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.


Julia Rosen and Vivien Cumming, winners of the EGU 2018 Science Journalism Fellowship

Julia Rosen and Vivien Cumming awarded EGU Science Journalism Fellowship

  • Press release
  • 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.

Long-term series and trends in surface solar radiation in Athens, Greece

The National Observatory of Athens has been collecting solar radiation, sunshine duration, and cloud and visibility data/observations since the beginning of the 20th century. In this work we present surface solar radiation data since 1953 and reconstructed data since 1900. We have attempted to show and discuss the long-term changes in solar surface radiation over Athens, Greece, using these unique datasets.

Total ozone trends from 1979 to 2016 derived from five merged observational datasets – the emergence into ozone recovery

This paper commemorates the 30-year anniversary of the initial signing of the Montreal Protocol (MP) on substances that deplete the ozone layer. The MP is so far successful in reducing ozone-depleting substances, and total ozone decline was successfully stopped by the late 1990s. Total ozone levels have been mostly stable since then. In some regions, barely significant upward trends are observed that suggest an emergence into the expected ozone recovery phase.

Satellite remote sensing reveals a positive impact of living oyster reefs on microalgal biofilm development

Using satellite technology and a life-size experiment, we analysed the impact of oyster reefs on mats of microscopic algae that develop within coastal mudflats. We showed that the relationship between microalgae and oysters is not limited to a one-way process where microalgae are a food source to oysters, but that oysters also promote microalgae mats development, presumably by providing nutrients to them. This might yield new insights into coastal ecosystem management.

Evidence for a continuous decline in lower stratospheric ozone offsetting ozone layer recovery

Using a robust analysis, with artefact-corrected ozone data, we confirm upper stratospheric ozone is recovering following the Montreal Protocol, but that lower stratospheric ozone (50° S–50° N) has continued to decrease since 1998, and the ozone layer as a whole (60° S–60° N) may be lower today than in 1998. No change in total column ozone may be due to increasing tropospheric ozone. State-of-the-art models do not reproduce lower stratospheric ozone decreases.

Image of the Week – The world in a grain of cryoconite

Microbes growing on glaciers are recognized for their importance in accelerating glacier melting by darkening their surface and for maintaining biogeochemical cycles in Earth’s largest freshwater ecosystem. However, the microbial biodiversity of glaciers remains mysterious. Today, new DNA sequencing techniques are helping to reveal glaciers as icy hotspots of biodiversity. To see a world in a grain of…cryoconite Earth’s glaciers and ice sheets are among its most impressive features, yet this majesty conceals their microscopic riches. We must turn to …

This year’s scientific programme of the General Assemby includes Union-wide Sessions, such as the medal lectures, great debates, short courses, education and outreach symposia, as well as townhall and splinter meetings, just to name a few. The Disciplinary Sessions and Interdisciplinary Events, encompass the oral, poster and PICO …


From groundwater flow to groundwater glow: why does groundwater fluoresce in ultraviolet light?

From groundwater flow to groundwater glow: why does groundwater fluoresce in ultraviolet light?

Post by Andy Baker, Professor researching groundwater, caves, past climate, organic carbon and more at the University of New South Wales, in Australia. __________________________________________________ We often come across items that glow after being exposed to ultraviolet light. Fluorescent stickers can be bought for the ceilings of bedrooms; fluorescent hands on analogue clocks and watches; fluorescent markings on a car dashboard. In all these examples, there are organic molecules that absorb energy in the form of ultra-violet light and can then …
