Dmitry Vlasov, a PhD Student and junior scientist from Lomonosov Moscow State University, brings us this week’s Imaggeo on Mondays. He shares his experience of taking part in a student scientific society expedition to Lake Baikal. This picture shows icy shores of Lake Baikal – a UNESCO World Heritage Site and the world’s largest natural freshwater reservoir (containing about one fifth of Ear ...[Read More]

Imaggeo on Mondays: The most powerful waterfall in Europe
On the menu this Monday is the opportunity to indulge in some incredible Icelandic geology. Take a look at a tremendous waterfall and the beautiful basalt it cuts through… Iceland is famous for its striking landscapes, from fiery volcanoes and fields of basalt to violent geysers and pools of the most fantastic blue. One of the country’s many geological gems is Dettifoss waterfall – a 100-met ...[Read More]
Imaggeo on Mondays: Turkey’s cotton castle
This week, Imaggeo on Mondays is brought to you by Josep Ubalde, who transports us to a wonderful site in western Turkey: a city of hot springs and ancient ruins dubbed cotton castle, after the voluminous white rocks that spread from the spring’s centre… Pamukkale is lies in Turkey’s inner Aegean region, within an active fault that favours the formation of hot springs. The spring’s hot water ...[Read More]
Imaggeo on Mondays: Fuelling the clouds with fire
Wildfires frequently break out in the Californian summer. The grass is dry, the ground parched and a small spark can start a raging fire, but burning can begin even when water is about. Gabriele Stiller sets the scene for a blaze beside Mono Lake, exploring the events that got it going and what it may have started in the sky… While on shores of Mono Lake in the summer of 2012, I spotted something ...[Read More]
GeoTalk: Want a record of historical floods? Ask the taxman
Extreme weather events, like catastrophic floods, are the malicious exclamation points of Earth’s chaotic and variable climate system; they arrive without warning and extract huge costs, both economic and humanitarian, from the communities they strike. Evidence suggests the frequency and severity of these events may be on the rise in a changing climate, but scientists struggle to place modern even ...[Read More]
GeoTalk: Claudia Cherubini and the art of characterising aquifers
This week in GeoTalk, we’re talking to Claudia Cherubini, a research professor from La Salle Beauvais Polytechnic Institute. Claudia shares her work in hydrogeological modelling and delves into how such models can be used in water management… Could you introduce yourself and tell us a little about what you’re currently working on? I am an environmental engineer with a PhD in hydrogeolo ...[Read More]
Imaggeo on Mondays: Winter waterfalls reveal their secrets
Cyril Mayaud is kicking of this week’s Imaggeo on Mondays with an insight into what waterfalls in winter can tell us about their local hydrology… The picture below shows the lower Peričnik waterfall during winter season. This cascade system is composed of two successive waterfalls that stretch some 16 metres (upper fall) and 52 metres (lower fall) high and is one of the most beautiful natur ...[Read More]
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: 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]
Imaggeo on Mondays: Carving polar canyons
This week Ian Joughin, a research scientist from the Polar Science Center at the University of Washington, takes us on the polar express to put glacial processes into perspective and find out what makes a moulin… This canyon formed when a melt lake on the surface of the Greenland Ice Sheet overflowed and created a stream that extended out toward a crevasse field. This outflow stream filled a creva ...[Read More]
