By Jack Wilkin. One of the techniques used to examine fossils in the laboratory is photography with the aid of UV light. Ultraviolet light causes minerals in the fossils to fluoresce creating a clearer contrast between the fossil and the surrounding matrix. Ultraviolet photography is a cost-effective laboratory technique that can be readily applied to a wide range of strata types and taxonomic gro ...[Read More]

Chasing solar storms as an early career scientist
Hello! My name is Erika Palmerio and I am a newly qualified Dr in space physics from the University of Helsinki, Finland. In this blog post I will talk about my PhD research and my future career plans. The title of my PhD dissertation is “Magnetic structure and geoeffectiveness of coronal mass ejections”. Coronal mass ejections (or CMEs) are huge and spectacular clouds of magnetic field and plasma ...[Read More]

Architecture and sediments, heritage and future
As geoscientists in Europe, we should consider ourselves to be very lucky to have a rich architectural heritage. The first insights we gain about the geology of an area can be read in beautiful historic buildings. For centuries, construction and architecture have been driven by two constraints: adapt to the local environment, and use locally available materials. Heritage buildings thus represent v ...[Read More]

GeoTalk: Introducing EGU’s new Head of Media, Communications and Outreach
GeoTalk interviews usually feature the work of early career researchers, but this month we deviate from the standard format to speak to the newest member of the EGU office, Terri Cook. Terri is an award-winning science and travel writer who has a passion for geology and storytelling. You can find her work featured in a number of news outlets, including Scientific American, New Scientist, Eos, Lone ...[Read More]

Did you know… about the fluctuating past of north-east Greenland?
Recent geological data shows that during a very cold phase of our Earth’s climate (between 40,000 and 26,000 years ago), there was a huge expansion of polar ice sheets, yet the north-eastern part of the Greenland ice sheet was less extensive than today. How could this have occurred? In this post we shed light on the potential causes of this ice sheet behaviour. What do we know about present- ...[Read More]

For Dummies – How do wildfires impact permafrost? [OR.. a story of ice and fire]
![For Dummies – How do wildfires impact permafrost? [OR.. a story of ice and fire]](https://blogs.egu.eu/divisions/cr/wp-content/blogs.dir/17/files/2019/10/DJI01011-700x400.jpg)
Wildfire – like the ones observed in the Northwest Territories, Canada in 2014 (Fig. 1) – is a natural part of permafrost landscapes, but fires are expected to get more frequent and severe as the climate warms. This could accelerate the degradation of permafrost, with negative consequences on the local and global scale! We have a pretty good understanding of how permafrost responds to fire t ...[Read More]

The bad, the good and the unpredictable: living with volcanoes / part 1
Introduction Humans have existed and lived alongside volcanoes for as long as we have been on the planet. For some, this has been beneficial and often, in fact, we can see how indigenous knowledge finds a sustainable approach living with them. However, in some cases, societies cannot cope and are overwhelmed with volcanic eruptions. There are many examples from archaeological studies dealing with ...[Read More]

How can remote sensing and wavelet transform unravel natural and anthropogenic ground motion processes?
Underground energy storage and gas storage in aquifers In the context of energy transition, massive energy storage is a key issue for the integration of renewable sources into the energy mix. Storing energy in the underground can lead to larger-scale, longer-term and safer solutions than above-ground energy storage technologies. In particular, natural gas storages are designed to address different ...[Read More]

Climate protests at the start of Global Week for Future
For months, students have skipped school on Fridays to ask for more action against climate change. To kick off the Global Week for Future, last Friday saw thousands of demonstrations in many countries around the globe, with not only high school students joining the fray, but people from all walks of life. GFZ Potsdam’s Bernhard Steinberger and Thilo Wrona share their experiences in Potsdam and Ber ...[Read More]
