Characteristics of the 15-year surge of Mittie Glacier, SE Ellesmere Island, Canadian Arctic

Annals of Glaciology
A surge of Mittie Glacier, a 50 km-long tidewater outlet glacier of Manson Icefield, occurred between approximately 1992 and 2007. Velocities increased slowly at first, but then increased rapidly to reach a peak of 4800 m a−1 in early 1996, the highest ...

Automated Detection of Glacier Surges from Sentinel-1 Surface Velocity Time Series—An Example from Svalbard

Remote Sensing, 2023
Even though surge-type glaciers make up only a small percentage of all glaciers, related research contributes considerably to the general understanding of glacier flow mechanisms.

Influence of Habitat Use on Prey Capture Behavior and Kinematics in the Pyrenean Brook Newt (Calotriton asper)

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Caves are extreme environments that impose stringent selective pressures on organisms. Consequently, many cave dwellers show extreme adaptations such as the loss of eyes, depigmentation, and a low resting metabolic rate. Yet, how the initial stages of adaptation to these extreme environments take place remains poorly understood.

A distributed energy-balance melt model of an alpine debris-covered glacier [PDF]

, 2014
Distributed energy-balance melt models have rarely been applied to glaciers with extensive supraglacial debris cover. This paper describes the development of a distributed melt model and its application to the debris-covered Miage glacier, western ...

Characterizing the May 2015 Karayaylak Glacier surge in the eastern Pamir Plateau using remote sensing

Journal of Glaciology, 2016
We investigate an internal surge of Karayaylak Glacier, which was reported by the media in May 2015. To differentiate the May 2015 glacier surge from other glacier advances, we surveyed changes in velocity, crevasses and glacier area using Landsat 8 OLI ...

Glacier changes in the Karakoram region mapped by multimission satellite imagery [PDF]

The Cryosphere, 2014
Positive glacier-mass balances in the Karakoram region during the last decade have fostered stable and advancing glacier termini positions, while glaciers in the adjacent mountain ranges have been affected by glacier recession and thinning.

Compound Meteorological and Hydrological Hot‐Dry and Hot‐Wet Extremes Over Global Land Areas: Spatiotemporal Changes, Attribution, and Drivers

International Journal of Climatology, EarlyView.
The changes in joint return period of compound meteorological hot‐dry (CMHHE) and hot‐wet (CMHWE) and compound hydrological hot‐dry (CHHDE) and hot‐wet (CHHWE) extremes were attributed to changes in associated univariate extremes and their dependence.

Assessing the catastrophic break-up of Briksdalsbreen, Norway, associated with rapid climate change

, 2011
Recent research has raised concerns about the potential influence of rapid climate change on the stability of major ice sheets. The behaviour of glaciers is determined largely by the processes and conditions operating at their base.

Representing moisture fluxes and phase changes in glacier debris cover using a reservoir approach [PDF]

, 2014
Due to the complexity of treating moisture in supraglacial debris, surface energy balance models to date have neglected moisture infiltration and phase changes in the debris layer.

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
