3. IN-SITU UPSTREAM COORDINATION 
AND REQUIREMENTS 
Juality assurance, standardization) for physical, chemistry 
and biological in-situ data and avold duplication of work 
and developments. Figure 4 gives an overview of the in- 
situ coordination activities carried out for the Copernicus 
Marine Service. 
Operational aspects of the Service’s in-situ component are 
implemented by the INS-TAC which is responsible for the 
Implementation of technical interfaces with upstream data 
providers, and day to day operations. 
Copernicus Marine Service requirements for the in-situ 
observing system have been previously gathered in the 
framework of the GISC (Global Monitoring for the 
Environmentand Security/Copernicus In-Situ Coordination) 
project led by the European Environmental Agency. As the 
Zopernicus Marine Service evolves, some of these 
-equirements have been met, while others need to be 
updated to the new commitments and capabilities of the 
service. As for Satellite observations, new In-situ needs 
‚regularly gathered by MOi and the Service's partners) 
must go through the added-value chain of the service to be 
translated into observation requirements. The latter are 
then presented and discussed with the main European 
institution dealing with in-situ data coordination, such as 
EEA, EuroGO00S, Euro-Argo, to plan their Implementation 
The Copernicus in-situ component is organized and 
implemented by member states. The European Commission 
delegated to the European Environment Agency (EEA) and 
the Entrusted Entity (Mercator Ocean International) the 
high-level coordination aspects, and political agreements 
at member state and EU levels. 
A long-standing partnership with EuroGOOS (an association 
of national governmental agencies and organizations that 
form the UNESCO-IO0C GO0S Regional Alliance for Europe) 
has been established for definition of in-situ requirements 
and the identification of potential improvements for in-situ 
observing systems relevant to the Service. 
At European level, MOi contributes to the development of 
the European Ocean Observing System (EO0S) a framework 
to better coordinate Europe’s ocean observing capacity, 
and collaborates with DG MARE EMODnet initiative to 
improve data assemblv tasks (ingestion of new data sets,
