Geosciences Column: Earthquakes and depleted gas reservoirs; what comes first?

An ever growing population means the requirement for resources to fuel our modern lifestyles grows too. Be it in mining, oil/gas extraction or the improvement of renewable technologies, the boundaries of where and how we access resources are constantly being pushed. Previously inaccessible resources become viable prospects as demand increases and our technological know-how advances. Hand in hand w ...[Read More]

Geoscience hot topics – Part I: The Earth’s past and its origin

What are the most interesting, cutting-edge and compelling research topics within the scientific areas represented in the EGU divisions? Ground-breaking and innovative research features yearly at our annual General Assembly, but what are the overarching ideas and big research questions that still remain unanswered? We spoke to some of our division presidents and canvased their thoughts on what the ...[Read More]

Volcanoes of the Ethiopian Rift Valley

November 17, 2015

The great Rift Valley of Ethiopia is not only the cradle of humankind, but also the place on Earth where humans have lived with volcanoes, and exploited their resources, for the longest period of time. Perhaps as long ago as 3 Million years, early hominids began to fashion tools from the volcanic rocks from which the Rift Valley was floored, including basalt and obsidian. The Ethiopian Rift Valley ...[Read More]

My DEFENCE! Follow live tweets with #129I @ 2:30pm ET

My PhD defence is this week (Wednesday) at 2:30pm ET. I am feeling pretty good about the whole thing but at the same time nervous. I just don’t know exactly what to expect. I have a sort of idea of what the questions might cover and where my assumptions or conclusions might be challenged. However, the uncertainty of all this is what is making me nervous. I have gotten lots of good advice fro ...[Read More]

Imaggeo on Mondays: Drilling a landslide

That landslides are hazardous goes without saying; the risk posed by them will largely depend on where they occur and their exact characteristics, which makes understanding the mechanisms which trigger them, as well as predicting when they might happen, extremely difficult. Today’s Imaggeo on Mondays image, brought to you by Ekrem Canli, a PhD student at the University of Vienna, is an example of ...[Read More]

Yet another way we are altering Earth’s natural functioning

So it has been a while since I last blogged, attributed to various excuses – fieldwork, moving job, moving house – but moving forwards I intend to spend more time discussing the myriad aspects of geoscience I find fascinating. One good example is a recent paper from Janice Brahney (University of British Columbia) and colleagues in Global Biogeochemical Cycles entitled ‘Is atmospheric p ...[Read More]

GeoPolicy: EGU sciences on debate at the European Parliament

The adoption of legislation within the European Union (EU) is a complex process involving many steps. In my first blog post in this GeoPolicy series I highlighted an example of this process. Several draft legislation pieces are currently being assessed within the European Parliament (EP) and Council of Ministers (Council) that have been influenced by EGU-related science. This blog post summarises ...[Read More]

Image of the Week — What’s up with the sea-ice leads?

This illustration shows two Synthetic Aperture Radar (SAR) images taken over sea ice in the Arctic Ocean. Both images are polarimetric and the different colours reflect the different polarimetric channels of the SAR (red = VV, green = HV and blue = HH). The two images are from the two satellites “ALOS-2” and “RADARSAT-2”. These are equipped with radars that operate at wavel ...[Read More]

Sunshine, ice cores, buckets and ALE: Antarctic Fieldwork

My Antarctic adventure started from Punta Arenas at the bottom of Chile, opposite Tierra del Fuego, on New Years Eve 2014 after a long journey from Heathrow via São Paulo and Santiago. Punta Arenas Punta Arenas is where Shackleton organised the rescue of his men from Elephant Island after his voyage to South Georgia in the James Caird. It is also where I met my PhD supervisors Chris Fogwill and Ch ...[Read More]
