Large-scale investigation into iceberg-tsunamis generated by various iceberg calving mechanisms [PDF]
Coastal Engineering, 2021 Abstract Mass balance analysis of ice sheets is a key component to understand the effects of global warming with iceberg calving as a significant contributor. Calving recently generated tsunamis of up to 50 m in amplitude endangering human beings and coastal infrastructure.

Do atmospheric rivers trigger tabular iceberg calving?
Journal of GlaciologyThe processes governing iceberg calving from ice shelves remain poorly understood. Recent studies suggest that anomalous atmospheric moisture transport events – atmospheric rivers – can act as triggers for calving.

Large-scale experiments into the tsunamigenic potential of different iceberg calving mechanisms. [PDF]
Sci Rep, 2019 AbstractMass balance analysis of ice sheets is a key component to understand the effects of global warming. A significant component of ice sheet and shelf mass balance is iceberg calving, which can generate large tsunamis endangering human beings and coastal infrastructure.

Iceberg Calving: Regimes and Transitions
Annual Review of Earth and Planetary Sciences, 2023 Uncertainty about sea-level rise is dominated by uncertainty about iceberg calving, mass loss from glaciers or ice sheets by fracturing. Review of the rapidly growing calving literature leads to a few overarching hypotheses. Almost all calving occurs near or just downglacier of a location where ice flows into an environment more favorable for calving ...

A 15-year circum-Antarctic iceberg calving dataset derived from continuous satellite observations [PDF]
Earth System Science Data, 2021 Iceberg calving is the main process that facilitates the dynamic mass loss of ice sheets into the ocean, which accounts for approximately half of the mass loss of the Antarctic ice sheet.

Quantifying iceberg calving fluxes with underwater noise [PDF]
The Cryosphere, 2020 Accurate estimates of calving fluxes are essential in understanding small-scale glacier dynamics and quantifying the contribution of marine-terminating glaciers to both eustatic sea-level rise (SLR) and the freshwater budget of polar regions.

Ocean tides trigger ice shelf rift growth and calving [PDF]
Nature CommunicationsTabular iceberg calving reduces ice-shelf extent, affecting ocean circulation and ice-sheet stability. Here we present detailed observations of a rift on the Brunt Ice Shelf, East Antarctica, from 2017-2023 and its behaviour in the lead up to calving in ...

Efficient Location and Extraction of the Iceberg Calved Areas of the Antarctic Ice Shelves [PDF]
Remote Sensing, 2020 Continuous, rapid, and precise monitoring of calving events contributes to an in-depth understanding of calving mechanisms, which have the potential to cause significant mass loss from the Antarctic ice sheet.

Calving seismicity from iceberg–sea surface interactions [PDF]
Journal of Geophysical Research, 2012 Iceberg calving is known to release substantial seismic energy, but little is known about the specific mechanisms that produce calving icequakes. At Yahtse Glacier, a tidewater glacier on the Gulf of Alaska, we draw upon a local network of seismometers and focus on 80 hours of concurrent, direct observation of the terminus to show that calving is the ...
