Processes, drivers, Prediction: modeling the History and Evolution of Thwaites (PROPHET)
PROPHET is a modelling project intended to reduce uncertainty in near-future projections of the evolution of Thwaites Glacier. This will be achieved by improving the representation of several key processes that are not currently characterised well in large scale ice-flow models, and by determining the relative importance of different external drivers of change. Using coupled ice-ocean models, predictions will be made of the future ice loss from Thwaites Glacier and its contribution to sea level rise.
An international team of researchers has combined satellite imagery and climate and ocean records to obtain the most detailed understanding yet of how the West Antarctic Ice Sheet – which contains enough ice to raise global sea level by 3.3 metres – is responding to climate change. The researchers, several of whom are part of the International Thwaites Glacier Collaboration, found that the pace and extent of ice destabilisation along West… more
Hidden from view by ice kilometres thick, there is a vast network of lakes and streams under the Antarctic ice sheet. Using a decade of altimetry data from European Space Agency’s (ESA) CryoSat satellite, researchers at the University of Edinburgh, including a scientist with the PROPHET project of the International Thwaites Glacier Collaboration (ITGC), have made an unexpected discovery about how lakes beneath Thwaites Glacier drain and recharge… more
New study provides first evidence that thinning Antarctic ice shelves instantaneously result in more ice into the sea
Researchers have produced the first physics-based quantifiable evidence that thinning ice shelves all around Antarctica result in an instantaneous response sending more ice flowing from the land into the ocean.
