INTRODUCTIOP® 
In 2015, Mercator Ocean International (MOi) and the 
Copernicus Marine Service (CMEMS) launched the ocean 
reporting activity, which consists of three principal tools: 
the peer-reviewed annual Ocean State Report (0SR), 
the Ocean Monitoring Indicator (OMI), 
the annual summary for policy makers based on 
information from the OSR and OMls. 
The Copernicus Marine Service ocean reporting activity 
contributes to European and International agencies or 
organizations in charge of environmental and climate 
monitoring, policy and decision-makers. Its additional aim 
is to increase general public awareness about the status of, 
and changes in, the marine environment (von Schuckmann 
et al., 2016). 
Section 2 provides insight into the Copernicus Marine 
Service OSR functioning and major outcomes, Section 3 
focusses on the Service OMI framework and Section 4 
describes the Service summary for policy makers. Section 5 
displays an outlook on future plans for the Copernicus 
Marine Service ocean monitoring activity during the second 
phase of Copernicus Marine Service.
