Do you need support from the EGU to organise a training school or a conference in the Earth, planetary or space sciences? Up until 15 August 2019, we welcome applications from EGU members interested in organising an Angioletta Coradini Conference, a Mary Anning Conference or an Alexander von Humboldt Conference. To apply, please check the conference series benefits and requirements page before submitting your proposal. We also welcome proposals for training schools scheduled for 2020.
The EGU Geoscience Days are events organised around Europe that aim to raise awareness of the Earth, planetary and space sciences to students, researchers, the wider public and national policymakers. The first event will take place in Bucharest, Romania, on 31 May 2019.
The EGU election for the role of President of the Soil System Sciences (SSS) Division was open for votes from all 2019 EGU members affiliated with the division from 9 April until 14 April 2019. Claudio Zaccone was elected as SSS Division President for a two-year term (2019–2021) starting today. He may stand for re-election for a further two years at the EGU Autumn Election 2019. Thank you to all EGU members who used their voting right and to the candidates!
Volatile organic compound (VOC) emissions influence air quality and particulate distributions, particularly in major source regions such as the Amazon. A sampler for collecting VOCs from an unmanned aerial vehicle (UAV) is described. Field tests of its performance and an initial example data set collected in the Amazon are also presented. The low cost, ease of use, and maneuverability of UAVs give this method the potential to significantly advance knowledge of the spatial distribution of VOCs.
The work addresses the need for reliable precipitation forecasts in hyper-arid environments through state-of-the-art hydro-meteorological modeling. Accounting for land–atmosphere interactions in the applied model is shown to improve the accuracy of precipitation output. The chain of events controlling the soil moisture–precipitation feedback are diagnosed and verified by in situ observations and satellite data.
We use 2010–2015 satellite observations of atmospheric methane to improve estimates of methane emissions and their trends, as well as the concentration and trend of tropospheric OH (hydroxyl radical, methane’s main sink). We find overestimates of Chinese coal and Middle East oil/gas emissions in the prior estimate. The 2010–2015 growth in methane is attributed to an increase in emissions from India, China, and areas with large tropical wetlands. The contribution from OH is small in comparison.
To elucidate the potential effects of crushed nodule particle deposition on abyssal meiobenthos, we covered abyssal soft sediment in the Peru Basin (4200 m depth) with approximately 2 cm of this nodule material for 11 d. About half of the meiobenthos migrated from the sediment into the added material, and nematode feeding type proportions in that added layer were altered. These results considerably contribute to our understanding of the short-term responses of deep-sea meiobenthos to burial.
The mysterious appearance and disappearance of the Weddell Polynya, a giant hole in the ice, has long puzzled scientists. Recent work reveals that it is tightly tied to energetic storms. Read on to find out more… The eastern side of the Weddell Sea is a region known for its low concentration of sea ice due to the presence of a seamount, an underwater plateau called the Maud Rise. The seamount influences ocean circulation by bringing warm water closer to the …
Every week, The Sassy Scientist answers a question on geodynamics, related topics, academic life, the universe or anything in between with a healthy dose of sarcasm. Do you have a question for The Sassy Scientist? Submit your question here. Meghan asks: Why is your research relevant? Dear Meghan, Because I like it. My supervisor is in my office every day to talk about my results. I talk to people outside my department and they say it all looks very promising. …
