Dynamics of glacier calving at the ungrounded margin of Helheim Glacier, southeast Greenland
During summer 2013 we installed a network of 19 GPS nodes at the ungrounded margin of Helheim Glacier in southeast Greenland together with three cameras to study iceberg calving mechanisms. The network collected data at rates up to every 7 s and was designed to be robust to loss of nodes as the glacier calved. Data collection covered 55 days, and many nodes survived in locations right at the gl...

متن کاملGreenland outlet glacier ice - flow variability
1 I ce mass loss from the Greenland Ice Sheet is a primary contributor to global sea level rise. The rate of ice loss has accelerated over the last couple of decades and Greenland currently contributes about 0.7-1.1 mm/yr to sea-level rise (260-380 Gt/ice per year; Enderlin et al. 2014; Shepherd et al. 2012). Predicting the potential rate and limits of future mass loss requires a clear understa...
متن کاملDistinct patterns of seasonal Greenland glacier velocity
Predicting Greenland Ice Sheet mass loss due to ice dynamics requires a complete understanding of spatiotemporal velocity fluctuations and related control mechanisms. We present a 5 year record of seasonal velocity measurements for 55 marine-terminating glaciers distributed around the ice sheet margin, along with ice-front position and runoff data sets for each glacier. Among glaciers with subs...
متن کاملReconstruction Glacier Circus in volcanic craters (Case study Kurdistan Qorveh)
Extended abstract Introduction The attention of forefront foreign researchers has focused on glacier circus. Glacial cirque is the most important pattern of glacial erosion. Deep depressions with steep walls, flat floor or low slope, half-bowl shaped (crescent shaped) are created at high altitudes in the mountains margin by the erosion of mountain glacier (Ahmadi, Feiznia, 2012). Th...
