Imaggeo on Mondays: Friends in the field

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]

Imaggeo on Mondays: Pitter-patter of little paws in Patomsky crater

This week’s Imaggeo on Mondays is brought to you by Dmitry Demezhko, who describes how Patomsky crater may have formed and why it keeps scientists puzzling… Patomsky crater, also known as Patomskiy crater or the Patom cone, sits in the Irkutsk Region of Eastern Siberia. The site is a curious cone with a crater at the top and a small mound in the center. The cone totals some 39 metres in height and ...[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: White mist on White Island

White Island, also known as Whakaari, is an active stratovolcano off the coast of New Zeland’s North Island, nested in the northern end of the Taupo Volcanic Zone. Much of its activity is made up of bubbling mud pools and steamy, sulphurous clouds from fumaroles like the one below – sights that attracts many a tourist to the marine volcano. Over the last 200 or so years, a large part of White Isla ...[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]

Imaggeo on Mondays: Moulding Malaspina’s moraines

There are many different types of glaciers, each defined by where they’re located and how they terminate. Piedmont glaciers are those that flow out from a confining valley and spill out into the open, forming wide lobes. This one is Malaspina Glacier, which spreads out over the Seward Ice Field. Stretching 45 kilometres over the lowlands towards the sea, and spanning some 65 kilometres across, Mal ...[Read More]
