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

Seabed corrugations beneath an Antarctic ice shelf revealed by autonomous underwater vehicle survey: Origin and implications for the history of Pine Island Glacier [PDF]
, 2013 Ice shelves are critical features in the debate about West Antarctic ice sheet change and sea level rise, both because they limit ice discharge and because they are sensitive to change in the surrounding ocean.

Shoreline and deglaciation chronology in southeast Norway
Boreas, EarlyView.The postglacial relative sea level history is reconstructed in four areas of mid‐ and inner Oslofjorden in southeast Norway. The reconstructions are based on radiocarbon‐dated raised shoreline levels from 42 sites, mainly isolation basins, and limiting ages from four lakes above the marine limit.

Greenland iceberg melt variability from high-resolution satellite observations [PDF]
The Cryosphere, 2018 Iceberg discharge from the Greenland Ice Sheet accounts for up to half of the freshwater flux to surrounding fjords and ocean basins, yet the spatial distribution of iceberg meltwater fluxes is poorly understood.

Classification of calving fronts around Antarctica [PDF]
, 2012 Iceberg calving is the largest loss term in Antarctic mass balance. The iceberg areas vary from a few square meters (growler) to several hundred square kilometres (huge tabular icebergs or ice islands) and their shape (blocky, domed or tabular) depends ...

Changes in Imja Tsho in the Mount Everest Region of Nepal [PDF]
, 2014 Imja Tsho, located in the Sagarmatha ( Everest) National Park of Nepal, is one of the most studied and rapidly growing lakes in the Himalayan range. Compared with previous studies, the results of our sonar bathymetric survey conducted in September of ...

Securing the past for the future – why climate proxy archives should be protected
Boreas, EarlyView.Glaciers, corals, speleothems, peatlands, trees and other natural proxy archives are essential for global climate change research, but their scarcity and fragility are not equally recognised. Here, we introduce a rapidly disappearing source of palaeoclimatic, environmental and archaeological evidence from some 5000 years ago in the Fenland of eastern ...

The northern sector of the last British ice sheet : maximum extent and demise [PDF]
, 2008 Strongly divided opinion has led to competing, apparently contradictory, views on the timing, extent, flow configuration and decay mechanism of the last British Ice Sheet.

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.

The statistical physics of iceberg calving and the emergence of universal calving laws [PDF]
Journal of Glaciology, 2011 AbstractDetermining a calving law valid for all glaciological and environmental regimes has proven to be a difficult problem in glaciology. For this reason, most models of the calving process are semi-empirical, with little connection to the underlying fracture processes.
