Results of the EGU Extraordinary Spring Election 2019 for SSS Division President announced

  • EGU news
  • 15 April 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!

A sampler for atmospheric volatile organic compounds by copter unmanned aerial vehicles

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.

Analysis of an extreme weather event in a hyper-arid region using WRF-Hydro coupling, station, and satellite data

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.

Global distribution of methane emissions, emission trends, and OH concentrations and trends inferred from an inversion of GOSAT satellite data for 2010–2015

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.

Responses of an abyssal meiobenthic community to short-term burial with crushed nodule particles in the south-east Pacific

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 Netherlands: In search of the oldest rocks of a muddy you yet

Technically speaking, the Netherlands isn’t really a city, even though it is the most densely populated country in the European Union and one of the most densely populated countries in the world, with 488 people/km­2. It is a delta, and for many people geology is not the first thing that springs to mind when thinking about the flat countryside. Large parts of the country have been more often below sea level than above. However, below the centuries of accumulated sand …

Imaggeo on Mondays: Foggy Bandon beach, Oregon

This picture was taken at Bandon beach, Oregon. Bandon is well-known for its memorable seascape of stacks of all shapes and sizes. These rock formations are known to geologists as ‘knockers’ and carry nicknames like ‘the Wizards hat’. They date from the Jurassic period – about 200 to 145 million years ago – and are what remains from the great mélange during tectonic subduction processes when different types of rock are exposed to the surface, and the softer sandstone and …

#mineralmonday: your weekly* dose of obscure mineralogy, every Monday** [*not guaranteed; **or possibly Tuesday-Sunday] What is it? emmonsite, Fe2Te3O9.2H2O What’s it made of? Iron (Fe), tellurium (Te), oxygen (O) and water (H2O) I think I remember tellurium from chemistry class – remind me what it is? We can more or less divide the elements into the metals and the non-metals – tellurium is one that sits in between the two groups – it’s a ‘metalloid’. It’s recently become really important …
