COSYNA (Coastal Observation System for Northern and Arctic Seas) is an operational coastal monitoring, forecasting and information system for the North Sea composed by fixed platforms, FerryBoxes, gliders and HF-radar systems. It is being developed by institutes of the German Marine Research Consortium (KDM) and collaborating institutions and is operated by the HZG Research Centre. The infrastructure represents an investment of 9 M €. It was build up since 2007 and is fully operational since 2012.

AWIPEV_UNS is designed as an experimental platform project between the HZG and the AWI to host sensors and sensor units in a polar fjord system. The system provides underwater data connection and power as well as a server infrastructure for system and sensor control. Attached is an upward looking ADCP and a CTD plus sensors for turbidity, oxygen, chl-a fluorescence.

  • Partially remote: the presence of the user group is required at some stage e.g. installing and un-installing user’s equipment.

Unit of access (UA): 14 days.

Quantity of access available to JERICO NEXT users: 2 UA=2 periods of 14 days each. Users can apply for a minimum access duration of 14 days (1 UA) or for the maximum duration of 28 days (2 UA). Access duration corresponds to the period of installing, operating and un-installing a measuring system by the users.

The system is additionally equipped with a FerryBox system retrieving the same parameters from a fixed inlet at 11 m water depth.

The applicant can attach his/her own sensor either in the FerryBox, in situ to the base station of the under water part of the observatory or to the underwater profiling unit. The user will have full access at all three sensor carriers.

Installation will be supported by a team of technicians and scientists of AWI/HZG for preparing the instrumentation; service the instrumented node, support diving for installation and recovering of the sensors at the end and process the data. A “virtual computer” is also provided to the user for full access to the instruments installed underwater.

Data storage for own sensors is only temporally restricted. The owner of a sensor has to ensure, that the data are well stored.
