Today in GeoTalk, we’re talking to Suzanne Hangx, who explains the great potential of carbon capture and storage and the challenges emerging technologies, like CCS, face. First, could you introduce yourself and let us know what drew you to geomechanics? Let’s start with the introduction: I’m Suzanne Hangx and I currently work as a researcher on geomechanics for subsurface storage containment techn ...[Read More]
Imaggeo on Mondays: Mendenhall Glacier
Much of the Mendenhall River Basin is glaciated; indeed, the river flows out from under a glacier in the northern part of the valley and into a lake. This glacier, rather aptly, is known as Mendenhall Glacier, a 19 km long lake-calving monster in Alaska, USA. Meltwater from this glacier makes up the primary source of water for Mendenhall River, although several creeks also contribute to the flow, ...[Read More]
Geosciences Column: Tracing Toba
Large volcanic eruptions have a significant impact on the Earth’s climate as aerosols (including sulphur dioxide and water vapour), together with ash are released into the atmosphere and increase the amount of sunlight reflected back into space (the albedo). This increase in reflectance (or decrease in energy absorption) can cause widespread climatic cooling, known as a ‘volcanic winter’. However, ...[Read More]
Imaggeo on Mondays: Vanishing Lakes and Dry Arctic Landscapes
The Koukdjuak Plains (south-west Baffin Island, Canada) form a vast postglacial marine plain that borders the Foxe Basin, an area that has been progressively uplifted due to glacio-isostatic rebound following the end of the last glaciation about 6600 years ago. The weight of glaciers on the Earth’s crust causes the ground to be depressed, which, once the glacier melts, bounces back (at a geologica ...[Read More]
