Nioghalvfjerdsfjorden

gsh_las_79N
Also known as 79º North Glacier, Nioghalvfjerdsfjorden is one of the largest glaciers in Greenland. It is one of the tributaries of the North East Greenland Ice Stream (NEGIS), which is underlain by (relatively) warm(er) continental crust, and has a bed that is below sea level up until the ice divide. Even though Nioghalvfjerdsfjorden is relatively slow-moving right now, it has a large potentially-unstable catchment basin and terminus region that we are studying with remote sensing and ground-based measurements. Colleagues at WHOI (Fiamma Straneo) are obtaining oceanography measurements being used to investigate the link between ocean circulation and ice flow. Pasted Graphic
