Abstract
Higher latitudes have experienced a significant change in climate and physical processes within recent years. This study focuses on the Greenland Ice Sheet and surrounding ocean waters. It has been shown that relatively warm ocean waters may accelerate melt production of marine terminating glaciers. We explore and classify the pathways for the warmer Atlantic waters that reach the fjords along the coasts of Greenland. Additionally, given that the melt of these glaciers is accelerating, we look at the pathways of the low salinity melt waters from these coastal glaciers and where it is taken up in the surrounding basins. This analysis was carried out using an Arctic and North Hemisphere Atlantic (ANHA) configuration of the Nucleus for European Modelling of the Ocean (NEMO) ocean/sea-ice general circulation model run at both 1/4° and 1/12° resolution. Pathways were determined using the ARIANE Lagrangian float package using both forward and backward trajectories. Warm waters that reached the north and west coast of Greenland tended to be fed by the relatively warm and saline Irminger Current. The south east and the east Greenland coast tended to have warm waters advected to them through Nordic Seas.
