On account of Mount Etna (Europe’s largest volcano), the island of Sicily is peppered with geological wonders. Starting with the summit craters of the volcano itself, right through to over 200 caves formed within lava tubes, the island is packed with volcanic sights.Chief among them is Gole dell ‘Alcantara, a system of gorges formed 8,000 …[Read More]

GeoSciences Column: The ‘dirty weather’ diaries of Reverend Richard Davis
Researching the Earth’s climate of the past, helps scientists make better predictions about how the climate and our environment will continue to be affected by, change and adapt to rising temperatures. One of the most invaluable sources of data, when it comes to understanding the Earth’s past climate, are historical meteorological records. Accounts of weather …[Read More]
Imaggeo on Mondays: A look inside a thunderstorm
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]
GeoTalk: Drilling into the crater which contributed to the demise of dinosaurs
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]
Imaggeo on Mondays: Why does a Norwegian glacier look blue?
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]
GeoPolicy: Living in a post-factual society and why it’s more important than ever for scientists to engage
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]
Imaggeo on Mondays: The odd ‘living’ rocks
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]
Imaggeo on Mondays: recording the Earth’s magnetic field one grain at a time
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]
Geosciences column: Making aurora photos taken by ISS astronauts useful for research
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]
Educators: Apply now to take part in the 2017 GIFT workshop!
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]
