Over the past few decades, the Arctic region has warmed more than any other on Earth. The Greenland Ice Sheet is losing mass faster than ever before, and is expected to keep melting with consequences for global sea-level rise and ocean circulation. At a media briefing, during the EGU’s General Assembly in April (stream it here), researchers presented new results on the factors that influence the G ...[Read More]

High peaks, winding river channels and a barren landscape all feature in today’s Imaggeo on Mondays image, brought to you by Katja Laute, a geomorphologist from Norway. This photo was taken from an airplane flying over the Zagros Mountains in Iran. The Zagros Mountain range stretches south and west from the borders of Turkey and Russia to the Persian Gulf, and is Iran’s largest mountain ran ...[Read More]

GeoEd: I’m a Geoscientist 2015

Laura Roberts-Artal May 29, 2015

Imagine a talent show where contestants get voted off depending on their skills in their area of choice. Then imagine that this talent show is populated by geoscientists with school students voting them off based on the scientist’s ability to communicate their research well. This is the basis of an educational initiative called I’m a Geoscientist, a spinoff of UK’s I’m a Scientist. I’m a Geoscient ...[Read More]

Tiny crinkly folds form the main basis of today’s Imaggeo on Mondays. Folding can occur on a number of scales; studying folds at all scales can reveal critical information about how rocks behave when they are squeeze and pinched, as described by Sina Marti, from the University of Basel. Although many geoscientists have seen such fold structures many times before, if you noticed the scale bar in th ...[Read More]
