Iceland, the land of ice and fire, is well known for its volcanicity. Most famously, it is home to Eyjafjallajökull: the volcano which caused wide spread mayhem across European airspace when it erupted in 2010. But not all the local volcanic activity is unwelcome. High temperature geothermal areas are a byproduct of the volcanic setting and the energy released can be used to power homes and infras ...[Read More]
“Positive feedback” is a term that regularly pops up when talking about climate change. It does not mean good news, but rather that climate change causes a phenomenon which it turns exacerbates climate change. The image of this week shows a beautiful melt pond in the Arctic sea ice, which is an example of such positive feedback. What is a melt pond? The Arctic sea ice is typically non-smooth, and ...[Read More]

By: Sam Zipper, Postdoctoral Fellow, McGill University/University of Victoria When people think of groundwater in agricultural landscapes, pumping and irrigation are usually the first thing that comes to mind. However, groundwater can have a more subtle but extremely important impact on crop production when we decide to leave it underground: When there is shallow groundwater beneath an agricultura ...[Read More]
This year, the Young Geomorphologists from Germany invite all interested young researchers / students in geomorphology and related fields to join the 11th international Young Geomorphologists’ workshop at Ammersee, Germany, held from 19th-21st May 2017. The venue is located at a lake ca. 1 hour southwest of Munich. In a mixture of oral presentations, posters, a keynote and a short fieldtrip, ...[Read More]
Located in the North Atlantic Ocean, just south of the polar circle, Iceland is a highly fascinating land. Covered by some of the largest glaciers in Europe and hosting active volcanoes, geothermal sites and subglacial lakes, it is extremely dynamic in nature and ever changing. With this Image of the Week we will tell you a bit about the changing ice caps of Iceland and how we can monitor them fro ...[Read More]
Early career scientists (ECS) make up a significant proportion of the EGU membership and it’s important to us that your voices get heard. To make sure that happens, each division appoints an early career scientists representative: the vital link between the Union and the ECS membership. After tenure of two or four years, a few of the current ECS Representatives are stepping down from their post at ...[Read More]

On the blog today, Jennifer Ziesch, a researcher at the Leibniz Institute for Applied Geophysics, takes us on a tour of the Great Salt Lake, located in the north of Salt Lake City (Utah). Did you know it is one of the largest salt water lakes in the world? The large salt lake and Salt Lake City, named after the lake, lie on a flat plain about 1300 m above sea level. The salt lake is bordered to th ...[Read More]
Sea ice brine sampling is always great fun, but sometimes somewhat challenging ! As sea water freezes to form sea ice, salts in the water are rejected from the ice and concentrate in pockets of very salty water, which are entrapped within the sea ice. These pockets are known as “brines”. Scientists sample these brines to measure the physical and bio-geochemical properties, such as: tem ...[Read More]
