Fig. 6: Influence of bed topographic changes on ice sheet response to oceanic cooling.
From: Ocean cavity regime shift reversed West Antarctic grounding line retreat in the late Holocene

Predicted grounding line migration of the ice sheet advance experiments using different bed topography changes. The minimum grounding line extent at 1.6 ka BP is shown by the dark red line, and position changes every 200 years are shown, darkening in scale from gray to black. a Fixed bed topography at 2 ka BP shown in m above sea level; b bed topography change (m) from 2 to 0 ka BP of the ice sheet model (ISM) with simple viscoelastic deformation; c bed topography change (m) from 2 to 0 ka BP of the glacioisostatic adjustment model with weak Earth structure (GIAWE); d bed topography change (m) from 2 to 0 ka BP of the glacioisostatic adjustment model with strong Earth structure (GIASE).
