This week’s contribution to Imaggeo on Mondays is a photograph of a mesocyclone – and its rotating wall cloud – photographed by Mareike Schuster, an atmospheric scientist from Freie Universität Berlin, Germany. The picture was taken in June 2012 near Cheyenne, Wyoming in the United States during a field campaign, ROTATE, led by the Center …[Read More]
Six months ago, somewhere in the tropical waters off the coast of Mexico, scientists began drilling into one of the most iconic geological features on Earth: the Chicxulub crater; the 66 million year old remnants of a deadly asteroid impact, thought to have contributed to the demise of dinosaurs and most other forms of life …[Read More]
This picture shows the outlet glacier Engabreen running down from the plateau of Svartisen in Norway. Svartisen ice cap comprises two glacier systems of which the Vestre (western) Svartisen is Norway’s second largest glacier. Located right at the polar circle, Svartisen covers a total of 369 km² of the Nordland region. These coastal mountains accumulate …[Read More]
Last week, the EGU Science Policy Fellow packed her bags and flew to Brussels. Now this wasn’t to sample some of the fine beers Belgium has to offer, but to attend the 2nd International Network on Government Science Advice (INGSA) Conference. This conference, co-organised by INGSA and the European Commission, aimed to discuss the major …[Read More]
Microbialites – structures which result from the interaction between microbes and sediments – have existed in the rock record since 3700 Ma ago until the present day. The presence of microbes in environments where mineral precipitation is prevalent, usually derives in the development of such chemical sedimentary structures. This can take place in marine, non-marine, …[Read More]
The Earth’s magnetic field extends from the core of the planet, right out to space. It is an invisible, butterfly-like, shield which protects us against the harmful particles ejected by solar flares. In addition, it guards us from atmospheric erosion and water loss caused by solar wind. But how do scientists study the Earth’s magnetic …[Read More]
It’s a clear night, much like any other, except that billions of kilometers away the Sun has gone into overdrive and (hours earlier) hurled a mass of charged particles, including protons, electrons and atoms towards the Earth. As the electrons slam into the upper reaches of the atmosphere, the night sky explodes into a spectacular …[Read More]
The General Assembly is not only for researchers but for teachers and educators with an interest in the geosciences also. Every year the Geosciences Information For Teachers (GIFT) is organised by the EGU Committee on Education to bring first class science closer to primary and high school teachers. The topic of the 2017 edition of …[Read More]
That soils are vital to secure our future supplies of water, food, as well as aiding adaptation to climate change and sustaining the planet’s biosphere is a subject we’ve featured on the blog as recently as the summer. That’s because never have humans been more out of touch with the vital importance of this natural …[Read More]
As far as blogging milestones go, today is pretty special. This is GeoLog’s 1000 post! Since the EGU’s official blog launched back in March 2010 (that’s right, there’s over 6 years of back catalogue for you to enjoy!), we’ve shared posts about research spanning almost every discipline in the Earth sciences; highlighted member’s adventures in …[Read More]
