Additional steady-state simulations of Miocene Antarctic ice-sheet variability using 3D thermodynamical ice-sheet model IMAU-ICE
We supplement our previous dataset ( doi:10.1594/PANGAEA.939114 ), with six additional steady-state simulations of the Miocene Antarctic ice sheet using the reference Miocene settings. IMAU-ICE was run using a 40x40km grid covering the Antarctic continent. Initial conditions were obtained from recon...

IMAU-ICE was run using a 40x40km grid covering the Antarctic continent.

The simulations were forced by climate input data obtained from GENESIS simulations with varying CO2 levels (280 to 840 ppm) and Antarctic ice sheet cover (no ice to a large East-Antarctic ice sheet), and with present-day insolation. We utilized a matrix interpolation method to construct the time-varying climate forcing, based on the prescribed CO2 levels and ice cover simulated by IMAU-ICE. For each simulation, we provide the run script, 1D output variables including CO2 level and the sea level contribution of the Antarctic ice sheet, and 3D output variables including ice thickness, bedrock and surface height, surface mass balance, basal mass balance, ice velocities, and ice temperatures.
