The northern lights, or aurora borealis, are created as charged particles interact with the Earth’s atmosphere. These electrons are part of the solar wind and as they pass through the Earth’s magnetic shield (the magnetosphere); the charged particles collide with those in our atmosphere, emitting light. In the southern hemisphere this phenomenon is known as the aurora australis, but both are caus ...[Read More]

Letting the methane genie out of the bottle
Greenhouse gas levels and globally averaged surface temperatures are both on the rise. Whilst slow increases in temperatures are not easily perceived as threatening, and might even be welcomed by some, climate change can also include fast and sudden changes. These sudden changes could have disastrous effect on not only us humans, but also life on this planet more generally. When it comes to places ...[Read More]
GeoTalk: Catharina Landström on the safe storage of nuclear waste
Following Science in Public 2013 I had the pleasure of talking to Catharina Landström about the social and technical challenges to the geological disposal of high-level radioactive waste… Could you introduce yourself and let us know what propelled you into a project looking at the issues surrounding geological disposal of radioactive waste? Specialising in Science and Technology Studies (STS ...[Read More]
Imaggeo on Mondays: Lime Pancakes
These are the Pancake Rocks of Punakaiki, on the west coast of New Zealand. They are made of limestone that was deposited as calcifying organisms fell to their fate on the sea floor about 30 million years ago. Since then, the limestone has been uplifted, exposed, and eroded by the wind and the sea. Each of the limestone layers are separated by a thin sheet of mudstone in an arrangement known as st ...[Read More]

Natural hazards workshop videos are online!
Every year, the EGU host a two day workshop for primary and secondary school teachers during the General Assembly. Geosciences Information For Teachers (GIFT) workshops aim to shorten the time between discovery and textbook, while providing teachers with material that can be used in the classroom. This year, the workshop was on natural hazards, with scientists from the fields of seismology, volcan ...[Read More]
Imaggeo on Mondays: The perfect partnership
Pogonophores are deep sea worms that thrive in dark, deep sea conditions thanks to the presence of symbiotic bacteria. The bacteria are chemoautotrophic, that is, they fix carbon through oxidation processes, rather than using light to fix it, as is the case for photosynthesis. By utilising oxygen in the water, the bacteria can oxidise compounds such as hydrogen sulphide in order to fix carbon. The ...[Read More]
Vegetation research in Finnish Lapland: mountains, sunshine and reindeer
People started warning me about the mosquitoes back in April. It sounded grim. But when I arrived in Finnish Lapland in August, the mozzies had peaked earlier in the season when temperatures were unusually high, and were all dead. This was a fortunate escape: Miska Luoto of the University of Helsinki and his team of researchers, who I was following as part of an EGU Science Journalism Fellowship, ...[Read More]
Resource site for young scientists launched!
Early career researchers make up a large proportion of the EGU membership and students (both graduate and undergraduate) regularly make up about a third of General Assembly participants. With so many young scientists involved in the EGU, it’s time we had something that caters for them – the young scientists’ website! The new website is a hub of information on jobs, events and resources that ...[Read More]
Imaggeo on Mondays: Curl up under a peat blanket
Rannoch Moor is the largest area of unbroken (no houses, no roads) blanket bog in the United Kingdom. Blanket bogs – as their name suggests – blanket the ground in an extensive layer of peat. They form in regions where there is high rainfall and comparatively little evapotranspiration. These waterlogged conditions are found throughout much of the northern hemisphere, and allow blanket bogs to form ...[Read More]
