Based on requests from colleagues which were present at the recent Baltic Earth Workshop on "Coupled atmosphere-ocean modeling for the Baltic Sea and North Sea" (http://www.baltic.earth/caom2017), we have prepared a forum platform for discussing related subjects. You are welcome to have a look and participate in the discussion on this new forum, and please also spread this information among your colleagues. You just need to register, then you will be able to post messages and open new topics. For a start we have two forums open: "General issues" and "Nemo". More can be added upon request. If you encounter any problems in using the forums let us know as we are just starting this.
