    7777In doing that we are closer to what is done in limdyn.F90 of the NEW SBC.[[BR]] 
    7878It results in a sea-ice surface temperature colder O(-1/2°C) than in SDP Ref mainly in the limit sea-ice extent.[[BR]] 
    79 And a systematic decrease of the icet thickness by O(-2/4 cm) over all the Arctic reaching in some area O(-10 cm) Hudson bay or near  
    80 the Bering strait.[[BR]] 
    81 So its impact is significant and must be take into account in the rewritten of this part in the NEW _SBC.
