COSYNA aims to significantly advance the scientific understanding of hydrodynamic processes, improve operational models, provide products for various interest groups, and support technological development, e.g. for automated, quality controlled routine measurements or for error and data analysis. A major challenge is a system-wide integration to build a coherent platform for sharing or retrieving data, products, and infrastructure. COSYNA provides research infrastructure enabling research on a wide range of temporal and spatial scales, from extreme events to long-term trends, from small scale turbulence to North Sea-wide processes and applied to coastal areas worldwide.start
* Which key regions have the largest influence on coastal seas and what is the ideal instrumentation and strategy to observe them? * How can the large range of relevant spatial and temporal scales ranging from minutes to decades and from meters to hundreds of kilometers be captured simultaneously? * How can an observing system be optimized to provide relevant and high-quality information in a cost effective way? * How can an observing system be constructed in a modular way to be used for a variety of processes, scales and scientific questions? * How can observing systems become “intelligent”, i.e. sensors communicate with each other and use this information to create their own measurement strategies? * How are observational gaps filled and model uncertainties reduced by new methods of merging observational data with dynamic models and statistical methods (data assimilation)? * How can the data be made publically available in an easily accessible and comprehensive way?start

Since COSYNA is one of the densest observing systems located in one of the most heavily used coastal areas in the world, it may serve as a role model for other parts of the “Global Coast“. Many global problems such as climate change, sea level rise, or ocean acidification influence in particular the ecosystems and communities along the coasts. The impact of these problems as well as the choice of the tools for their management, however, varies strongly with region.start
