The 2020 General Assembly of the European Geosciences Union (EGU) provides an opportunity for journalists to find out about the latest research in the Earth, planetary and space sciences and to talk to researchers from all over the world. The meeting, the largest geosciences conference in Europe, is anticipated to bring together more than 15,000 scientists. It runs from 3 to 8 May at the Austria Center Vienna, in Vienna, Austria.
The EGU is Europe’s premier geosciences union, dedicated to the pursuit of excellence in the Earth, planetary, and space sciences for the benefit of humanity, worldwide. Membership is open to individuals who subscribe to the objectives of the EGU and who are professionally engaged in or associated with either the geosciences, planetary and space sciences, or related studies. Membership is affordable and provides a number of benefits, including eligibility to present your research at the annual EGU General Assembly and substantially reduced registrations rates to the meeting.
The EGU invites applications to provide feedback on how the organisation can best support university-level geoscience teaching on 6 April 2020 in Vienna.
The full results of the Union’s autumn 2019 election are now available.
We propose a new exploration of the concept of “spontaneous” lithospheric collapse at a transform fault (TF) by performing a large study of conditions allowing instability of the thicker plate using 2-D thermomechanical simulations. Spontaneous subduction is modelled only if extreme mechanical conditions are assumed. We conclude that spontaneous collapse of the thick older plate at a TF evolving into mature subduction is an unlikely process of subduction initiation at modern Earth conditions.
Terrestrial ion transport and total escape are synthesized, with stress on the high-latitude polar region and the inner magnetosphere where Custer significantly improved knowledge. After estimating the outflow flux and destinations, complicated ion dynamics in the inner magnetosphere was classified and summarized, through which more than half the O+ is finally lost to space. Together with direct escapes, total O+ escape is high enough to influence the evolution of the biosphere.
Perhaps the oldest question in hydrology is “Where does water go when it rains?”. Here we present a new way to measure how the terrestrial water cycle partitions precipitation into its two ultimate fates: “green water” that is evaporated or transpired back to the atmosphere and “blue water” that is discharged to stream channels. Our analysis may help in gauging the vulnerability of both water resources and terrestrial ecosystems to changes in rainfall patterns.
The western USA is frequently affected by multiannual summer droughts. They can be separated into two groups with distinct spatial patterns. This study analyzes the atmospheric circulation during multiannual droughts in a new 3-D climate reconstruction. We confirm two distinct drought types differing with respect to atmospheric circulation as well as sea surface temperatures. Our results suggest that both the Pacific and the extratropical North Atlantic region affect North American droughts.
2019 was a brilliant year for our blogging network here at EGU. Across the EGU’s official blog, GeoLog, as well as the network and division blogs there were so many interesting, educational and just downright entertaining posts this year it was hard to get the blog editors to choose their favourites! Nevertheless in December, to celebrate the excellent display of science writing across the network and division blogs, we launched the EGU Blogs competition. From a shortlist of posts selected …
The Karthaus summer school on Glaciers and Ice Sheets in the Climate System has a long history of training many generations of PhD students, thus forming professional networks that have lasted throughout their careers. The Karthaus summer school has been described in detail in a previous Cryoblog post. Here we want to focus on the story of a glacier… Hochjochferner, a retreating glacier One of the highlights during each summer school is a one-day excursion to the Hochjochferner (Figure 1), …
If you are pre-registered for the 2020 General Assembly (Vienna, 3 – 8 May), you can take part in our annual photo competition! Winners receive a free registration to next year’s General Assembly! The eleventh annual EGU photo competition opened on 15 January. Up until 15 February, every participant pre-registered for the General Assembly can submit up to three original photos and one moving image on any broad theme related to the Earth, planetary, and space sciences. Shortlisted photos will …
