New URL for NEMO forge!   http://forge.nemo-ocean.eu

Since March 2022 along with NEMO 4.2 release, the code development moved to a self-hosted GitLab.
This present forge is now archived and remained online for history.

New code to reduce Stokes drift and allow ice sheltering

ln_zdfosm_ice_shelter if true=> ice sheltering
rn_zdfosm_adjust_sd sets factor to reduce SD by if not using new van Roekel method
nn_osm_SD_reduce if 0 => use rn_zdfosm_adjust_sd

if 1 => reduce SD to hbl/10 average
if 2 => ewduce SD to matched exp @ hbl/10
