Integration of Coastal Observations and Forecasting
Networks
Is information from coastal stations used efficiently?
Put individual „pieces“ together.
Use modelling to optimise the integration.

Further perspectives
COSYNA (Coastal Observation System for Northern and Arctic Seas )
enable a future long term observational network for the North Sea and Arctic coastal waters
link to preoperational models for scientific and monitoring purposes
Goals: consolidate existing systems,
develop new ones,
detect environmental and climate changes in coastal areas,
produce forecasts,
provide products and knowledge.

However, at the present
• The existing systems are not harmonised. • Quality assessment is still a problem. • Real-time data transfer and exchange, as well
as availability to modellers is not well solved. • Assimilation of various sources of near coastal
data is still a complex scientific problem. • No enough coherence between physical,
chemical, geological and biological data.

Scientific background, state-of-the-art
• Focus: the North Sea, and in particular the area of German Bight and Wadden Sea
• already existing operational or near future operational systems and stations of GKSS and KDM partners
• COSYNA will deliver the spatial representation through a chain of reference points (RP) with long term observations
• mobile measuring techniques, such as autonomous underwater vehicles (AUVs, gliders) or ship surveys
• offshore wind turbines (WEAs) as platforms for RPs • (FerryBox) will be continued and extended regarding the number of
parameters
