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

Suzanne Hangx July 28, 2016

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]

Revamping the EGU blog network: call for bloggers

Bárbara Ferreira July 26, 2016

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

Laura Roberts-Artal July 25, 2016

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

Laura Roberts-Artal July 22, 2016

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]

Imaggeo on Mondays: an impressive testimony to the collision between Africa and Europe

Angelika Jung-Hüttl July 18, 2016

The huge fold in the flank of the 2969 m high Dent de Morcles (in Waadtland Alps, Switzerland) is an impressive testimony to the collision between Africa and Europe (which began some 65 million years ago). The layers, originally deposited on the sea floor in a horizontal position, were compressed and shifted. The darker parts developed during the Tertiary period (66 million years ago). They are yo ...[Read More]

GeoTalk: Matt Taylor of ESA’s Rosetta mission

Laura Roberts-Artal July 15, 2016

In November 2014, space exploration history was made. Millions of kilometres away, orbiting a piece of ice and rock, the European Space Agency’s (ESA) Rosetta mission sent its probe Philae to become the first spacecraft to soft-land on a comet. After the tense 7-hour wait that followed the separation from the main orbiter, a tweet confirmed that the little lander had successfully completed the fir ...[Read More]

GeoPolicy: 8 ways to engage with policy makers

Sarah Connors July 13, 2016

Scientific research is usually verbally communicated to policy officials or through purposefully written documents. This occurs at all levels of governance (local, national, and international). This month’s GeoPolicy post takes a look at the main methods in which scientists can assist in the policy process and describes a new method adopted by the European Commission (EC) that aims to enhance scie ...[Read More]

Imaggeo on Mondays: The glacial landscape of Yosemite

Laura Roberts-Artal July 11, 2016

Yosemite National Park, in California, is renowned for its beautiful and striking landscapes. So much so, this is the second time it has feature on the blog this summer. While our last post on the park focused on the ancient volcanic history of its landscape, in this post we fast forward to the Plesitocene (some 110,000 to 12,000 years ago) to discover more about how glaciers shaped Yosemite’s lan ...[Read More]

Imaggeo on Mondays: Why is groundwater so important?

Laura Roberts-Artal July 4, 2016

Groundwater is an often underestimated natural resource, but it is vital to the functioning of both natural and urban environments. Indeed, it is a large source of drinking water for communities world-wide, as well as being heavily used for irrigation of crops and crucial for many industrial processes. The water locked in the pores and cracks within the Earth’s soils and rocks, also plays an impor ...[Read More]
