The picture below shows several small glaciers surrounding the Greenland ice sheet, in Tassilaq, near Kulusuk, East Greenland. The dark lines are glacial moraines, responsible for the transport of rock material from mountains towards sea. The photographer, Romain Schläppy, highlights that “an important scientific topic consists to place the recent and ongoing Greenland warming in the broader conte ...[Read More]
GeoTalk: Suzanne Hangx on Carbon Capture & Storage
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]
