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]

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]
Imaggeo on Mondays: A fly by some fantastic farming
This week’s Imaggeo on Mondays is brought to you by Kristof Van Oost, a scientist from the Georges Lemaître Centre for Earth and Climate Research (UCL) in Belgium. He tells us how local organic farms are being managed to ensure a lot of carbon stays in the soil… This is a picture of the organic farm Het Open Veld in Leuven, Belgium. The farm is built around an alternative agriculture model in whic ...[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: Long live the lichen!
Lichens are amazing organisms. They are a composite of algae and fungi, each of which supports the other through the exchange of nutrients (fungi to algae) and carbon (algae to fungi). They are also capable of making a home out of seemingly inhospitable rock surfaces – and what’s more – making the most of these surfaces to release the nutrients they need to grow. The quartzite above is home to the ...[Read More]
Put it in a nutshell – or in this case a 21 ft container
In his final post from the Floating University, Jens Weiser shares what it’s like to be part of an oceanographic research cruise and sums up some of the best experiences he’s had on board… I started this series asking whether anyone of you had ever thought about joining a research cruise. Now that this cruise is coming to an end, I can only strongly advise everyone who might have responded t ...[Read More]
A dangerous fish in the lab and a Vibrocorer on the move – who said research was monotonous?
Earlier this month Jens Weiser set off aboard a research vessel fondly known as the Floating University to find out more about the oceans off southern Africa. After several weeks at sea, Weiser has some exciting findings to report back from FS Meteor as he and 14 other young scientists explore the region’s biology and geology… A certain routine has developed over the last week here on board. The t ...[Read More]
Seawater, fish larvae and sediments – a snapshot of an ecosystem off South Africa
Earlier this month Jens Weiser set out from southern Africa to find out more about the region’s biology and geology. Back aboard FS Meteor, he’s searching for layers of lagoonal muds to see what the climate was like here in the late Quaternary… After quite a lot of transit, we arrived at our first big station off Durban on Wednesday afternoon. On our way here we used the time to introduce ourselve ...[Read More]
Geoscience under the tree
In a festive-themed post, EGU Media and Communications Manager Bárbara Ferreira selects a plethora of geoscience-inspired Christmas presents, which you could give to your favourite researcher. Please note that, with the exception of the last one, the items listed below are not necessarily recommended or endorsed by the EGU. For me Christmas is more about eating large amounts of food and celebratin ...[Read More]
…Ever thought about joining a research cruise?
Over the next month Jens Weiser, a masters student at the University of Bremen, will be reporting from a research cruise off southern Africa. This week he’s setting the scene and setting seaward with 14 other young scientists in a bid to understand more about the region’s biology and geology… When I started my Masters programme, Marine Geosciences, at the University of Bremen one and a half years ...[Read More]
