By Bethan Davies / AntarcticGlaciers.org Introduction | Radio echo sounding | Satellite altimetry: elevation changes | Effects of active lakes on ice dynamics | Drilling projects | References Introduction The Antarctic continent is underlain by subglacial lakes. Despite the fact that they are overlain by several kilometres of ice, these lakes are interconnected and water…
By Bethan Davies / AntarcticGlaciers.org Introduction | Supraglacial hydrology | Englacial hydrology | Subglacial hydrology | Proglacial drainage | References Introduction Glacier hydrology is the study of the flow of water through glaciers. It is a mysterious world, where water running on the surface of the glacier disappears through cracks and holes in the glaciers,…
Uploaded to YouTube on Sep 15, 2011: Burden of Proof / David Mitchell follows his sustainability rant with one on saving the environment. There is always heated debate about global warming, but until there is proof it doesn’t exist, shouldn’t we be looking for solutions? David Mitchell, star of UK TV favourites Peep Show and…

A collection of science around subglacial glacier’s, cavities and about water pressure/water flow. Though someone pointed out that most of the items are focused on land based glaciers, rather than on the WAIS which is a marine ice sheet. However, i welcome all contribution in the comment section which helps to better understand marine ice…
Via Robertscribbler: In a July 18 testimony to Congress, Dr. Jennifer Francis, an atmospheric scientist from Rutgers and key innovator to understanding how climate change has brought about dangerous alterations to the Northern Hemisphere Jet Stream, provides five compelling reasons why we should all be quite concerned about human caused global warming. They include: 1.…
METOP-2 imagery reveals that there is a significant area of high methane concentration over Antarctica. A study paper from 2012 reported that as glaciers melt, gas could belch into atmosphere. Potential Methane Reservoirs Beneath AntarcticaAug. 29, 2012 — The Antarctic Ice Sheet could be an overlooked but important source of methane, a potent greenhouse gas,…
