     # Based on LIM3_29 one BUT:[[BR]]

     >>>> '''nn_ico_cpl''' = 0 & '''nn_fsbc''' = 5 & increase iteration number for the rheology nevp=600 instead of 300[[BR]]
     '''Results:'''  stops when reaching 10th year in March in the North Canadian archipelago in the sea-ice accumlulation [[BR]]
     area ixj=66,146 i.e. always in the same area for LIM 3.0

     >>>> relaunch from scratch with nevp=900[[BR]] 
     '''Results:''' idem as above resulting with no changes in results [[BR]]

     >>>> new attempt with coupling frequency ocean/sea-ice '''nn_fsbc''' set to 3 instead 5 and with '''nn_ico_cpl''' = 1 [[BR]]
     i.e. computation of the wind stress each time step but with a wind module computed each nn_fsbc only [[BR]]
     '''Results:''' stops after just 9 years run with a negative salinity in the Canadian North[[BR]]

     # Updated with the revision number r1170 as for the CLIO_LIM2 configuration:[BR]]

     - last modification concerning sbcfwb.F90 with the sign of the term empold which must be +[[BR]]
     - implementation of modifications related to exp. PHC_29 for comparison: daily SSS damping
     - implementation of the Kz tides which was missing, i.e. zdftmx.F90 zdf_oce.F90,  step.F90
     - implementation of dommsk.F90, diafwb.F90 et diawri.F90 modifications

     This run will be directly comparable with the one based on LIM 2.0 PHC_29[[BR]]
     '''Results:''' stops after 20 years run with salinity of -4 PSU in the Canadian North[[BR]]

     >>>> relaunch with this time '''nn_ico_cpl''' = 1[[BR]]
     '''Results:''' not sufficient, stops after 11 years [[BR]]

     29/12/2008 :[[BR]][[BR]]
     '''Results:''' stops again after relaunching after 19 years with negative salinity O(-10**4) PSU in i,j=65,146 [[BR]]
     whereas the initial state looks like normal, it seems to be related with an instability which grows in winter [[BR]]
     quickly.[[BR]]


     >>>> relaunch with '''nn_fsbc''' = 1 instead 5 i.e. coupling every time step with '''nn_ico_cpl''' = 0 [[BR]]
     '''Results:''' it seems to work fine but the cost is huge, ~250 years performed[[BR]]

=== Exp: USE_PHC_10_BIS === 


     # Based on exp. USE_PHC_10:
     - take into account bug corrections in:
           * sbcice_lim.F90
           * sbcmod.F90
           * limsbc.F90
           * sbcssm.F90
     - coupling method is different and better handled. Keep case (0) correcting 4 bugs:
           * module mean is now under root square for the 3 options 
           * add quotes in the leads fraction mean in option (1)
           * use mean values ss[uv]_m based on [uv]b instead [uv]n
