Investigating the Hydrology of Ice Shelves, and Its Implications for Ice-Shelf Stability

Grant John Macdonald
Studies show that surface lakes that form on ice shelves can promote ice-shelf instability, which has consequences for wider ice-sheet stability. Meltwater on ice shelves will become increasingly pervasive due to climate change and it is therefore crucial that we improve understanding of ice-shelf hydrology and its implications for ice-shelf stability. First, we use remote sensing to analyze the seasonal evolution of surface lakes on Peter- mann Glacier’s floating ice tongue (a narrow ice shelf)....
