With the ongoing, sustained and rapid warming of the high Arctic, the mass loss of the Queen Elizabeth Islands
area is likely to continue to increase significantly in coming decades," Romain Millan, an Earth system science doctoral student at the university and lead author of the study, said in (https://www.
Maximum accumulation occurs in the summer and early fall (July-October), and analysis of shallow firn cores suggests that interannual variability in accumulation rates is linked to changes in sea ice extent and concentration in the region surrounding the Queen Elizabeth Islands, as well as to changes in the trajectory of air masses reaching the ice cap during this period (Colgan and Sharp, 2008).
Interannual variations in melt duration are closely related to July 500 mb heights over the Queen Elizabeth Islands because of their impact on near-surface air temperature gradients: high mean geopotential heights result in shallow surface air temperature lapse rates and increased melt extent and duration, while low heights produce steep lapse rates and reduced melt extent and duration (Wang et al.
