Event: Digitalization and Climate Change

At the Matchpoint Conference on 27-29 May, Christoffer Karoff from Geoscience is the host at a talk about digitalization and climate change. One challenge is that the green transition is impossible without digital technologies, but at the same time, the IT sector is also one of the greatest contributors to global CO2 emissions. Sign up by May 20th.

PORO-CLIM will map the seabed in the Atlantic Ocean

On board the ship Celtic Explorer, Per Trinhammer will for the next 4 weeks together with researchers and engineers from Danish, British and Irish universities map the seabed in the Atlantic Ocean under Porcupine and Rockall basins. They look at how the Earth's deep interior has affected the global climate in the geological past. Follow them here.

New article on the impact of flood irrigation on the water cycle

More than 60% of the applied water in flood irrigation can slowly return back to the riparian zones and streams with delays that can be more than a month. This 'temporary storage' of water is an important component of the water cycle. This can be seen in models that Niels Claes has made with partners from the University of Wyoming.

New insight into the Viking Age craft production in Ribe

For the first time, a research project has explored the metal crafts of the Viking Age by following the entire production chain with geochemical analysis methods. The analyses were done by Vana Orfanou during her postdoc here at Geoscience and are the results of an interdisciplinary collaboration between Geoscience, Sydvestjyske Museer and UrbNet.

The caldera wall by Balo's harbour on Thera

Article brings new light on the Santorini volcano

Walter L. Friedrich, J. Richard Wilson, Annette Højen Sørensen and Samson Katsipis discuss and reinterpret the stratigraphy of the caldera. Via geological and archaeological finds under the ash layer of the caldera wall from the Minoan eruption, they conclude that terraces existed on the inside of the caldera, which was inhabited in the Bronze Age.

Gender diversity in Danish geoscience

2021.04.15 | Department of Geoscience, Staff

Project initiated to achieve gender balance

The long-term perspective of the project is to achieve an equal gender distribution and thus prevent a massive loss of talent and create an attractive workplace. The project collects gender-based data, which must be discussed in relation to foreign studies and experiences regarding gender-based initiatives in research environments.

New study on the oceanic conditions of the last glacial period

Professor Marit-Solveig Seidenkrantz and assistant professor Christof Pearce show in the study that there was a stronger influx of Atlantic Water into the Labrador Sea region than today during the Last Glacial Maximum (23-19,000 years ago), suggesting a much more vigorous North Atlantic Ocean circulation than previously assumed.

Goodbye to Delphini-1

On Sunday 14 March 2021, the student satellite Delphini-1 from Aarhus University burned up in the atmosphere after a long period of faithful service. The satellite stayed up for quite a bit longer than expected. The project has been a great success with many involved from various Departments at Aarhus University, including Geoscience. Read more.

New studies support that agricultural lime affects strontium analyzes

Erik Thomsen and Rasmus Andreasen from the Department of Geoscience demonstrate in two new scientific articles that strontium from agricultural lime is leached from the upper soil layers and thus affects the strontium isotope values in the environment. Thus, a number of hypotheses about the origins of prehistoric humans should be revised.
