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]

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]

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: 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]

GeoTalk: Matt Herod on awesome outreach and education

Matt Herod has long been part of the EGU Blog Network, where he writes about all things geochemistry from his base in the University of Ottawa. In this week’s GeoTalk, we had the chance to talk to Matt about all the other science communication activities he’s been up to – from mentoring kids in Canada to speaking science in schools… This year GeoSphere had its first birthday as part of the EGU Blo ...[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]

Imaggeo on Mondays: Hot and cold – how ash influences glacial landscapes

This week’s Imaggeo on Mondays is brought to you by Joanna Nield, a lecturer in physical geography at the University of Southampton. Nield explains how volcanic eruptions can impact glaciers and how ash fall can both accelerate and slow down glacial melt… This photo was taken at Fjallsjökull, Iceland in July 2011, shortly after the eruption of Grímsvötn volcano (21 – 30 May 2011).  The Gríms ...[Read More]

The Geology of Skyrim: An unexpected journey

Back in January I did a talk at an event called Science Showoff, a comedy night based in London where scientists stand up in front of an audience in a pub and talk about funny stuff to do with their work. I talked about video games. Not any video game however, I talked about The Elder Scrolls V: Skyrim. For those of you who don’t know what this is, it’s a fantasy role playing video game. It is a g ...[Read More]

Imaggeo on Mondays: Hekla’s history

Iceland is well known for its extensive volcanism. Situated amid the northernmost part of the Mid-Atlantic Ridge, the spreading centre is a hub of volcanic activity, from Krafla in the north to the young volcanic island of Surtsey in the south. Hekla is one of the country’s most active volcanoes – both in terms of erupted material and eruption frequency, and lies at the heart of a 40 kilomet ...[Read More]
