Greenland Fracture Zone–East Greenland Ridge(s) revisited: Indications of a C22-change in plate motion?

Rapid retreat and acceleration of Helheim Glacier, east Greenland

[1] A significant amount of the measured coastal thinning of the Greenland ice sheet may be due to recent acceleration of outlet glaciers. Using remote sensing, we measured two major periods of speedup on Helheim Glacier between 2000 and 2005 that increased peak speeds from approximately 8 to 11 km/yr. These speedups coincided with rapid retreats of the calving front, totaling over 7.5 km. The ...

The East Greenland Coastal Current: Structure, variability, and forcing

The subtidal circulation of the southeast Greenland shelf is described using a set of high-resolution hydrographic and velocity transects occupied in summer 2004. The main feature is the East Greenland Coastal Current (EGCC), a low-salinity, high-velocity jet with a wedge-shaped hydrographic structure characteristic of other surface buoyancy-driven currents. The EGCC was observed along the enti...

On the Consistency of Thermal Events in the East Greenland/West Greenland Current System and off Labrador

Based on conductivity, temperature, depth (CTD) measurements with rosette mounted bottle performed along standard oceanographic sections off Greenland, the consistency of thermal events was analyzed. High consistency of events was found for the sections off Southeast Greenland and West Greenland, low consistency was revealed for the northernmost section off East Greenland and the West Greenland...

Be ages from central east Greenland constrain the extent of the Greenland ice sheet during the Last Glacial Maximum

Traditional ice sheet reconstructions have suggested two distinctly different ice sheet regimes along the East Greenland continental margin during the Last Glacial Maximum (LGM): ice to the shelf break south of Scoresby Sund and ice extending no further than to the inner shelf at and north of Scoresby Sund. We report new Be ages from erratic boulders perched at 250ma.s.l. on the Kap Brewster pe...
