The EGU Outreach Committee has named three Public Engagement Grant winners this year: a project empowering school children to create their own environmental change maps, a model to explain how geophysics is done under the ocean and an investigative geoscience podcast !
This November EGU will co-host an hybrid discussion of how the geosciences can support the EU’s biodiversity targets, addressing specific issues relating to the Nature Restoration Law and exploring ways that greater collaboration can be achieved between these communities.
Conference of the European Geosciences Union (EGU) at the Max Planck Institute for Chemistry to further develop and promote interactive open access publishing with transparent peer review and public discussion
EGU has awarded funding to four science journalists to cover particular geoscience stories of interest over the next 12 months. The funding has been awarded to Ayesha Tandon, Tim Kalvelage, Panos Tsimpoukis and Kerstin Hoppenhaus (with associate Sibylle Grunze).
Ice shelves in the Amundsen Sea are thinning rapidly as ocean currents bring warm water into cavities beneath the floating ice. We use 2-year-long mooring records and 16-year-long model simulations to describe the hydrography and circulation near the ice front between Siple and Carney Islands. We find that temperatures here are lower than at neighbouring ice fronts and that the transport of heat toward the cavity is governed by wind stress over the Amundsen Sea continental shelf.
Some 155 million years ago, sediments were deposited in a shallow subtropical sea. Coral reefs formed in a warm and arid climate during high sea level, and clays were washed into the ocean at low sea level and when it rained. Climate and sea level changes were induced by cyclical insolation changes. Analysing the sedimentary record, it appears that sea level rise today (as a result of global warming) is more than 10 times faster than the fastest rise reconstructed from the geologic past.
Identifying drought legacy effects is challenging because they are superimposed on variability driven by climate conditions in the recovery period. We develop a residual-based approach to quantify legacies on gross primary productivity (GPP) from eddy covariance data. The GPP reduction due to legacy effects is comparable to the concurrent effects at two sites in Germany, which reveals the importance of legacy effects. Our novel methodology can be used to quantify drought legacies elsewhere.
The general assembly 2023 is approaching, and the EGU Geodesy division is looking for an enthusiastic early career scientist (ECS) to take over the role of the division ECS Co-representative. But what do you have to do as an ECS-representative? And where can you sign up? Early career scientists represent a significant share of the EGU members and attendees of the general assembly. It is therefore desirable to involve this group not only as participants, but also on the division …
reading time: 10 minutes The Tambora 1815 eruption: a brief introduction On April 10th, 1815, the Tambora volcano, located on the island of Sumbawa in Indonesia, was responsible for one of the largest eruptions in the last millennium (Stothers, 1984; Sigurdsson and Carey, 1989; Oppenheimer, 2003; Self et al., 2004; Kandlbauer et al., 2013a; Kandlbauer and Sparks, 2014). The eruption had a devastating impact both in the surrounding areas but also in much more distant areas. It is in fact …
The study of the mantle helps us in understanding the tectonic evolution of the Earth. In this week’s news and views, we have honors student Mr. Robert Marks, sharing his insights. Mr. Marks has completed this Bachelors (Hons) from the University of Wollongong. When tectonic plates collide at the surface, often the denser plate will sink down into the Earth’s mantle. These subducted slabs of oceanic lithosphere are one of the principal drivers of our planet’s evolution; They pull on …
