SEPTEMBER 2021 
The overall development is supported by the OSR chair 
through regular remote calls, and individual exchanges. 
Fach cycle for the draft development spans nearly one 
year, and is organized within several milestones (MS). 
These include: 
MS1 - Establishment of call of contribution guideline‘ 
The OSR chair develops each year in October 
November a guideline for the call of contribution, 
which includes amongst others the criteria for 
contributions for each OSR chapter, 
MS2 - OSR call of contribution: The call of contribution 
-uns each year from December to January (year+1) 
which usually ends during the last week of January,

period is organized within several steps in support of 
the author teams, 
-MS5 - OSR first submission to the Journal for peer- 
review in July, 
MS6 - OSR peer review process In collaboration with 
the Journal of Operational Oceanography. 
Albeit the huge challenges faced with a regular 
“eporting process passing peer-review such as the 
Zopernicus Marine Service Ocean State Report, or the 
3ulletin of the American meteorological Society (BAMS) 
statement of the climate (e.g., Blunden et al., 2020), the 
science community and the community working at the 
science-policy interface have strongly recognized these 
efforts. One particular reason is that due to the peer 
review, this regular reporting can be accomplished in, 
for example, assessment processes, which act at the 
science policy-interface (e.g., IPCC).
