Some Aspects of Uncertainty in Predicting Sea Ice Thinning - Arctic Sea Ice Decline: Observations, Projections, Mechanisms, and Implications - page 66

Plate 2 (a) Annual mean sea ice thickness in the normal control with contour of 15% ice concentration for March (solid)
and September (dashed) for the control (black) and 1979-2000 passive microwave (green) [ Comiso , 1995]. (b) Annual
mean thickness difference between perturbed and control. (c) Annual mean thickness difference between fixed-albedo
perturbed and control.
