This week’s Imaggeo on Monday’s post, captured by Maksim Cherviakov, shows students from Saratov National Research University practicing a method to measure lake ice thickness. The students are using an ice auger to manually burrow through the ice. Afterwards, the ice depth is recorded using a tape measure. “We measure ice thickness every year on the lakes located in the floodplain of the Vo ...[Read More]
On the Brunt Ice Shelf, Antarctica, a never-observed-before migration has just begun. As the pale summer sun allows the slow ballet of the supply vessels to restart, men and machines alike must make the most of the short clement season. It is time. At last, the Halley VI research station is on the move! Halley, sixth of its name Since 1956, the British Antarctic Survey (BAS) has maintained a resea ...[Read More]
Geotalk is a regular feature highlighting early career researchers and their work. In this interview we speak to Bert Wouters, a polar scientist at the University of Utrecht, and winner of one of the 2016 Arne Richter Awards for Outstanding Young Scientists. At a time when the polar regions are facing increasing challenges resulting from climate change, understanding how they might respond to them ...[Read More]
Last year the European Commission appointed a panel of world leading scientists to advise on key science policy issues. In November, the panel issued their first recommendation report focusing on CO2 vehicle emissions. The month’s GeoPolicy post takes a closer look at this high-level advisory panel and the recommendations they have published. In 2015, the Scientific Advice Mechanism (SAM) w ...[Read More]
On May 18th 1980 Mount St Helens (an active stratovolcano of the Cascades located in the North West US), erupted explosively following a magnitude 5.1 earthquake. The quake triggered a devastating landslide which swept away the volcano’s northern flank – in what is the largest debris avalanche recorded on Earth to date. Removal of a section of the edifice depressurised the volcano’s magmatic ...[Read More]
Much like trees, clam shells have growth rings. The chemistry of these rings can be used as a proxy for ocean chemistry. Recently, an international team of scientists used the growth rings found in shells of Arctica islandica to produce an annual absolutely dated marine δ18O record for the last millennium which was published in Nature Communications. The record represents the first fine scale arch ...[Read More]

The EGU General Assembly brings together geoscientists from all over the world to one meeting that covers all disciplines of the Earth, planetary and space sciences. The conference is taking place in Vienna on 23–28 April 2017, providing an opportunity for both established scientists and early career researchers to present their work and discuss their ideas with experts in all fields of the geosci ...[Read More]
Are you attending the AGU Fall Meeting in San Francisco next week (12th-16th December?) If so come and visit the EGU booth! You’ll find us in the Exhibition Hall in Booth 1231, just opposite the Recharge Lounge (top right of the exhibition hall). You can find us on the map of the exhibition hall online. In attendance will be the EGU’s Executive Secretary (Philippe) and the Communications Officer ( ...[Read More]
Have you ever thought of using gelatin in the lab to simulate the brittle-elastic properties of the Earth’s crust? Stefano Urbani, PhD student at the university Roma Tre (Italy), uses it for his analogue experiments, in which he studies the controlling factors on dike propagation in the Earth’s crust. Although we share this topic with our sister division ‘Geochemistry, Mineralogy ...[Read More]
