Fig.5. a-c. Determination of ice age distribution and thickness distribution in a grid cell extracted from the time sequence. a The image sequence showing
the deformation
of a grid cell. b Plot of area changes as a function of time, and age histograms computed from the area changes. c Plot of the freezing-degree
days
and the computed thickness of the ice. (1
