Accumulation
Up one levelIce sheet growth or shrinkage is closely linked to snow accumulation and its changes. Knowledge of the spatial and temporal pattern of accumulation rates is crucial in understanding the impact of the East Antarctic ice sheet on sea-level change. Shallow radar as well as ice cores will be used to determine accumulation rates. GPS yields important information about the surface topography, which influences the variations in accumulation.
