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 ...

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.

Buoyant forces promote tidewater glacier iceberg calving through large basal stress concentrations [PDF]
The Cryosphere, 2019 Iceberg calving parameterisations currently implemented in ice sheet models do not reproduce the full observed range of calving behaviours. For example, though buoyant forces at the ice front are known to trigger full-depth calving events on major ...

Surveying a Floating Iceberg With the USV SEADRAGON
Frontiers in Marine Science, 2021 The calving, drifting, and melting of icebergs has local, regional, and global implications. Besides the impacts to local ecosystems due to changes in seawater salinity and temperature, the freshwater influx and transport can have significant regional ...

Effect of topography on subglacial discharge and submarine melting during tidewater glacier retreat. [PDF]
, 2017 -We explored secular variations in subglacial discharge and submarine melting with an idealized model -Subglacial discharge increases as tidewater glaciers retreat along retrograde beds -Submarine melting depends on subglacial discharge and ...

Viscous and elastic buoyancy stresses as drivers of ice-shelf calving
Journal of Glaciology, 2020 The Antarctic Ice Sheet loses mass via its ice shelves predominantly through two processes: basal melting and iceberg calving. Iceberg calving is episodic and infrequent, and not well parameterized in ice-sheet models.

Semi-automated open water iceberg detection from Landsat applied to Disko Bay, West Greenland
Journal of Glaciology, 2019 Changes in Greenland's marine-terminating outlet glaciers have led to changes in the flux of icebergs into Greenland's coastal waters, yet icebergs remain a relatively understudied component of the ice-ocean system.

Observational constraints on the sensitivity of two calving glaciers to external forcings
Journal of Glaciology, 2023 Future mass loss projections of the Greenland ice sheet require understanding of the processes at a glacier terminus, especially of iceberg calving.

A Law for Small Scale, Continuous Calving [PDF]
, 2014 Ice shelves are formed by the viscous flow of inland ice into the ocean, they are floating and loosing mass by iceberg calving. There are two different kinds of calving: large tabular icebergs detach as singular events in time, and small scale calving ...

Distinguishing subaerial and submarine calving with underwater noise
Journal of Glaciology, 2022 Iceberg calving is one of the major mechanisms of ice loss from tidewater glaciers and ice sheets, but obtaining accurate estimates of ice discharge that are both continuous and accurate is a challenging task.
