C             ==> for non-zero AREA, units of ICEAGEAREA are seconds
C                 and actual ice age is ICEAGEAREA / AREA seconds
C     IceAgeTr(2) - effective sea ice age
C             at center of grid, i.e., tracer point
C             ==> for non-zero HEFF,
C                 units of ICEAGEVOL are seconds * meters
C                 and actual ice age is ICEAGEVOL / HEFF seconds
C     IceAgeTr(3), IceAgeTr(4) - effective sea ice age
