3. THE COPERNICUS MARINE SERVICE
OCEAN REPORTING SUMMARY
FOR POLICY MAKERS
Each year, a summary for policy makers of the OSR (cycle
— 1) is coordinated by the OSR chair, and relies on a co-
construction approach with scientists, communication and
graphic designers. These documents are freely available
on the Copernicus Marine Service portal. The launch of
this work runs in parallel with the draft development of
*he new upcoming OSR cycle (Figure 2). The 0SR summary
organisation is shown In the lower part of Figure 2, and
includes the following steps:
- during Q1 of the OSR cycle-1 year (February to March),
the storyline of the OSR summary is developed in
collaboration with Mercator Ocean international and
a team of communication experts,
the O0SR summary storyboard is then revised and
refined by a science writer and concept expert from
an external company collaborating with the OSR
chair, and the internal communication expert during

March-April. This review is organized through a large
set of co-working sessions during remote calls,
once the storyboard is drafted, a science writing
expert reworks the text, and is then revised by the OSR
chair and the internal communication expert through
several remote exchanges, and co-working sessions
(April-May). Occasionally, few additional experts are
solicited for a point-wise review of the text to assure
that the science content is appropriate,
in parallel, co-working sessions are organised for

the final phase takes place during end of May to early
June to prepare the final draft of the OSR summary
document, which is usually anticipated for publication
in early June.

and institutions to the wider public. The topical content
