COSYNA stands for 'Coastal Observing System for Northern and Arctic Seas'. The principal goal of the COSYNA-Project is the construction of a long-term observatory for the German part of the NorthSea. The main task of the COSYNA data management is the integration of different data sources in order to provide a web based visualisation and access to observational as well as forecast data. The usage of standards like OGC standards or community standards like NetCDF, OPeNDAP or ncWMS is essential for the data management in COSYNA. The data are stored in an Oracle database for time series-like data and as NetCDF files for data which are acquired simultaneously at different locations. The time series-like data can be freely accessed using OGC SOS (Sensor Observation Service) whereas NetCDF files are available via OPeNDAP. This concept of Open Data within COSYNA is planned for near real time data without quality control.
