1. ORGANISATION AND ARCHITECTURE 
OF THE COPERNICUS MARINE SERVICE 
1.1 Organisation 
Mercator Ocean International (MOi) set up an organisation 
to manage operations and regular evolutions of the 
Copernicus Marine Service (Figure 2) system, its main sub 
systems (TACs, MFCs, CIS, DU) and their interfaces. The 
organization also includes essential activities related to 
user service, user requirement gathering and analysis and 
user engagement (Delamarche et al., this issue; Giordan et 
al., this issue; Abadie et al., this issue).
