Out in the field you encounter all sorts of wildlife and while mosquitos are the most frequent (and most unwelcome), they generally don’t interfere with your equipment or your data. The same can’t be said for all animals though, and many scientists have to strap their equipment out of reach, barricade it with barbed fences or place it in a relatively indestructible black box. It’s a particular pro ...[Read More]

Imaggeo on Mondays: Scope for science and art
Great geoscience photographs aren’t always shots of beautiful landscapes. Sometimes there are stunning things to see at a much smaller scale. This week’s Imaggeo on Mondays showcases one such curiosity and highlights how research images can reveal a lot about the natural world when exhibited as a form of art. Thin sections are a fantastic way of finding out more about rocks, soils and tissue struc ...[Read More]

For the love of rocks
We often have a way of seeing patterns in otherwise random features, and rock outcrops are no exception. Do you see the heart on its side? To the untrained eye an outcrop like this is simply a heart-shaped feature in an otherwise grey rock. But to the geologist, the layers, swirls, shapes and colours tell a story. The ribbons in the granite show that the rock has been subjected to sheer forces and ...[Read More]

Geosciences Column: Using tall trees to tot up tropical carbon
Forests in the tropics account for about half the above-ground carbon on Earth and as the trees grow older they are capable of storing more and more. In fact, their carbon-storing potential is so large that they are increasingly being viewed as a means of mitigating climate change. Take, for example, the United Nations effort to reduce degradation and deforestation by assigning value to forest car ...[Read More]

GeoTalk: Connecting geoscience and archaeology with Sophie Gangl
This week in GeoTalk, we’re talking to Sophie Gangl, a masters student from the University of Natural Resources and Life Sciences (BOKU), Vienna. Sophie tells us about the intersecting fields of geoscience and archaeology, and shares the benefits of presenting postgraduate projects at an international conference. Hi Sophie, can you tell us a little about yourself and what you’ve been investigating ...[Read More]

Imaggeo on Mondays: How sea urchins can help mitigate climate change
This week’s Imaggeo on Mondays stars the humble sea urchin – a creature suffering from the effects of climate change, but one that could also provide a way to sequester some of the CO2 responsible… Carbon dioxide and water react to form carbonic acid – a mixture of bicarbonate and hydrogen ions. Sea urchins bag the bicarbonate to grow bigger, stronger shells, or ‘tests’, but without a catalyst, th ...[Read More]

Imaggeo on Mondays: A feast of pancakes
The thought of pancake ice always makes me a little hungry – I just can’t help thinking about stacks of syrup-drowned pancakes, or crepes covered wish sugar and doused with lemon juice – but the science of pancake ice is quite a tempting topic too! Pancake ice occurs in areas where ice formation is repeatedly disturbed by water movement. In the Southern Ocean, the water extremely open and the swel ...[Read More]

Seeking young scientists! A great opportunity to get involved in the EGU
Young scientists make up a significant proportion of the EGU membership and it’s important to us that your voices get heard. One way to do this is by getting in touch with your division’s young scientist representative, or better yet, putting yourself forward as a young scientist representative for your division. Young scientist representatives are a vital link between the EGU and the young scient ...[Read More]

Geosciences Column: Getting a handle on glacial lakes
Glacial lake outburst floods (GLOFs) are caused when masses of meltwater are released from behind a glacier moraine. Moraines are piles of unconsolidated debris that have either eroded from the glacier valley or have been deposited by melting glaciers. When they fail, a huge volume of water can be released, threatening populations further down the valley. Moraine failure can be caused by avalanche ...[Read More]
