Science / project summary
Recent changes, including the dramatic speedups of several large outlet glaciers, and increased rates of surface melting, have increased Greenland’s contribution to sealevel rise from near zero in the 1990s to a large negative imbalance today. Poor knowledge of the processes driving these changes is one of the main limitations on prediction of future ice sheet contributions to sea level rise. An increasing number of observations point towards the influence of coupled ocean-ice-atmospheric processes in modulating ice sheet mass balance and outlet glacier behavior, but most studies are limited to the past few decades restricting our ability to extrapolate these relationships over longer time periods, given their high inter-annual variability. This project will further the understanding of ocean-ice-atmosphere interaction around the Jakobshavn Isbrae and Disko Bay region of west Greenland, with a particular focus on the role of sea surface temperature and sea ice variability in modulating past outlet glacier behavior and ice sheet/cap mass balance (snowfall and melt) over the past two centuries.
