-A capacity of coarsening physics to force a BGC model coupled to NEMO has been developed in NEMO_3.6. This capacity allow to run 'online' a BGC model coupled to OPA-LIM with a lower resolution, to reduce the CPU coast of the BGC model, while preserving the effective resolution of the dynamics.
+A capacity of coarsening physics to force a BGC model coupled to NEMO has been developed in NEMO_3.6, in an associated branch. This capacity allow to run 'online' a BGC model coupled to OPA-LIM with a lower resolution, to reduce the CPU coast of the BGC model, while preserving the effective resolution of the dynamics.
 
-This capacity is not included in the [browser:branches/2015/nemo_v3_6_STABLE/NEMOGCM NEMO_3.6] , but is available in a specific [browser:branches/2015/dev_r5003_MERCATOR6_CRS branch] of the 3.6 stable. This branch is regularly phased with the NEMO_3.6.

 An associated ticket to follow evolution is  [ticket:1426 here].
 
 A presentation is available [attachment:crs_wiki_1.1.pdf​ here], where the methodology is presented.

+For the future, a few options are on the table to implement coarsening for biogeochemistry in 4.0 and future releases. Those will be discussed in Autumn 2018
