Boreal forest fire in Canada

Air pollution in New York City linked to wildfires hundreds of miles away

  • Press release
  • 21 January 2020

A new study published in the European Geosciences Union (EGU) journal Atmospheric Chemistry and Physics shows that air pollutants from the smoke of fires from as far as Canada and the southeastern U.S. traveled hundreds of miles and several days to reach Connecticut and New York City, where it caused significant increases in pollution concentrations.

Fukushima: lessons learnt from an extraordinary case of soil decontamination

  • Press release
  • 12 December 2019

Following the accident at the Fukushima nuclear power plant in Japan, in March 2011, the Japanese authorities decided to carry out major decontamination works in the affected area, which covers more than 9,000 km2. On December 12, 2019, with most of this work having been completed, the scientific journal SOIL of the European Geosciences Union (EGU) is publishing a synthesis of approximately sixty scientific publications that together provide an overview of the decontamination strategies used and their effectiveness, with a focus on radiocesium.

Machine learning and soil sciences: a review aided by machine learning tools

The application of machine learning (ML) has shown an accelerated adoption in soil sciences. It is a difficult task to manually review all papers on the application of ML. This paper aims to provide a review of the application of ML aided by topic modelling in order to find patterns in a large collection of publications. The objective is to gain insight into the applications and to discuss research gaps. We found 12 main topics and that ML methods usually perform better than traditional ones.

A new look at the environmental conditions favorable to secondary ice production

This study attempts identification of mechanisms of secondary ice production (SIP) based on the observation of small faceted ice crystals. It was found that in both mesoscale convective systems and frontal clouds, SIP was observed right above the melting layer and extended to the higher altitudes with colder temperatures. A principal conclusion of this work is that the freezing drop shattering mechanism is plausibly accounting for the measured ice concentrations in the observed condition.

Global catchment modelling using World-Wide HYPE (WWH), open data, andstepwise parameter estimation

How far can we reach in predicting river flow globally, using integrated catchment modelling and open global data? For the first time, a catchment model was applied world-wide, covering the entire globe with a relatively high resolution. The results show that stepwise calibration provided better performance than traditional modelling of the globe. The study highlights that open data and models are crucial to advance hydrological sciences by sharing knowledge and enabling transparent evaluation.

Mapping the drivers of uncertainty in atmospheric selenium deposition with global sensitivity analysis

The amount of the micronutrient selenium in food largely depends on the amount and form of selenium in soil. The atmosphere acts as a source of selenium to soils through deposition, yet little information is available about atmospheric selenium cycling. Therefore, we built the first global atmospheric selenium model. Through sensitivity and uncertainty analysis we determine that selenium can be transported thousands of kilometers and that measurements of selenium emissions should be prioritized.

Imaggeo on Mondays: The sun rises also in the middle of nowhere

Imaggeo on Mondays: The sun rises also in the middle of nowhere

Uluru in Australia is one of the most visibly recognisable geological features in the world. This sandstone formation covers an area of 3.3 kilometres and stands 345 metres above the plains around it. Deposited in an inland sea during the Cambrian Period approximately 500 million years ago, the arkose sandstones were uplifted and folded during the Alice Springs Orogeny, between 400 and 300 million years ago, making the formation more resistant to later erosion. Because Uluru is in the middle …

Early Career Scientist representative? You might be the next one!

Why Early Career Scientist (ECS) representatives? The EGU SM division tackles cutting-edge research topics covering a large variety of basic and applied scientific fields in the context of both natural resources and natural hazards. The EGU SM division is a space where one can discuss a wide range of scientific questions and their societal impact. To engage in a forward-looking discussion and strengthen the collaborations within its community, early career scientists are essential. The role of these representatives is to …

An interview with Jean Holloway on the importance of mental health in graduate school

An interview with Jean Holloway on the importance of mental health in graduate school

Recent studies have shown that mental health conditions are far more common in graduate students than in the general public (e.g. Bolotnyy et al., 2020). Despite the prevalence, these issues are not something that are often openly discussed, and graduate students often don’t seek treatment. This week, we are interviewing Jean Holloway who aims to shed some light on her personal experience with some of these issues. Jean is a Ph.D. student at the University of Ottawa in Ottawa, Canada, …
