PondInletThe fate of the Greenland ice sheet during the coming centuries is a major issue. Ice sheet decline will likely continue into the future, but it is unclear whether the current rate of mass loss will accelerate with ongoing oceanic and atmospheric warming. A shrinking ice sheet will not only result in rising sea level but will also inject meltwater into boundary currents near to the deep water formation areas (Hu et al. 2011). The current generation of climate models has a spatial resolution that may be insufficient to capture adequately the response of the ocean circulation to meltwater injections. Natural variations of ice volume during the deglaciation provide a means to test the performance of ice-sheet models and the response of the ocean to meltwater perturbations in high versus low-resolution models. Projects conducted within

ArcTrain will generate new and compile existing meltwater histories from paleoclimate archives and use the resulting information to test the behaviour of ice sheet and climate models. Ice sheet model development is also crucial to improve the representation of ice sheet-ocean coupling, marine ice sheet instabilities, and the effects of increased meltwater on ice sheet dynamics.
