Submarine evidence of glacier surges

, 1986
Surges constitute a common form of glacier advance on the Svalbard archipelago (Liestd 1969), northwestern Barents Sea. The Austfonna ice cap (8100 km2) covers most of Nordaustlandet, the second largest island in the archipelago (Fig. 1).

A comparison of glacier melt on debris-covered glaciers in the northern and southern Caucasus [PDF]

, 2011
The glacier coverage in the Caucasus Mountains underwent considerable changes during the last decades. In some regions, the observed reduction in glacier area is comparable to those in the European Alps and the extent of supra-glacial debris increased on

Hematological and Genotoxic Effects of Subchronic Oral Exposure to a Mancozeb‐Based Fungicide in Female Mice

Journal of Applied Toxicology, EarlyView.
ABSTRACT The extensive use of pesticides in modern agriculture has raised increasing concerns regarding the potential biological effects of repeated exposure to pesticide residues and commercial formulations. Mancozeb is a widely used ethylene‐bis‐dithiocarbamate fungicide; however, information on its hematological and genotoxic effects following ...

Remote-sensing characterization of surging glaciers in High Mountain Asia in the past two decades

Frontiers in Earth Science
Glacier surge represents a special glacier behavior with abnormally high flow speeds, which can trigger catastrophic events, such as high-speed ice avalanches and glacial lake outburst floods, transforming landforms in the mountain cryosphere and ...

Ostracod faunal and geochemical evidence for the impact of Hoxnian (MIS 11c) sea levels in eastern England

Journal of Quaternary Science, EarlyView.
ABSTRACT Marine isotope substage 11c (~426–366 ka) is widely regarded as the most recent Pleistocene interglacial that is broadly analogous to the Holocene. The timing and magnitude of sea‐level changes during MIS 11 have been much debated, particularly concerning whether sea levels were significantly higher than during the Holocene. Empirical evidence

Basal stress controls ice-flow variability during a surge cycle of Hagen Bræ, Greenland

Journal of Glaciology, 2022
Basal conditions play an essential role in the dynamics of outlet glaciers, but direct observations at the bed of glaciers are challenging to obtain. Instead, inverse methods can be used to infer basal parameters from surface observations. Here, we use a

New Schmidt hammer exposure‐age dating calibrations for the Last Glacial Termination in NW Scotland: Development and application to undated Torridon Group sandstone surfaces in Wester Ross

Journal of Quaternary Science, EarlyView.
ABSTRACT An understanding of the terrestrial extent, retreat dynamics and climate–glacier coupling of ice masses during the Last Glacial Termination (LGT, ~18–11 ka) is often limited by a fragmentary geomorphological record and is dependent on precise, accurate and robust dating frameworks.

A tipping point for tipping points

Oikos, EarlyView.
Tipping points (TPs) – often understood as abrupt changes to a system – have become a popular framework for ecology and environmental science across spatial and temporal scales. The underlying, quantitative foundation of TP theory is built on mathematical models from catastrophe and predator–prey theories.

Surge Mechanisms of Garmo Glacier: Integrating Multi-Source Data for Insights into Acceleration and Hydrological Control

Remote Sensing
Understanding the mechanisms of glacial surging is crucial, as surges can lead to severe hazards and significantly impact a glacier’s mass balance. We used various remote sensing data to investigate the surge of Garmo Glacier in the western Pamir.

The 1982/83 surge and antecedent quiescent phase of Variegated Glacier: revising the original dataset for application in flow line models

Journal of Glaciology, 2017
The extensive dataset of Variegated Glacier's 1982/83 surge and antecedent quiescent phase is fragmentary and predominantly of flow line nature. Applying the raw centre line data in a flow line model to conduct research into the mechanism behind ...
