This week’s Imaggeo on Mondays is brought to you by Gert Verstraeten, who takes us through the formation of some of the striking landscapes in the Mediterranean – the badlands. For more than 7 years I have been performing research on reconstructing historic erosion rates in the Taurus Mountains in Southwest Turkey. Badlands are heavily eroded landscapes, where soft, clay-rich rocks and soils have ...[Read More]
GeoTalk: Simon Mudd
Today in GeoTalk, we’re talking to Simon Mudd, an exceptional and forward-thinking geomorphologist. First, could you introduce yourself and let us know a bit about what you are currently working on? I am lecturer in Landscape Dynamics at the University of Edinburgh, where I have been since 2007. Before that I was a post-doc at Vanderbilt University, in Nashville Tennessee. I received my PhD from V ...[Read More]
Imaggeo on Mondays: Aerosols over Hurricane Irene
This image – rather than our usual Imaggeo photo – is a simulation representation of Hurricane Irene, as it moved up the coast of the United States. The red-yellow areas in the image represent regions with high aerosol concentration that have been swept upwards in convective clouds and the blue areas are clean regions. The aerosols enter Irene along rain bands, before being wrapped into the centre ...[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]
