The EGU is now accepting proposals for Galileo Conferences, which aim to address well-focused cutting-edge topics at the frontier of geosciences research. The conferences are informal: the state-of-the-art is outlined in keynote talks designed to trigger in-depth discussion of important aspects of the conference topic. EGU members can propose to organise a Galileo Conference and apply for funding by the end of February 2019.
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 results of the EGU elections are now available on the elections page of this website. Patric Jacobs was elected as the EGU Treasurer for the term 2019–2021. He will be inaugurated during the EGU plenary meeting on 8 April 2019 in Vienna, Austria.
Copernicus Publications, who manage EGU publications, are rolling out new updates for EGU journals aimed at improving the user experience, particularly for those accessing the journal websites on a mobile device. ESurf, TC and CP have now published their first papers in full-text html, with other EGU journals following suit over the next few weeks. The HTML format makes it easier for search engines to find content on EGU journals. Importantly, it also means papers can easily be read on mobile devices since the content of the websites is responsive, adapting to the size of the screen.
The impact of desert dust on cloud formation is investigated for a major Saharan dust event over Europe by interactive regional dust modeling. Dust particles are very efficient ice-nucleating particles promoting the formation of ice crystals in clouds. The simulations show that the observed extensive cirrus development was likely related to the above-average dust load. The interactive dust–cloud feedback in the model significantly improves the agreement with aircraft and satellite observations.
Thwaites Glacier, West Antarctica, has experienced rapid grounding line retreat and mass loss in the past decades. In this study, we simulate the evolution of Thwaites Glacier over the next century using different model configurations. Overall, we estimate a 5 mm contribution to global sea level rise from Thwaites Glacier in the next 30 years. However, a 300% uncertainty is found over the next 100 years, ranging from 14 to 42 mm, depending on the model setup.
This paper provides an overview of a coordinated international experiment to determine the strengths and weaknesses in how climate models treat snow. The models will be assessed at point locations using high-quality reference measurements and globally using satellite-derived datasets. How well climate models simulate snow-related processes is important because changing snow cover is an important part of the global climate system and provides an important freshwater resource for human use.
The 4.2 ka eventbetween 4.2 and 3.9 ka has been widely discussed in the Northern Hemsiphere but less reported in the Southern Hemisphere. Here, we use speleothem records from Rodrigues in the southwestern Indian Ocean spanning from 6000 to 3000 years ago to investigate the regional hydro-climatic variability. Our records show no evidence for an unusual climate anomaly between 4.2 and 3.9 ka. Instead, it shows a multi-centennial drought between 3.9 and 3.5 ka.
During the upper Carboniferous period (Namurian, Westfalian and Stephanian) large areas of central western Germany were covered by coastal swamp forests dominated by Lepidodendron und Sigillaria. Periodic marine and fluvial transgressions caused the swamps being regularly buried by siliciclastic material, resulting in up to 5500 m thick successions of alternating organic-rich and clastic-rich sedimentary rock. The organic-rich packages were later subject to coalification producing up to 100 individual coal beds in the area of the river Ruhr. Presumably, initial (private) …
This photo depicts the famous ash cloud of the Icelandic volcano Eyjafjallajökull, which disrupted air traffic in Europe and over the North Atlantic Ocean for several days in spring 2010. The picture was taken during the initial phase of the eruption south of the town of Kirjubæjarklaustur, at the end of a long field work day. Visibility inside the ash cloud was within only a few metres. The eruption was preceded by years of seismic unrest and repeated magma intrusions. …
On September 15th, 2018, at 18:02 local time, NASA launched its newest satellite – the second generation Ice, Cloud and land Elevation Satellite (ICESat-2). ICESat-2 only contains one instrument – a space laser that fires 10,000 pulses per second to Earth to measure elevation. Its primary purpose is for monitoring the ever changing cryosphere, so naturally there are plenty of ice enthusiasts that are excited for the data it will provide! Space laser? The space laser is referred to more …
