Dynamics of glacier calving at the ungrounded margin of Helheim Glacier, southeast Greenland [PDF]
Journal of Geophysical Research F: Earth Surface, 2015 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.

Glacier Calving in Greenland. [PDF]
Curr Clim Change Rep, 2017 In combination, the breakaway of icebergs (calving) and submarine melting at marine-terminating glaciers account for between one third and one half of the mass annually discharged from the Greenland Ice Sheet into the ocean. These ice losses are increasing due to glacier acceleration and retreat, largely in response to increased heat flux from the ...

Crevasse advection increases glacier calving
Journal of Glaciology, 2022 Iceberg calving, the process where icebergs detach from glaciers, remains poorly understood. Moreover, few parameterizations of the calving process can easily be integrated into numerical models to accurately capture observations, resulting in large ...

On the role of buoyant flexure in glacier calving [PDF]
Geophysical Research Letters, 2016 Abstract Interactions between glaciers and the ocean are key for understanding the dynamics of the cryosphere in the climate system. Here we investigate the role of hydrostatic forces in glacier calving. We develop a mathematical model to account for the elastic deformation of glaciers in response to three effects: (i) marine and lake‐

Calving cycle of Ninnis Glacier over the last 60 years
International Journal of Applied Earth Observation and Geoinformation, 2021 Iceberg calving is one of the contributing ways for the mass loss from ice shelves in Antarctica; the calving cycles of most ice shelves are quite long.

Underwater acoustic signatures of glacier calving [PDF]
Geophysical Research Letters, 2015 AbstractClimate‐driven ice‐water interactions in the contact zone between marine‐terminating glaciers and the ocean surface show a dynamic and complex nature. Tidewater glaciers lose volume through the poorly understood process of calving. A detailed description of the mechanisms controlling the course of calving is essential for the reliable ...

Surface wave generation due to glacier calving
Oceanologia, 2013 Coastal glaciers reach the ocean in a spectacular process called "calving". Immediately after calving, the impulsive surface waves are generated, sometimes of large height.

Journal of Glaciology, 2023 We investigate the physical basis of the crevasse-depth (CD) calving law by analysing relationships between glaciological stresses and calving behaviour at Sermeq Kujalleq (Store Glacier), Greenland.

Deriving mass balance and calving variations from reanalysis data and sparse observations, Glaciar San Rafael, northern Patagonia, 1950–2005 [PDF]
The Cryosphere, 2011 Mass balance variations of Glaciar San Rafael, the northernmost tidewater glacier in the Southern Hemisphere, are reconstructed over the period 1950–2005 using NCEP-NCAR reanalysis climate data together with sparse, local historical observations of air ...

Journal of Glaciology, 2022 Marine-terminating glaciers lose mass through melting and iceberg calving, and we find that meltwater drainage systems influence calving timing at Helheim Glacier, a tidewater glacier in East Greenland.
