Ice sheet model for Integrated Earth-system Studies (IcIES) has
been developed to simulate Greenland and Antarctic ice sheets as
well as paleo-climate studies of past Northern Hemisphere ice
sheets.
Experimental design for Marine Ice-Sheet and Ocean Model Intercomparison Projects
(MISOMIP) has been launched (Asay-Davis 2015, GMDD).
Marine Ice-Sheet Intercomparison Projects third phase (MISMIP+)
is one of the three subprojects of MISOMIP, which focuses on the
comparison among `stand-alone' ice-sheet/ice-shelf models.
Seven sensitiivy experiments are proposed: each of them is a
100-year (optionaly 900-year) transient simulation under
prescribed basal melting below ice shelf.
This study reports preliminary tests of MISMIP+ experiments using
IcIES.
