Apply to be an EGU division early career scientist representative

  • EGU news
  • 1 February 2018

Early career scientists (ECS) make up a significant proportion of the EGU membership and it’s important to us that your voices get heard. To make sure that happens, each division appoints an ECS representative: the vital link between the Union and the ECS membership. This year a number of divisions are looking for new representatives. Follow the link to find out more, including how to get involved.

  • 16 January 2018

The European Geosciences Union (EGU) has named journalists Julia Rosen and Vivien Cumming as the winners of its 2018 Science Journalism Fellowship. The support will allow Rosen to travel to the UK to write about the role of soil in the phosphorus crisis, while Cumming will follow scientists in Myanmar to tell the story of carbon in rivers.

Decoupling of dissolved organic matter patterns between stream and riparian groundwater in a headwater forested catchment

Streams are important sources of carbon to the atmosphere, though knowing whether they merely outgas terrestrially derived carbon dioxide or mineralize terrestrial inputs of dissolved organic matter (DOM) is still a big challenge in ecology. Our study highlights that stream DOM is not merely a reflection of riparian groundwater entering the stream and that headwater streams have the capacity to internally produce, transform, and consume DOM.


Ideas and perspectives: hydrothermally driven redistribution and sequestration of early Archaean biomass – the “hydrothermal pump hypothesis”

The origin of organic matter in the oldest rocks on Earth is commonly ambiguous (biotic vs. abiotic). This problem culminates in the case of hydrothermal chert veins that contain abundant organic matter. Here we demonstrate a microbial origin of kerogen embedded in a 3.5 Gyr old hydrothermal chert vein. We explain this finding with the large-scale redistribution of biomass by hydrothermal fluids, emphasizing the interplay between biological and abiological processes on the early Earth.


A systemic approach for modeling soil functions

This paper deals with the importance of soil for our terrestrial environment and the need to predict the impact of soil management on the multitude of functions that soil provides. We suggest to consider soil as a self-organized complex system and provide a concept of how this could be achieved. This includes how soil research, currently fragmented into a number of more or less disjunct disciplines, may be integrated to substantially contribute to a science-based evaluation of soil functions.

Thermodynamics of saline and fresh water mixing in estuaries

This paper presents a new equation for the dispersion of salinity in alluvial estuaries based on the maximum power concept. The new equation is physically based and replaces previous empirical equations. It is very useful for application in practice because in contrast to previous methods it no longer requires a calibration parameter, turning the method into a predictive method. The paper presents successful applications in more than 23 estuaries in different parts of the world.

Cosmic rays - messengers from space

Cosmic rays - messengers from space

Cosmic rays (CRs), are not actually rays, but highly energetic charged particles of extraterrestrial origin. The life cycle of a cosmic ray particle starts with its birth at some point in the Universe, its travel at nearly the speed of light and finally with its death ( e.g. at a detector). These highly energetic particles strike our planet from all directions and thus provide a constant background. In practice, this means that thousands of cosmic ray particles pass through our …

Imaggeo on Mondays: The Crossroads of Flood and Drought

Imaggeo on Mondays: The Crossroads of Flood and Drought

This picture was taken on the way back from collecting field measurements at the Lordsburg Playa in southwestern New Mexico, USA. The setting sun highlights the contrast between the dry, cracked soil and the standing water from antecedent rainfall. A playa is a flat topographic depression in arid or semi-arid regions that contains a large amount of deposited sediment. When the surface of the playa is dry, this deposited sediment is exposed and at risk of being entrained into the …

What is coming at the next EGU’s General Assembly?

The next EGU’s General Assembly is taking place in three weeks! We bet you already started planning your program for the week, and that Natural Hazard (NH) sessions are included, and, especially if you are an Early Career Scientist, you have found many sessions and courses targeting your specific needs and interests. What fits more to your interests: Attend talks and posters, learn and improve skills, or take an active role in a serious game? Or maybe all of them? …
