Governmental agencies and research institutes are managing physical oceanography observation systems and take care of the first level of data processing for their own applications. An organisation collects, controls and distributes data in principle according to its own rules. However the development of Operational Oceanography at regional and global scales involves major investments which are difficult to be made by a single country. Active cooperation has thus always been a key issue for the development of the Global Ocean Observation System (GOOS).
is coordinating the development and operation of (European) regional operational systems (ROOSs) which encompasses five systems at present for the Arctic (Arctic ROOS), the Baltic (BOOS), the North West Shelf (NOOS), the Ireland-Biscay-Iberian area (IBI-ROOS) and the Mediterranean (MONGOOS) sea regions. These regional assemblies are instrumental for active cooperation in new developments, operations and planning investments. This is done via specific and thematic working groups that collect and express the best expertise on specific fields. Recent EU marine data infrastructures and EU Programs are widely based on EuroGOOS and ROOSs achievements.
The Copernicus Marine Environment Monitoring Service (CMEMS)
has been developed with support of the EU Copernicus programme and it uses information from both satellite and in situ observations to provide state-of-the-art analyses and daily forecasts for the marine environment. The In Situ Thematic Assembly Center (INSTAC)
is a component of CMEMS and it provides a research and operational framework to gather and deliver in situ observations and derived products based on such observations. For each EuroGOOS Region there is a Regional Data Assembly Centre (RDAC)
operated jointly with the CMEMS INSTAC and working closely with organisations operating monitoring stations. In this federative infrastructure, the quality of the products delivered to users must be equivalent wherever the data are processed: each RDAC is responsible for assembling data provided by operators of observing systems and bundling these into an integrated dataset for validation and distribution. The image below shows the INSTAC hierarchical architecture.
Routinely (e.g: every hour), each RDAC distributes all its new data on its regional portal. Files (i.e. NetCDF files) are organized in folders as described in the following image.
During the INSTAC operational activities, quality control is performed automatically on the data that is made available in real-time and near real-time, yearly scientific assessment performed on the latest 30 years of data ( 60 years for T&S and Global scale).
Note: A further validation and quality control as well as a more complete description with metadata take place when the observed data timeseries are passed to national data centres for long-term storage and stewardship. These data centres are mostly National Oceanographic Data Centres (NODCs)
and partners in the SeaDataNet
pan-European marine data management infrastructure which deals with data from a wide range of marine disciplines (geophysics, geology, chemistry, physics, and biology). SeaDataNet works closely together with EuroGOOS and CMEMS striving together for a complete coverage of available oceanography datasets. Together they are also the 3 pillars under the EMODnet Physics portal.
