In 1821, peat cutters discovered a body similar to a mummy, pinned down by two wooden stakes deep in the mud. The body’s face still held red hair and a beard, their teeth were well preserved, and a hoop of willow was wrapped around their throat. But this wasn’t the dry, hot climate of Egypt but a cold and rain-sodden bog of Ireland. Later assessment suggested that these were the remain ...[Read More]

Hydrological soundscapes: listening to hydrological regimes
It is common to hear that a good illustration is better than a lengthy textual explanation, and we fully agree with that statement. We are used to retrieving information and understanding things through visual illustrations. In the scientific community, any paper comes with a number of plots to show the data, and diagrams to explain concepts, ideas or workflows. For example, a typical plot that hy ...[Read More]

GeoRoundup: the highlights of EGU Journals published during January!
Each month we feature specific Divisions of EGU and during the monthly GeoRoundup we put the journals that publish science from those Divisions at the top of the Highlights roundup. For January, the Divisions we are featuring are: Earth and Space Science Informatics (ESSI), Planetary and Solar System Sciences (PS) and Solar-Terrestrial Sciences (ST). They are served by the journals: Annales Geophy ...[Read More]

Imaggeo On Monday: Blue cements in Jurassic rocks?
Staining of thin sections and rock slabs is a method of identification that has long helped researchers to distinguish certain minerals which often otherwise appeared very similar. Modern studies have now largely replaced this method of identification with more analytical techniques that usually provide a higher degree of certainty, such as analysis with a microprobe or Scanning Electron Microscop ...[Read More]

Earthquake Watch: The Guanshan, Chih-shang sequence in Taiwan, 17-18 Sept, 2022
Contribution about the September 2022 M 6.6 and M 6.8 earthquakes in South-East Taiwan Dr.Yifan Yin , recent graduate at the Swiss Seismological Service (SED) at the Earth Sciences department of ETH Zürich. On 17 September 2022, a magnitude 6.6 quake shook the southern-east Taiwan. The merely 8.6 km deep quake was widely felt across the island. Sixteen hours later, a magnitude 6.8 shallow quake fo ...[Read More]

GeoTalk: meet Martin Archer, Space Physicist and Outreach expert!
Hi Martin. Thank you for joining me for this interview! To start, could you please tell our readers a bit about yourself and your research interests? I’m a space plasma physicist at Imperial College London, studying how the interaction between the solar wind and our magnetosphere leads to a huge amount of dynamics and waves that play a role in space weather. I’m also the Chair of EGU’s Outreach Co ...[Read More]

Image of the week – The gaze of the ice cap
We are getting used to perceiving glaciers more and more distant and disconnected from our mountains. With each passing year, it is more difficult to observe them, reach them or climb them. They are becoming an exotic element of the Alpine imagination. When our gaze rests on a mountain glacier, with its crevasses and large moraines, we are filled with the fascination of someone observing a new nat ...[Read More]

The impacts of space weather on the mid-latitude upper atmosphere
The upper atmosphere of Earth is constantly being impacted by the flow of charged particles being released from the sun. This flow (the solar wind) carries with it a magnetic field which distorts and reshapes that of Earth, ultimately resulting in a large amount of electromagnetic space weather energy being channelled into the polar regions. One of the most frequently observed outcomes of this pro ...[Read More]

Climate Tipping Points through the “eyes” of the Masters: a virtual art exhibition
We are running out of time in fighting the effects of climate change. With the greenhouse gasses emissions steady, the planet is reaching warming levels that could cause some large ecosystems to tip in different states. A tipping point in the climate system refers to a threshold beyond which a small change in a particular variable can cause a significant and potentially irreversible change in the ...[Read More]
