal, Süßwasser Druckspüllung • Säurepumpen: 1. ProMinent Säurepumpe für H2SO4, 2. ProMinent Säurepumpe für Oxalsäure • Kreiselpumpe: Mainpump |

AlleFerrybox Messdatenraw werdendata im DShip-System abgespeichert. Ferrybox data(uncorrected measurement data) are 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. |

AfterShortly after the cruise, the operatoruncorrected transfers theferrybox measurement data alongare 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. Ferrybox data stored in data acquisition system DShip are uncorrected measurement dataavailable at the DShip onshore system. |
