The Copernicus Marine Service must deliver and 
Mmaintain a competitive, state-of-the-art and operational 
European service responding to all users. It is monitored 
through key performance indicators (KPls), quarterly and 
annually reported. Such KPls assess its reliability against 
operational commitments, service level agreement 
;timeliness, robustness, etc.). The service monitoring 
activity encompasses many KPls to steer the service 
and its uptake, and for example provides with figures 
about the product portfolio evolution, the evolution of the 
ıumber of subsceribers and their detailed characteristics, 
and the monitoring of the service availability and product 
timeliness. 
The Copernicus Marine Service also needs to maintain 
a permanent dialogue with users while collecting their 
-equirements and supporting them in the use of the service 
chrough user support and training services (Giordan et al., 
this issue). 
The present paper showcases elements of the Service 
monitoring and user requirement activities, and provides 
pbrospects for the next 2021-2027 Copernicus phase

1. PRODUCT AND SERVICE MONITORING 
The service monitoring activity encompasses many KPls 
to steer the service, its portfolio, its operationality and its 
uptake. For example, it provides with figures about the 
product portfolio evolution, the evolution of the number 
of subscribers and their detailed characteristics, and the 
monitoring of the service availability and product timeliness. 
1.1. Product Management 
Since 2015, Mercator Ocean international (MOi) has managed 
system and service evolution through a formal development 
process (specification, design, acceptance, entry into service) 
with a review process at the end of each development phase. 
This has led to regular catalogue releases: 25 catalogue 
releases took place from 2015 to 2021. 
Between 2015-2020, the catalogue has been enlarged from 134 
to 180 ocean products (Figure 1, left panel), and the number of 
active users downloading these ocean products every year has 
also been increasing (from 2 000 to 9 000 active users from 
2015 to 2020 respectively) (Figure 1, right panel):
