Dynamics of glacier calving at the ungrounded margin of Helheim Glacier, southeast Greenland. [PDF]

J Geophys Res Earth Surf, 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.

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 ...

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 ...

Internal tsunamigenesis and ocean mixing driven by glacier calving in Antarctica. [PDF]

Sci Adv, 2022
Ocean mixing around Antarctica exerts key influences on glacier dynamics and ice shelf retreats, sea ice, and marine productivity, thus affecting global sea level and climate.

Controls on calving at a large Greenland tidewater glacier: stress regime, self-organised criticality and the crevasse-depth calving law

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.

Meltwater drainage and iceberg calving observed in high-spatiotemporal resolution at Helheim Glacier, Greenland

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.

Glacier dynamics near the calving front of Bowdoin Glacier, northwestern Greenland [PDF]

Journal of Glaciology, 2015
To better understand recent rapid recession of marine-terminating glaciers in Greenland, we performed satellite and field observations near the calving front of Bowdoin Glacier, a 3 km wide outlet glacier in northwestern Greenland.

Calving at Ryder Glacier, Northern Greenland [PDF]

Journal of Geophysical Research: Earth Surface, 2021
AbstractRecent evidence has shown increasing mass loss from the Greenland ice sheet, with a general trend of accelerated mass losses extending northwards. However, different glaciers have been shown to respond differently to similar external forcings, constituting a problem for extrapolating and upscaling data. Specifically, whilst some outlet glaciers

Calving cycle of Ninnis Glacier over the last 60 years

International Journal of Applied Earth Observations 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.
