Imaggeo on Mondays: A Bubbling Cauldron

Imaggeo on Mondays: A Bubbling Cauldron

Despite being a natural hazard which requires careful management, there is no doubt that there is something awe inspiring about volcanic eruptions. To see an erupting volcano up close, even fly through the plume, is the thing of dreams. That’s exactly what Jamie  Farquharson, a researcher at Université de Strasbourg (France) managed to do during the eruption of the Icelandic volcano Bárðarbunga. R ...[Read More]

My film is ready, now what?

My film is ready, now what?

It’s no secret that at EGU we believe using film as a medium to communicate science and engage the public with research is a great tool! So much so that we organise an annual competition for early career scientists (ECS) to produce a three-minute video to share their research with the general public, as well as publishing film how-to-guides on our blog and organising film-making workshops at our G ...[Read More]

Image of the Week —  Looking for ice inside a volcano !

Who would think that one of the world’s most active volcano shelters the southernmost persistent ice mass in Europe!? Yes, you can find ice inside Mount Etna! Located at an altitude of about 2,040 m above sea level, the Ice Cave  (Grotta del Gelo) is well known among Mt Etna’s volcanic caves due to the presence of columns of ice on its walls and floor which occupy about the 30% of the ...[Read More]

New study of natural CO2 reservoirs: Carbon dioxide emissions can be safely buried underground for climate change mitigation

New study of natural CO2 reservoirs: Carbon dioxide emissions can be safely buried underground for climate change mitigation

New research shows that natural accumulations of carbon dioxide (CO2) that have been trapped underground for around 100,000 years have not significantly corroded the rocks above, suggesting that storing CO2 in reservoirs deep underground is much safer and more predictable over long periods of time than previously thought, explains Suzanne Hangx a postdoctoral researcher at the University of Utrech ...[Read More]

Fieldwork at 5,000 meters in altitude

Fieldwork at 5,000 meters in altitude

Imja Lake is one of the largest glacial lakes in the Nepal Himalaya and has received a great deal of attention in the last couple decades due to the potential for a glacial lake outburst flood. In response to these concerns, the UNDP has funded a project that is currently lowering the level of the lake by 3 m to reduce the flood hazard. The aim of our research efforts is to understand how quickly ...[Read More]

Revamping the EGU blog network: call for bloggers

Revamping the EGU blog network: call for bloggers

The EGU blog network is getting a make-over! Since 2013 the network blogs have enjoyed thought-provoking and engaging contributions by Simon Redfern, Dan Schillereff and Laura Roberts, Jon Tennant, as well as Will Morgan on a range of topics: from the workings of the inner Earth, through to geomorphology, palaeontology and air quality. However, the individual circumstances of the bloggers now mean ...[Read More]

Imaggeo on Mondays: Rock glaciers

Imaggeo on Mondays: Rock glaciers

Picture a glacier and you probably imagine a vast, dense mass of slow moving ice; the likes of which you’d expect to see atop the planet’s high peaks and at high latitudes. Now, what if not all glaciers look like that? Take some ice, mix in some rock, snow and maybe a little mud and the result is a rock glacier. Unlike ice glaciers (the ones we are most familiar with), rock glaciers have very litt ...[Read More]

Geosciences Column: The World’s soils are under threat

Geosciences Column: The World’s soils are under threat

An increasing global population means that we are more dependant than ever on soils. Soils are crucial to securing our future supplies of water, food, as well as aiding adaptation to climate change and sustaining the planet’s biosphere; yet with the decrease in human labour dedicated to working the land, never have we been more out of touch with the vital importance of this natural resource. Now, ...[Read More]

Image of the week – The winds of summer (and surface fluxes of winter)

Antarctica is separated from the deep Southern Ocean by a shallow continental shelf. Waters are exchanged between the deep ocean and the shallow shelf, forming the Antarctic cross-shelf circulation: Very dense waters leave the shelf as Antarctic Bottom Water (AABW) that will then flow at the bottom of all oceans. Meanwhile, relatively warm water from the Southern Ocean, Modified Circumpolar Deep W ...[Read More]
