The mysterious appearance and disappearance of the Weddell Polynya, a giant hole in the sea ice cover, has long puzzled scientists. Recent work reveals that the polynya is initiated and maintained by gigantic and formidable atmospheric currents: atmospheric rivers! Read on to find out more… Each year, approximately 15 million square kilometers of ice forms …[Read More]

Having spent the last eight years in education, it’s time to start a new job! …[Read More]
Ramsay’s 1980 important contribution is a practical and theoretical handbook about shear zones, where the reader can find a detailed classification of shear zones, their description, and mathematical explanation. A definition of the concept of shear zones opens the article, followed by the shear zones classification into three types, namely brittle (e.g., Fig. 1a), brittle-ductile …[Read More]
2020 left your head spinning? This week Derek Neuharth from GFZ Potsdam introduces us to the spinning microplates that can be found in extensional plate boundaries such as the East African Rift System and the East Pacific Rise. Divergent plate boundaries Microplates are enigmatic features that form in the boundaries between tectonic plates. Generally, plate …[Read More]

Hopefully, by the end of 2021, the vaccination campaign will help combat the pandemic, and allow us to go back …[Read More]
The genesis of the idea to explore the influence of certain papers on shaping the field of tropospheric chemistry came when editing a textbook chapter I had written a decade earlier. As I edited it I thought, what really is new; text-book worthy over the last 10 years? In some senses what is text-book worthy …[Read More]
In 1980 Brace and Kohlstedt published a short paper that constrains the strength of continental lithosphere by extrapolating laboratory measurements of rock strength to geological conditions. Their approach follows earlier work by Goetze and Evans (1979) and relies on two key considerations. First, the brittle strength is given by the frictional strength of rocks following …[Read More]
Recently, the European Geosciences Union (EGU) started to support a new type of event called ‘Campfires’ that will give the Divisions the freedom to run online interactive events in a way that suits their needs. This allows the EGU Divisions to encourage interactions in their research communities through virtual informal meetings. In this framework, and …[Read More]
Happy New Year! It’s January, and time for us to continue our monthly series of blog posts dedicated to highlighting the great work carried out by technicians, laboratory assistants, and research support staff in soil science. This month, we sat down (virtually, of course) with Jonathan J. Gottlieb (J.J.), the Head of the Laboratory for …[Read More]
The indigenous name of the 3405 meter high Fitz Roy mountain in Patagonia, on the border between Argentina and Chile, is frequently translated as “smoking mountain”. This photo may visually explain an origin of this name. On the day the photo was taken, vortices downwind of the peak drew warmer, humid air from below, forming …[Read More]
