Fig. 2: Modeled melt production due to deglaciation of Iceland ice sheet.
From: Deglaciation-enhanced mantle CO2 fluxes at Yellowstone imply positive climate feedback
The ice sheet is represented by the green parabola at a given time step and by the dashed black line at its maximum extent. Rates of pressure change are colored teal-brown (a, c) and rates of melt fraction change are colored blue-orange (b, d). Top row shows a model time step prior to any glacial loading/unloading, while bottom row shows a time step 500 years following deglaciation onset. Red arrows show mantle flow (arrow size is scaled to velocity magnitude); the thick black line is the lithosphere-asthenosphere boundary (LAB), at T = 1300 °C.
