The volcanic Lanzarote is the easternmost of the Canary Islands, located in the Atlantic Ocean approximately 125 km off the coast of Africa. One of its most famous attractions is the system of caves known as La Cueva de los Verdes (Greens’ Cave), created around 3,000-4,500 years ago by lava from the now extinct Monte …[Read More]

Imaggeo on Mondays: Sunset on the Black Sea coast
In the context of human history, few bodies of water are as storied as the Black Sea, located at the juncture of Europe, Asia, and the Middle East. Countless cargo ships and frigates have sailed its waters, over 1,100 km in length from east to west, daunting enough that the Ancient Greeks believed its eastern …[Read More]
Geosciences Column: Don’t blame bacteria – nitrous oxide production in the ocean
In this month’s Geosciences Column, Celso Gomes highlights a recent result published in EGU’s Biogeosciences on the role of a particular single-celled microorganism in the production of nitrous oxide in the ocean. About 30% of atmospheric nitrous oxide (N2O), a greenhouse gas, is a product of the ocean. Therefore, by studying the mechanisms behind the oceanic …[Read More]
Imaggeo on Mondays: The broken heart
We humans have a tendency to see familiar shapes in things such as animals in clouds, faces on Mars, and even food in rocks. The photographer, Natalia Rudaya saw a broken heart in a curious Taiwanese rock, the centrepiece of the beautiful photograph we are featuring this week. Aside from its interesting shape, the Broken …[Read More]
GeoTalk: Dr Guillermo Rein
This week, we are excited to introduce a new monthly blog column called GeoTalk, featuring short interviews with geoscientists about their research. To kick-start this regular Q&A series, we talked to Dr Guillermo Rein of Imperial College London about “the largest fires on Earth” and how they can contribute to greenhouse gas emissions. First, could …[Read More]
Imaggeo on Mondays: Jökulsárlón
This photo of an awe-inspiring icy landscape is without a doubt one of the best we have ever featured in our weekly Imaggeo on Mondays. The Icelandic glacial lagoon Jökulsárlón is gloomy and cold. Yet the brilliant blue of the ice and the turquoise of the water stand out beautifully in this image, giving it …[Read More]
Imaggeo on Mondays: Water or new iridescent fluid?
At ambient conditions, water is an odourless, tasteless, transparent liquid. It’s a vital fluid yet it has very simple properties. Unlike soap bubbles, for example, water is not iridescent – it does not appear to change colour when we view it from different angles. Unless, of course, there is something colourful in the background that …[Read More]
Imaggeo on Mondays: Cordillera del Paine
Images such as the one above inspire scientists and nature lovers alike. This photograph, showing a Chilean landscape with elements representative of various Earth-science disciplines, is simply stunning. In a beautiful mix of shapes and colours, a quiet lake with floating icebergs appears tucked in between a roughed mountain in the background and a colourful …[Read More]
Geosciences Column: For permafrost, (sediment) size does matter
In this month’s Geosciences Column, David Bressan – now a regular EGU contributor – highlights a recent result published in The Cryosphere with implications on the occurrence and preservation of alpine permafrost. The last 150 years saw an increase of 0.8°C in the Earth’s mean global temperature. In mountain ranges like the European Alps, however, this …[Read More]
Imaggeo on Mondays: Kerlingarfjöll
Iceland, with its stunning volcanic landscapes, is one of the world’s most geologically rich countries. Kerlingarfjöll, featured in this week’s image, is a prime example of that. This Icelandic mountain range, covering an area of 150 square kilometres, formed during a volcanic eruption in the Late Pleistocene – some 100 thousand years ago. “Kerlingarfjöll is …[Read More]
