ICB and BDY
Context
Iceberg cannot cross a bdy.
Proposal
This can easily be fixed for at least circumpolar configuration (icebergs are generated via calving and only exiting the domain) or improved for regional configuration (melt of icebergs calved outside the domain are represented via a climato).
- Add icb_del when an iceberg reaches a bdy => fix the issue in a circumpolar configuration (icb only exit the domain). Test in progress.
- Add capability to diagnose the melt by source sector => in order to build climato without some source sector for regional application) [ https://github.com/nicojourdain/NEMO_PARAMS_SIMU/tree/master/Merino_2017/MY_SRC ]
Full compatibility with bdy need to be investigate but probably much more complexe.
