Numerically simulating production in geothermal reservoirs: application to the Groß Schönebeck deep geothermal facility.

Numerically simulating production in geothermal reservoirs: application to the Groß Schönebeck deep geothermal facility.

Producing deep geothermal energy involves using a well, which can be several kilometres deep, to extract hot water in the aim of using its heat to generate electricity or for industrial applications. The well is drilled into what’s called a geothermal reservoir; rock containing empty space, or porosity, which allows the passage or storage of fluids. Sometimes hot water is already sufficiently pres ...[Read More]

Minds over Methods: Experimental earthquakes

After our first edition of Minds over Methods, which was about Numerical Modelling, we now move to Rock Experiments! How can rock experiments be used to study processes within the Earth? We invited Giacomo Pozzi, PhD student at Durham University, to explain us how he uses rock experiments to study fault behaviour during earthquakes.   Experimental earthquakes to understand the weak behaviour ...[Read More]

Black Carbon: the dark side of warming in the Arctic

Black Carbon: the dark side of warming in the Arctic

When it comes to global warming, greenhouse gases – and more specifically CO2 – are the most often pointed out. Fewer people know however that tiny atmospheric particles called ‘black carbon’ also contribute to the current warming. This post presents a paper my colleague and I recently published in Nature Communications . Our study sheds more light into the chemical make-up of black ca ...[Read More]

[ECS Interview] On the surface of Churyumov-Gerasimenko with Philae and Anthony

Rosetta recently made a breathtaking dive towards the surface, bringing a wealth of science close from the surface, but also bringing the mission to its end. The operations might be over, but the science is not as there is still a lot of data to analyse, especially for the next generation of cometary scientists. To illustrate this new generation, we asked a few questions to an early career scienti ...[Read More]

EGU Abstract Submission Season

A new season just started – EGU 2017 abstract submission season! (http://meetingorganizer.copernicus.org/EGU2017/sessionprogramme). Since the 20th of October you can submit your abstracts to one or more of the many seismology sessions. Believe it or not but we counted 75 sessions that are related to seismology. Wow! We are all very excited to scroll through the programme and daydream about t ...[Read More]

Image of The Week – Plumes of water melting Greenland’s tidewater glaciers

October 28, 2016

Loss of ice from The Greenland Ice Sheet currently contributes approximately 1 mm/year to global sea level (Enderlin et al., 2014). The most rapidly changing and fastest flowing parts of the ice sheet are tidewater glaciers, which transport ice from the interior of the ice sheet directly into the ocean. In order to better predict how Greenland will contribute to future sea level we need to know mo ...[Read More]

When cooling causes heating

When cooling causes heating

                          Following the Montreal Protocol in the late 1980s, CFC (chlorofluorocarbon) were replaced by hydrofluorocarbons (HFC) as a refrigerant. Unfortunately, the HFC’s have a global warming potential (GWP) far greater than the well-known greenhouse gas (GHG), carbon dioxide. Apart from the fact that this was not kn ...[Read More]

Image of the Week — Listening to the Snow

When working in the middle of an ice sheet, you rarely get to experience the amazing wildlife of the polar regions. So what are we doing hundreds of kilometres from the coast with an animal tracker device? We are listening to the snow of course! It is not crazy; It is what Image of the Week today is all about! Going Wireless In June 2016, Liz Bagshaw and I travelled to the EGRIP (East Greenland Ic ...[Read More]
