Hydraulic impacts of glacier advance over a sediment bed [PDF]

, 2006
A sedimentary sequence of till overlying a gravel aquifer was instrumented with water-pressure transducers prior to a small, anticipated surge of the margin of the glacier Breiðamerkurjökull in Iceland.

A framework for three-dimensional dynamic modeling of mountain glaciers in the Community Ice Sheet Model (CISM v2.2) [PDF]

Geoscientific Model Development
It is essential to improve our understanding of glaciers and their effects on sea levels, ecosystems, and freshwater resources in a changing climate. To this end, we implemented a framework for three-dimensional, high-resolution, regional-scale glacier ...

Monte Carlo ice flow modeling projects a new stable configuration for Columbia Glacier, Alaska, c. 2020 [PDF]

The Cryosphere, 2012
Due to the abundance of observational datasets collected since the onset of its retreat (c. 1983), Columbia Glacier, Alaska, provides an exciting modeling target.

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 ...

A minimal model of a tidewater glacier [PDF]

Annals of Glaciology, 2005
AbstractWe propose a simple, highly parameterized model of a tidewater glacier. The mean ice thickness and the ice thickness at the glacier front are parameterized in terms of glacier length and, when the glacier is calving, water depth. We use a linear relation between calving rate and water depth.

The distribution of basal motion beneath a High Arctic polythermal glacier [PDF]

, 2003
The longitudinal pattern of surface velocity of a large, predominantly colds polythermal glacier (John Evans Glacier, Ellesmere Island, Canada) was measured over summer and winter periods.

Molecular characterization of covRS mutations in M1UK Streptococcus pyogenes

FEBS Open Bio, EarlyView.
Group A Streptococcus (GAS) acquires covRS mutations driving a hypervirulent bacterial state, frequently associated with invasive disease‐like necrotizing fasciitis. We demonstrate that the newly emerged M1UK GAS lineage can also acquire these mutations.

Coherent scatterers detection: application over glacier terrain using TerraSAR-X time series data [PDF]

, 2011
This paper investigates the detection of Coherent Scatterers (CSs) in ice and glacier terrain by means of TerraSAR-X time series data in the test site of the Helheim Glacier in Greenland.
