Researchers have generated the first dataset of water flow beneath the entire Antarctic Ice Sheet, which will lead to more accurate projections of sea level rise.
The team from the University of Waterloo modeled Antarctica’s subglacial environment. The dataset represents the researchers’ best approximation of what the water flow underneath the ice sheet might currently look like. The results include numerous subglacial lakes developing below ice streams in both East and West Antarctica, and an extensive network of subglacial water channels that discharge large fluxes of water under many major glaciers.
The model calculates how fast subglacial water is flowing and where it accumulates below the ice. It will significantly enhance the scientific community’s ability to accurately predict sea level rise from climate change.
