Imaggeo on Mondays: Of ancient winds and sands

Snippets of our planet’s ancient past are frozen in rocks around the world. By studying the information locked in formations across the globe, geoscientist unpick the history of Earth. Though the layers in today’s featured image may seem abstract to the untrained eye, Elizaveta Kovaleva (a researcher at the University of the Free State in South Africa) describes how they reveal the secrets of anci ...[Read More]

Try something different at EGU 2018– choose a PICO session!

Some of the sessions scheduled for the upcoming EGU General Assembly are PICO only sessions. This means that, rather than being oral or poster format, they involve Presenting Interactive COntent (PICO). The aim of these presentations is to highlight the essence of a particular research area – just enough to get the audience excited about a topic without overloading them with information. What’s gr ...[Read More]

October GeoRoundUp: the best of the Earth sciences from around the web

Carbon dioxide plays a significant role in trapping heat in Earth’s atmosphere. The gas is released from human activities like burning fossil fuels, and the concentration of carbon dioxide moves and changes through the seasons. Using observations from NASA’s Orbiting Carbon Observatory (OCO-2) satellite, scientists developed a model of the behavior of carbon in the atmosphere from Sept ...[Read More]

The jelly sandwich lithosphere: elastic bread, the jelly, and gummy bears

The Geodynamics 101 series serves to showcase the diversity of research topics and methods in the geodynamics community in an understandable manner. We welcome all researchers – PhD students to Professors – to introduce their area of expertise in a lighthearted, entertaining manner and touch upon some of the outstanding questions and problems related to their fields. This month Vojtěch Patočka fro ...[Read More]

Eyes on the Sun

Eyes on the Sun

The Sun is a complex, dynamic ball of plasma which influences our lives. Studying the Sun is challenging because each of its layers have different composition, physics and wavelengths of emssion. Moving outwards from the photosphere (visible surface of the Sun), we have the chromosphere and the corona (hottest outermost layer). The solar plasma is in constant motion much like fiercely boiling wate ...[Read More]

Bárbara Zambelli Azevedo: Urban Geology and Underground Urbanisation

We have a vacancy for a science communication or science journalism student in Europe to work at the press office of the 2013 General Assembly, which is taking place in Vienna, Austria, from 07-12 April. Applications from geosciences students with science communication experience are also welcomed. The student will join the team assisting the EGU press officer and the journalists at the press cent ...[Read More]

Imaggeo on Mondays: Magnetic interaction

Space weather is a ubiquitous, but little known, natural hazard. Though not as tangible as a volcanic eruption, storm or tsunami wave, space weather has the potenital to cause huge economic losses across the globe. In Europe alone, the interaction of solar wind with our planet’s magnetosphere, ionosphere and thermosphere, could lead to disrutions to space-based telecommunications, broadcasti ...[Read More]

GeoPolicy: The importance of scientific foresight

GeoPolicy: The importance of scientific foresight

Many of the issues that society currently faces are complex and research on just one angle or area does not provide sufficient information to address the problem. These challenges are compounded when more than one region (or even the entire planet) is impacted. Many of the decisions and legislations passed by governments today will go on to impact how these issues either develop or are resolved ye ...[Read More]

Understanding the role of microbes in cold seep habitats

Understanding the role of microbes in cold seep habitats

What is the influence of salt tectonics on the evolution of sedimentary basins and how can we reconstruct such salt features? Michael Warsitzka, PhD student at the Friedrich Schiller University of Jena, explains which complementary methods he uses to better understand salt structures and their relation to sedimentary basins. Enjoy!   Reconstruction of salt tectonic features from analogue mode ...[Read More]
