=Coarsening of physics for biogeochemistery model=

A capacity of coarsening physics to force a BGC model coupled to NEMO has been developped in NEMO_3.6. 
This capacity is not included in the [https://forge.ipsl.jussieu.fr/nemo/browser/branches/2015/nemo_v3_6_STABLE/NEMOGCM NEMO_3.6] , but is available in a specific [
https://forge.ipsl.jussieu.fr/nemo/browser/branches/2015/dev_r5003_MERCATOR6_CRS branch] of the 3.6 stable. This branch is regularly phazed with the NEMO_3.6.
