Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.Abstract We investigate implications of the recent change in basal melt rates from 93 Antarctic ice shelves from the 1990s to 2006–2016 (223 Gt yr−1 on average) on Southern Ocean climate using a fully coupled model. The most prominent response is significant increased sea ice coverage in the northern Amundsen Sea and decreased sea ice coverage in the ...

Patterns in glacial-earthquake activity around Greenland, 2011–13
Journal of Glaciology, 2017 Glacial earthquakes are caused by large iceberg calving events, which are an important mechanism for mass loss from the Greenland ice sheet. The number of glacial earthquakes in Greenland has increased sixfold over the past two decades.

Seismic Clues Reveal the Mechanisms Behind Iceberg Calving
Eos, 2016 Scientists combine models and video footage of iceberg calving to analyze the potential of seismology to unravel physical processes behind the breakup of ice sheets.

Prospects for seasonal forecasting of iceberg distributions in the North Atlantic [PDF]
, 2017 An efficient approach to ocean–iceberg modelling provides a means for assessing prospects for seasonal forecasting of iceberg distributions in the northwest Atlantic, where icebergs present a hazard to mariners each spring.

Journal of Quaternary Science, Volume 41, Issue 1, Page 4-24, January 2026.ABSTRACT The sediment signature of glacial erosion products exported from Hudson Strait to the Labrador Sea during Hudson Strait Heinrich (HS‐H) events is evaluated using four distinct proxies: paired δ18Ο and δ13C data on the carbonate fraction, εNd and U–Pb isotopes in the silicate fraction, the mineral composition of the <2 mm bulk sediment fraction,

Centurial‐millenial ice‐rafted debris pulses from ablating marine ice sheets [PDF]
, 2001 We use an ice‐sheet model to show that (i) margins of marine ice‐sheets can be expected to be frozen to the bed, except where ice‐streams discharge; (ii) 20–50km retreats induced by ablation rates of 2 m/yr provide sufficient debris flux through the ...

Assessing potential impacts of black bear predation on neonatal mortality in boreal caribou
The Journal of Wildlife Management, Volume 90, Issue 1, January 2026.We used simulations to show that even if caribou give birth in areas with the least chance of encountering a black bear, there are so many bears on the landscape that predation risk for caribou calves can still be quite high. Bear densities used in our simulation were typical for the boreal forest.

Massive Antarctic Icebergs May Calve at Random
EosThe first analysis of extreme calving events in Antarctica finds no correlation with climate change, highlighting the significance of common, smaller calving events for ice loss and instability.

Evaluation of Iceberg Calving Models Against Observations From Greenland Outlet Glaciers
Journal of Geophysical Research: Earth Surface, 2020 AbstractFrontal ablation processes at marine‐terminating glaciers are challenging to observe and difficult to represent in numerical ice flow models, yet play critical roles in modulating ice sheet mass balance. Current ice sheet models typically rely on simple iceberg calving models to prescribe either terminus positions or iceberg calving rates, but ...
