Basal melt rates in equilibrium simulations of the Antarctic ice sheet under pre-industrial, 40 ka, and Last Glacial Maximum ocean conditions using the Parallel Ice Sheet Model (PISM 1.1)
We present basal melt rates for the ice shelves in equilibrium simulations of the Antarctic ice sheet (AIS), using the 3D thermodynamical Parallel Ice Sheet Model (PISM) version 1.1 with PICO as ocean component. The applied climate forcing consists of yearly mean present-day temperature and precipit...
