!  Notes:
! ----------------------- 

  Stability problems:
    Problem 1:  Ocean instability in Denmark Strait
    Contact:  Gokhan
    Solution:  Change code that sets tidal mixing levels (number of lowest kmt levels 
	that are made constant).  Rebuild and run.  Once you are past the
	problem point, reset to default.
	Default number of levels:  2
	$CASEROOT/SourceMods/src.pop2/vmix_kpp.F90.tm6             !  (6 levels)
	$CASEROOT/SourceMods/src.pop2/vmix_kpp.F90.tm6-4levels 	   !  (4 levels)

    Problem 2:  Atmospheric instability caused by ice sheets over N. America
    Contact:  Cecile
    Solution:  changed divergence damping in cam.buildnml.csh.
	default:  div24del2flag = 2
	option1:  div24del2flag = 4
