Enigmas at depth

The Geodynamics 101 series serves to showcase the diversity of research topics and/or methods in the geodynamics community in an understandable manner. In this week’s Geodynamics 101 post, Marcel Thielmann, Senior Researcher at the University of Bayreuth, discusses the possible mechanisms behind the ductile deformation at great depths that causes deep earthquakes.  Earthquakes are one of the expre ...[Read More]

Imaggeo on Mondays: Civita di Bagnoregio – the dying town

On top of a steep cliff standing out from the surrounding countryside, lies the small town of Civita di Bagnoregio, one of the most famous villages of Italy. It is often called the dying town, although more recently people have started to refer to it as fighting to live. What this little town is fighting against is the threat of erosion, as its walls are slowly crumbling down. Located in central I ...[Read More]

The bad, the good and the unpredictable: living with volcanoes / part 2

Before continuing, if you haven’t read it yet, catch up with the first part of this blog article by clicking on this link. The good Living with volcanoes is not all bad. Volcanoes provide a wealth of natural resources in the form of building materials, hot springs, freshwater and fertile soil. However, there are more hidden aspects, which was the focus of a recent collaboration with an archa ...[Read More]

Did you know… about the fluctuating past of north-east Greenland?

Recent geological data shows that during a very cold phase of our Earth’s climate (between 40,000 and 26,000 years ago), there was a huge expansion of polar ice sheets, yet the north-eastern part of the Greenland ice sheet was less extensive than today. How could this have occurred? In this post we shed light on the potential causes of this ice sheet behaviour. What do we know about present- ...[Read More]

Science as Type II Fun

Autumn had finally arrived – the weather had cooled down enough to start rock climbing outside again in southern Arizona. I was working on scaling a mountain’s cliff face tall enough to be a skyscraper with nearly 15 fellow scientists climbing routes around me. My palms were sweaty with nerves and my muscles were starting to get tired. I questioned what possessed me to climb this huge rock. ...[Read More]

Is the scientific community ready for open access publishing?

Is the scientific community ready for open access publishing?

How much we pay, as both scientists and the public, for publishing and accessing papers is a hot topic right across the academic community – and rightly so. Publishing houses, and their fees, are big, big business. To which journal we should submit our work is a regular decision we face. But what are the Green, Golden or Hybrid roads? How do pre- and post-prints fit into the journey? In this ...[Read More]

For Dummies – How do wildfires impact permafrost? [OR.. a story of ice and fire]

Wildfire – like the ones observed in the Northwest Territories, Canada in 2014 (Fig. 1) – is a natural part of permafrost landscapes, but fires are expected to get more frequent and severe as the climate warms. This could accelerate the degradation of permafrost, with negative consequences on the local and global scale! We have a pretty good understanding of how permafrost responds to fire t ...[Read More]
