Imaggeo on Mondays: In the belly of the beast

Imaggeo on Mondays: In the belly of the beast

Conducting research inside a volcanic crater is a pretty amazing scientific opportunity, but calling that crater home for a week might just be a volcanologist’s dream come true, as Alexandra postdoctoral researcher at the Institut de Physique du Globe de Strasbourg, describes in this week’s Imaggeo on Mondays. This picture was taken from inside the crater of Mount St Helens, a stratovolcano ...[Read More]

Image of the Week – A high-resolution picture of Greenland’s surface mass balance

Image of the Week – A high-resolution picture of Greenland’s surface mass balance

The Greenland ice sheet – the world’s second largest ice mass – stores about one tenth of the Earth’s freshwater. If totally melted, this would rise global sea level by 7.4 m, affecting low-lying regions worldwide. Since the 1990s, the warmer atmosphere and ocean have increased the melt at the surface of the Greenland ice sheet, accelerating the ice loss through increased runoff of meltwater and i ...[Read More]

Union-wide events at EGU 2017

Union-wide events at EGU 2017

Wondering what to expect at the General Assembly this year? Here are some of the highlights: Union Symposia (US) For events which will have general appeal, regardless of your field of research, look no further than the Union Symposia.  In particular, if you want to stand up for science at a time when (some) politics seems at odds with science, come along to Union Symposia 3, Make Facts Great Again ...[Read More]

Marching for Science in Vienna

Marching for Science in Vienna

On 22 April, Earth Day and the day before the start of the EGU General Assembly, scientists and science enthusiasts across the globe will be marching to celebrate science and to call for the safeguarding of its future. While the main march is taking place in Washington D.C. in the US, there are hundreds of satellite marches happening around the world, including in Vienna. Representatives of both t ...[Read More]

Knowing the ocean’s twists and turns

Knowing the ocean’s twists and turns

Navigating the ocean demands a knowledge of its movements. In the past, sailors have used this knowledge to their advantage, following the winds and the ocean currents to bring them on their way. Prior to mutiny in 1789, Captain Bligh – on the HMS Bounty – famously spent a month attempting to pass westward through the Drake Passage, around Patagonia’s Cape Horn. Here the westerly ...[Read More]

Minds over Methods: Reconstruction of salt tectonic features

Minds over Methods: Reconstruction of salt tectonic features

What is the influence of salt tectonics on the evolution of sedimentary basins and how can we reconstruct such salt features? Michael Warsitzka, PhD student at the Friedrich Schiller University of Jena, explains which complementary methods he uses to better understand salt structures and their relation to sedimentary basins. Enjoy!   Reconstruction of salt tectonic features from analogue mode ...[Read More]

Musical groundwater?

Musical groundwater?

Post by Kevin Befus, University of Wyoming I don’t mean to get your hopes up, but keep them up there. I’m not talking about recording the sonorific excitement that is groundwater flow. And, I’m not talking about the squeak of a pump handle, the gurgling of a spring, the grumble of a generator, or the roar of a drill rig. Rather, I want to share with you some songs that reference groundwater in one ...[Read More]

Imaggeo on Mondays: Atmospheric gravity waves

Imaggeo on Mondays: Atmospheric gravity waves

From the tiny vibrations which travel through air, allowing us to hear music, to the mighty waves which traverse oceans and the powerful oscillations which shake the ground back and forth during an earthquake, waves are an intrinsic part of the world around us. As particles vibrate repeatedly, they create an oscillation, which when accompanied by the transfer of energy, creates a wave.  The way in ...[Read More]
