    2018The friction velocity ust2s() is computed at T-point. To do so, we must compute a mean 
    2119of speed velocities using velocities around T-point at i,j location and not i-1,j-1 location as it is done in the reference.[[BR]]

     63It results in a systematic icethickness decreasing O(-2/4 cm) in winter (March) along the sea-ice edge.[[BR]] 
     64Whereas "inside" Arctic area, it increases lightly icethickness O(+1/2 cm) with max. O(+10 cm) in the Hudson bay and off  
     65the North Siberian coast.[[BR]] 
     66The trend for ice fraction leads is the same, i.e. an decreasing between O(-1/5 %) at the sea-ice limit extent.[[BR]] 
     67But it doesn't change radically the icethickness differences with with the SDP3 New run. Patterns are still unchanged in Arctic.[[BR]] 
     68So even this bug correction doesn't explain the big differences between REF_CORE and SBC_NEW experiments.[[BR]]
