GeoSciences Column: Is smoke on your mind? Using social media to assess smoke exposure from wildfires
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]

Image of the Week – Summer is fieldwork season at EastGRIP!
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]

Too early seen unknown, and known too late!
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]

Minds over Methods: Block modeling of Anatolia
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]

Imaggeo on Mondays: Tongue of a small giant
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]

Image of the Week — High altitudes slow down Antarctica’s warming
When it comes to climate change, the Arctic and the Antarctic are poles apart. At the north of the planet, temperatures are increasing twice as fast as in the rest of the globe, while warming in Antarctica has been milder. A recent study published in Earth System Dynamics shows that the high elevation of Antarctica might help explain why the two poles are warming at different speeds. The Arctic vs ...[Read More]

GeoPolicy: What are science-policy placements and are they for you?
This month’s GeoPolicy blog will examine science-policy internships, fellowships, secondments and pairing-schemes in closer detail – highlighting the reasons for undertaking a placement and interviewing Dr Michelle Cain, an EGU member who participated in NERC’s Policy Placement Fellowship Scheme Science-policy placements provide scientists with the opportunity to use their knowledge within a ...[Read More]

Pre-plate-tectonics on early Earth: How to make primordial continental crust
The sequence of events before continental crust formation has long been contested. Numerical simulations performed by Rozel and colleagues imply that the key to the puzzle could lie in the intrusive magmatism. Despite several decades of research on the topic, the trigger of proto-continental crust formation on early Earth remains an enigma. However, magmatic processes may hold the key to unravelli ...[Read More]
