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.
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.
The EGU is Europe’s premier geosciences union, dedicated to the pursuit of excellence in the Earth, planetary, and space sciences for the benefit of humanity, worldwide. Membership is open to individuals who subscribe to the objectives of the EGU and who are professionally engaged in or associated with either the geosciences, planetary and space sciences, or related studies. Membership is affordable and provides a number of benefits.
The EGU 2018 General Assembly (8–13 April, Vienna, Austria) will bring together geoscientists from all over the world to one meeting covering all disciplines of the Earth, planetary and space sciences.
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.
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.
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.
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.
The EGU General Assembly 2018 programme is available here. Take a look and – if you haven’t already – register for the conference by 1 March to make the early registration rates! 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 …
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 …
For today blog, we have interviewed Clemens Eisank about OBIA and its application in Natural Hazard. Dr. Clemens Eisank is Remote Sensing Specialist & Project Manager at GRID-IT Company in Innsbruck (Austria). He obtained his Ph.D. from the Department of Geoinformatics – Z_GIS at Salzburg University in 2013. In his Ph.D. research, he proposed a workflow for automated geomorphological mapping with object-based image analysis (OBIA) methods. His research interests include remote sensing based mapping/monitoring of natural hazards and the development/automation …
