With a total length of about 2 km, the Surdsellir lava cave is part of the Hallmundarhraun lava field in western Iceland. The caves ceiling is partly broken in, forming entrances and windows towards the earths surface. On this day of typically Icelandic weather, meteorological conditions changed quickly between sun, clouds, rain and wind. While walking through the cave during a rain shower, the su ...[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]

Can limestone digestion by volcanoes contribute to higher atmospheric carbon dioxide levels?
By Frances Deegan and Ralf Halama Carbon – the element on everyone’s lips. Carbon is unquestionably one of the most important elements on Earth – terrestrial life is carbon-based and so are many of our energy sources. From the perspective of a human time-scale, biological and anthropogenic (caused by human activity) carbon fluxes are very important (e.g. through industrial activity and burni ...[Read More]

Cryo-adventures – Behind the scenes of cryo-fieldwork
As the Arctic is warming faster than the global average, Arctic glaciers are rapidly melting. My research is about the fate of glacial organic carbon when the ice containing it melts. To investigate these processes, I travelled to several glaciers, an activity full of challenges… and rewards! My research Glacier ice covers about 11% of Earth’s land surface, and contains within it a globally ...[Read More]

Geothermal Energy and Structural Geology?
Fieldwork is a necessity to expand the brain, to kick-start 3D thinking. Field studies with a specific application in mind have – until now – usually been geared towards hydrocarbon reservoirs. However, with the increasing use of the subsurface, for example for CO2 storage and geothermal energy, alternative field studies gain importance. Here, we will focus on geothermal energy, which is in ...[Read More]

Geosciences Column: Taking a Breath of the Wild – are geoscientists more effective than non-geoscientists in determining whether video game world landscapes are realistic?
For years, geoscientists have been both fascinated and perplexed by the beautiful (yet often inaccurate) landscapes present in several video games. But are people with a geoscientific education better at telling ‘fake’ natural features from real ones? Rolf Hut, an assistant professor at Delft University of Technology in the Netherlands, and his colleagues sought to answer this question in a new st ...[Read More]

Imaggeo on Mondays: The glacier surviving climate change
Human impacts on the climate are nowadays clearly discernible, and the changes to our climate that previously happened in geologic time scales are currently happening during the span of a human lifetime. Our planet is warming and temperature today is now more than 1°C higher than it was in the pre-industrial world and rises by about 0.15-0.2°C on average each decade. The dramatic effects of this r ...[Read More]

EGU General Assembly 2020: Apply to be our next artist in residence!
Calling all artists interested in the geosciences! For the third year in a row, the European Geosciences Union (EGU) will be providing artist in residence opportunities at its annual General Assembly. Our residency programme provides artists with an opportunity to engage with scientific research in a dynamic setting and be inspired by new scientific discoveries. Researchers, on the other hand, can ...[Read More]
