New Technique Reveals Iceberg Calving Process

Eos, 2017
Researchers used unmanned aerial vehicle data to model the growth of a fracture that broke a 1-kilometer-long iceberg off a Greenland glacier.

Brief Communication "The 2013 Erebus Glacier Tongue calving event" [PDF]

The Cryosphere, 2013
The Erebus Glacier Tongue, a small floating glacier in southern McMurdo Sound, is one of the best-studied ice tongues in Antarctica. Despite this, its calving on the 27 February 2013 (UTC) was around 10 yr earlier than previously predicted.

Antarctic iceberg melt rate variability and sensitivity to ocean thermal forcing

Journal of Glaciology, 2023
Changes in iceberg calving fluxes and oceanographic conditions around Antarctica have likely influenced the spatial and temporal distribution of iceberg fresh water fluxes to the surrounding ocean basins.

Monitoring the Petermann Ice Island with TanDEM-X [PDF]

, 2012
This paper presents the processing of TanDEM-X acquisitions for the monitoring of the topography of the Petermann ice island. In this particular case the area under study is continuously moving and the acquisition geometry is changing, so the processing ...

Micro‐habitat selection by boreal woodland caribou improves access to food

Wildlife Biology, EarlyView.
Bio‐logging sensors attached to radiotelemetry receivers have great potential to transform our understanding of the ecological, physiological, and energetic constraints that shape patterns of wildlife movement under field conditions. We used video camera collars to assess microhabitat selectivity by woodland caribou Rangifer tarandus in boreal forests ...

47 Years of Large Antarctic Calving Events: Insights From Extreme Value Theory

Geophysical Research Letters
Massive calving events result in significant instantaneous ice loss from Antarctica. The rarity and stochastic nature of these extreme events makes it difficult to understand their physical drivers, temporal trends, and future likelihood. To address this

Stratigraphic evidence for modern‐like glacier extents in south‐central Alaska within the last glacial period (MIS 3)

Boreas, EarlyView.
The last (Wisconsinan) glacial period was punctuated in North America by two glacial maxima, known as the Early and Late Wisconsinan glaciations. In Alaska, these maxima and their subsequent retreats have been the object of dating efforts to reconstruct local climatic events and compare them to global trends.

Icebergs, jigsaw puzzles, and genealogy: automated multi-generational iceberg tracking and lineage reconstruction [PDF]

The Cryosphere
Tabular icebergs calve from ice shelves and glaciers in Antarctica, Greenland, and northern Ellesmere Island. These “ice islands”, as they are referred to in the Arctic, drift, melt, and fragment, contributing freshwater and nutrients to the ocean ...

Understanding of an Iceberg Breaking Off Event Based on Ice-Front Motion Analysis of Amery Ice Shelf, Antarctica

Remote Sensing, 2021
On 26 September 2019, a massive iceberg broke off the west side of the Amery Ice Shelf (AIS) in East Antarctica. Since 1973, the AIS calving front has steadily advanced at a rate of 1.0 km yr−1. However, the advancement rate of the central portion of the
