The Copernicus Marine Service is fed by the Copernicus 
Space component with Sentinel data, contributing and third- 
oarty missions and by in-situ observations from European 
and international networks, under the supervision of the 
Copernicus In-situ component; this flow of upstream data 
toward the service is expected to increase in the coming 
years thanks to the availlability of new Satellite missions and 
new iIn-situ platforms. MOi will maintain high-level 
coordination with ESA and Eumetsat to contribute to the 
definition of future Sentinels and to prepare their integration 
into the Service. Exchanges at European level with EEA (in- 
situ cross cutting coordination), EuroGOOS and EO00S, and at 
international level with GOOS, will be strengthened. Links with 
projects aiming at improving ocean observation systems will 
be kept and new links will be established.
