When I think of snow, I tend to either think about the bright white ski slopes in the mountains or the large white areas in the Arctic. However, natural phenomena can lead to colorful snow. Our Image of the Week shows snow can be green! Snow can also turn orange, pinkish, grey and even yellow… But where do these different shades of snow come from? White The most common color of snow is white (see ...[Read More]
The Geodynamics 101 series serves to show the diversity of topics and methods in the geodynamics community in an understandable manner for every geodynamicist. PhD’s, postdocs, full professors, and everyone in between can introduce their field of expertise in a lighthearted, entertaining manner and touch on some of the outstanding questions and problems related to their method of choice. Thi ...[Read More]
Earth is spectacularly beautiful, especially when seen from a bird’s eye view. This image, of a sweeping pattern made by a river in Iceland is testimony to it. The picture shows river Leirá which drains sediment-loaded glacial water from the Myrdalsjökull glacier in Iceland. Myrdalsjökull glacier covers Katla, one of Iceland’s most active and ice-covered volcanoes. A high sediment load (the suspen ...[Read More]

Wildfires have been raging across the globe this summer. Six U.S. States, including California and Nevada, are currently battling fierce flames spurred on by high temperatures and dry conditions. Up to 10,000 people have been evacuated in Canada, where wildfires have swept through British Columbia. Closer to home, 700 tourists were rescued by boat from fires in Sicily, while last month, over 60 pe ...[Read More]
As the days get very long, summer is a popular season for conducting fieldwork at high latitudes. At the North East Greenland Ice Stream (NEGIS), the East Greenland Ice-core Project (EastGRIP) is ongoing. Several scientists are busy drilling an ice core through the ice sheet to the very bottom, in continuation to previous years (see here and here). This year, amongst others, several members from t ...[Read More]
Romeo and Juliet famously had some identification problems: they met, fell in love, and only afterwards realised that they were arch enemies, which *spoiler* resulted in their disastrous fate. Oops. Of course, this could happen to anybody. However, we do not want this to happen to you! We want you to know who we, the EGU Geodynamics Blog Team, are! So, in order to prevent any mishaps during future ...[Read More]
How can we use GPS velocities to learn more about present-day plate motions and regional deformation? In this edition of Minds over Methods, one of our own blogmasters Mehmet Köküm shares his former work with you! For his master thesis at Indiana University, he used block modeling to better understand the plate motion and slip rates of Anatolia and surrounding plates. Using block modeling t ...[Read More]
In a world where climate change causes many mountain glaciers to shrink away, bucking the ‘melting’ trend is not easy. In today’s post, Antonello Provenzale, a researcher in Italy, tells us of one glacier in the Alps which is doing just that. Mountain glaciers are retreating worldwide, with the possible exception of the Karakoram area. For most glaciers, ablation (ice melt) durin ...[Read More]
