Research Software Engineers from the Geosciences assemble for the first time at EGU General Assembly 2018
On April 12th 2018, the first Research Software Engineers (RSEs) for geosciences meeting was held at the European Geophysical Union (EGU) General Assembly (GA) in Vienna, Austria. The EGU GA is a huge event with over 15.000 people from more than 100 countries. It has a diverse programme with thousands of posters and hundreds of sessions, but what it lacked was an event to bring together scientists ...[Read More]
Climate: Past, Present & Future
How glowing sediment can help to decipher the Earth’s past climate !
The last 2.5 Million years of the Earth’s history (termed Quaternary) are characterised by climatic cycles oscillating between warm (interglacial) and cold (glacial) periods. To be able to fully understand and interpret past climate variations the development of accurate and precise chronological techniques is crucial. Optically stimulated luminescence (OSL) dating is a strong geochronological too ...[Read More]

Imaggeo on Mondays: Bristlecone pines, some of Earth’s oldest living life forms
About 5,000 years ago, the ancient city Troy was founded, Stonehenge was under construction, and in the rugged Sierra Nevada mountain range, groves of bristlecone pine seedlings began to take root. Many of these pines are still alive today, making them the world’s oldest known living non-clonal life forms. Raphael Knevels, a PhD student from the Friedrich-Schiller-University’s Department of Geogra ...[Read More]

The microworld of the past
In my last blog, I described the diverse world of pollen and how palynology – the study pollen, is used in geosciences. Today, I turn to another microcosmos: that of finest layers deposited at the bottom of a lake. A large majority of geoscientists would tell you the best part of their job is field work. Despite sometimes harsh weather conditions, long hikes in wind, rain or merciless sun, many ge ...[Read More]

The perfect ice floe
Current position: 89°31.85 N, 62°0.45 E, drifting with a multi-year ice floe (24th August 2018) With a little more than three weeks into the Arctic Ocean 2018 Expedition, the team has found the right ice floe and settled down to routine operations. Finding the perfect ice floe for an interdisciplinary science cruise is not an easy task. The Arctic Ocean 2018 Expedition aims to understand the linka ...[Read More]

Bridging the gap between science and decision makers – a new tool for nuclear emergencies affecting food and agriculture
The International Atomic Energy Agency (IAEA) has developed an online system to assist in improving the response capabilities of authorities in the event of an emergency caused by natural hazards. This tool provides a clear overview of radioactive contamination of crops and agricultural lands through improved data management and visualization, it also assists in decision support processes by sugge ...[Read More]

Imaggeo on Mondays: Antarctic winds make honeycomb ice
These delicate ice structures may look like frozen honeycombs from another world, but the crystalline patterns can be found 80 degrees south, in Antarctica, where they are shaped by the white continent’s windy conditions. In Western Antarctica is a 9-kilometre line of rocky ridges, called Patriot Hills. Often cold wind furiously descends from the hills across Horseshoe Valley glacier, sculpting do ...[Read More]

Lombok and Fiji – or why a M6.9 earthquake can be worse news than a M8.2 event
Two magnitude 6.9 earthquakes in Indonesia in the space of two weeks, 20 km apart. Meanwhile, a magnitude 8.2 event in the Pacific. Did you get any questions about the end of the world being upon us, how come all these quakes happen so close together and why the Fiji event was so harmless?

An overnight train view of China’s Anthropocene – Part 2
Science fiction is no match for industrial non-stop China. Electric bikes zip across the cities of Shanghai and Beijing, and soundtrack the neon nights with their passing whirr. Here, some kind of two-wheeled revolution has taken place which are we completely unaware of in the West. It’s Blade Runner meets Total Recall in a future which has already come to pass. The very existence of our ele ...[Read More]
