A numerical model for meltwater channel evolution in glaciers [PDF]

open access: yesThe Cryosphere, 2012
Meltwater channels form an integral part of the hydrological system of a glacier. Better understanding of how meltwater channels develop and evolve is required to fully comprehend supraglacial and englacial meltwater drainage. Incision of supraglacial

Benthic microbial communities of coastal terrestrial and ice shelf Antarctic meltwater ponds. [PDF]

open access: yes, 2015
The numerous perennial meltwater ponds distributed throughout Antarctica represent diverse and productive ecosystems central to the ecological functioning of the surrounding ultra oligotrophic environment.

Quantifying the glacial meltwater contribution to mountainous streams using stable water isotopes: What are the opportunities and limitations? [PDF]

open access: yes, 2023
This study aims to determine the opportunities and limitations of using stable water isotopes to quantify the glacial meltwater contribution to mountainous streams. For this purpose, three partially glaciated catchments in the Swiss Alps were selected as

How Important Is Meltwater to the Chamkhar Chhu Headwaters of the Brahmaputra River?

open access: yesFrontiers in Earth Science, 2020
As our global climate warms, people, and economies utilizing water resources sourced by snow and ice melt in mountain areas are disproportionately affected relative to locations that rely on rainfall.

An ice-sheet scale comparison of eskers with modelled subglacial drainage routes [PDF]

open access: yes, 2015
Eskers record the signature of channelised meltwater drainage during deglaciation providing vital information on the nature and evolution of subglacial drainage.

A Simple Model for Deglacial Meltwater Pulses [PDF]

open access: yes, 2018
Evidence from radiocarbon dating and complex ice sheet modeling suggests that the fastest rate of sea level rise in Earth's recent history coincided with collapse of the ice saddle between the Laurentide and Cordilleran ice sheets during the last ...

Flow Routing for Delineating Supraglacial Meltwater Channel Networks

open access: yesRemote Sensing, 2016
Growing interest in supraglacial channels, coupled with the increasing availability of high-resolution remotely sensed imagery of glacier surfaces, motivates the development and testing of new approaches to delineating surface meltwater channels.

The Migration Pattern of Atrazine during the Processes of Water Freezing and Thawing

open access: yesToxics, 2022
Atrazine, one of the most commonly used herbicides in the world, is of concern because of its frequent occurrence in various water bodies and the potential threat it constitutes to ecosystems. The transport of contaminants in seasonally ice-covered lakes

Characterisation of bacterioplankton communities in the meltwater ponds of Bratina Island, Victoria Land, Antarctica [PDF]

open access: yes, 2014
A unique collection of Antarctic aquatic environments (meltwater ponds) lies in close proximity on the rock and sediment-covered undulating surface of the McMurdo Ice Shelf, near Bratina Island (Victoria Land, Antarctica).

Potential subglacial lake locations and meltwater drainage pathways beneath the Antarctic and Greenland ice sheets [PDF]

open access: yes, 2013
We use the Shreve hydraulic potential equation as a simplified approach to investigate potential subglacial lake locations and meltwater drainage pathways beneath the Antarctic and Greenland ice sheets. We validate the method by demonstrating its ability
