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 boundary dynamics are divided into three ...[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 at all? These type of questions inspired me to think about where atmospheric chemistry has ...[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 Byerlee’s law (Bye ...[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 the Conservation of Waterlogged, Organic, Archaeological mat ...[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 banner clouds at the leeward site of the Fitz Roy mountain an ...[Read More]
Furious yet disillusioned by a bunch of anonymous reviewers, of which most have provided zero insight through their nugatory reviews and displaying unambiguous bias towards a non-inflammatory, well-worded and a scientifically substantiated manuscript, Txabi demands to know: Why are many reviewers still insisting on anonymity? Dear Txabi, There is indeed such a segment of the academic community, wh ...[Read More]
There were a lot of big changes to the EGU’s science for policy programme in 2020 with many of our activities, such as the annual science for policy event and science-policy pairing scheme, moving online. But 2021 promises to be an even bigger year with a greater number of opportunities to engage and activities becoming even more accessible! So, if you haven’t engaged with science for policy befor ...[Read More]
Icebergs are ubiquitous in Greenland’s fjords, melting and releasing freshwater as they float towards the open ocean. The amount of freshwater released from these icebergs can be vast – the equivalent of around 50,000 Olympic swimming pools per day in some fjords. New research reveals that this freshwater causes fjord currents to speed-up, which can actually increase the amount of heat delivered t ...[Read More]
Like all people, geoscientists can sometimes forget the importance of language. How scientists use language is important because it not only allows us to communicate effectively with different groups, from policymakers to concerned citizens and other researchers, but it can also influence how people respond on an emotional or personal level. The way we use language can even influence how much som ...[Read More]
One hundred years back, Leopold Kober first introduced the term “Kratogen”. With time, the concept of kratogen has evolved, and they are now known as cratons. In this week’s news and views, Jyotirmoy (@GeophyJo), a PhD student from the Indian Institute of Science revisits the history of craton science: how the craton concept has evolved and what are the modern problems related to them. &nbs ...[Read More]
