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. COSYNA_SFB is a Stationary FerryBox system, including self-cleaning features, installed in a container at the mouth of the Elbe River equipped with sensors T, C/S, turbidity, DO, pH, chlorophyll-afluorescence, CDOM fluorescence, nutrients (NOx, NO2, PO4, SiO2) and a cooled water sampler.

COSYNA_UNH is a cabled underwater observatory operated by AWI together with HZG since 2012 and is providing power, network connection and server support for the permanent operation of in situ sensor systems. The node system has 10 underwater pluggable access points (for network (100 Mbit/ 1Gbit) and power (48V / 2.5 Amp) and is equipped with a standard sensor carrier with an ADCP) and a CTD plus Chl-a fluorescence, oxygen and turbidity sensors for basic oceanographic measurements. The 10 access points are fully remotely controlled. The user gets a “virtual computer” on the COSYNA server on which she/he can log in via remote access software and install own programs to control her/his sensor.

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.

COSYNA provides near real-time data from integrated observations and model results. The observations comprise a variety of in situ techniques (e.g. FerryBox, Gliders, Cabled Underwater Observatories) as well as remote sensing from shore by radar and from space by satellite. Key physical, sedimentary, geochemical and biological parameters are observed at high temporal resolution in the water column and the upper and lower boundary layers. COSYNA’s modelling part consists of nested models with different grid sizes for hydrography (salinity, waves, currents), for suspended matter and for biogeochemical and ecosystem processes. Sophisticated data assimilation procedures, i.e. continuous corrections of the models by observations, improve the reliability of now-casts and short-term forecasts. All data and plots are generally available for download through the data portal (http://codm.hzg.de/codm/). FerryBox data can be directly accessed via the data portal ferrydata.hzg.de where different vizualizaton tools are available (e.g. single transect, pool data along a certain transect for a longer time period or time-series at certain locations). Furthermore, all datasets can be exported in ASCII (tab separated tables) or NetCDF format and downloaded. COSYNA’s motivation is bridging the gap between operational oceanography and the various users of forecasts of the marine state. For further outreach to stakeholders and the wider community an app has been developed for the most common platforms.
