Unseen but not unfelt: resilience to persistent volcanic emissions

The last decade has been inundated with reports of environmental disasters impacting the lives of billions of people around the world.  While news coverage of floods, hurricanes, earthquakes or wild fires are always accompanied with spectacular images of destruction that emphasise the speed at which they strike, a myriad of slow and latent hazards have been left in the shadow of the public attenti ...[Read More]

The EUGEN e.V. meeting – a unique (geological) experience

Extracurricular activities for current and former geosciences students provide great value to early career scientists in terms of networking and broadening their scientific horizon. PhD student Maximilian Döhmann, who studies rock deformation with numerical models based on high temperature and pressure torsion experiments in the Geodynamic Modelling group of GFZ Potsdam, shares his experiences wit ...[Read More]

Volcanic Ash Particles Hold Clues to Their History and Effects

Volcanic Ash as an Active Agent in the Earth System (VA3): Combining Models and Experiments; Hamburg, Germany, 12–13 September 2016 Volcanic ash is a spectacular companion of volcanic activity that carries valuable information about the subsurface processes. It also poses a range of severe hazards to public health, infrastructure, aviation, and agriculture, and it plays a significant role in bioge ...[Read More]

Image of the Week – Powering up the ground in the search for ice

  In an earlier post, we talked briefly about below-ground ice and the consequences of its disappearing. However, to estimate the consequences of disappearing ground ice, one has to know that there actually is ice in the area of study. How much ice is there – and where is it? As the name suggests, below-ground ice is not so easy to spot with the naked eye. Using geophysical methods, however, ...[Read More]

Why there should (not) be more women in geodynamics

Why there should (not) be more women in geodynamics

Nowadays, equality is cool. Everyone is always going on about how women and men should get the same opportunities. In science, and hence, geodynamics, women are still a bit behind men for both historical (women only recently started graduating more in exact sciences) and unconscious-bias reasons. Therefore, there are lots of programs in order to stimulate women to go into science and, more importa ...[Read More]

Investigation of methane emissions in marine systems

Ever wondered how we can measure methane emssions from the seafloor ? And ever wanted to steer a mini submarine remotely operating vehicle (ROV)? Well here´s your chance! Have look at this blog post on analyzing methane emissions using ROVs and you´re ready to embark!    The goal is to determine when the gas leak started and how the fluid flow systems work. With our research, we can contribut ...[Read More]

Miho Janvier – The Quest for Solar Storms

In this month’s (first ever for our blog) Life of a Scientist interview, we are very happy to talk to Dr Miho Janvier, a Researcher at the Institut d’Astrophysique Spatiale in Orsay (France), whose work has shed some light on the understanding of solar eruptions and coronal mass ejections  (or solar storms) from their birth in the Sun’s corona to their evolution in interplanetary space ...[Read More]

Image of the Week – ROVing in the deep…

Robotics has revolutionised ocean observation, allowing for regular high resolution measurements even in remote locations or harsh conditions. But the ice-covered regions remain undersampled, especially the ice-ocean interface, as it is still too risky and complex to pilot instruments in this area. This is why it is exactly the area of interest of the paper from which our Image of the week is take ...[Read More]

Minds over Methods: Making ultramylonites

“Summer break is over, which means we will continue with our Minds over Methods blogs! For this edition we invited Andrew Cross to write about his experiments with a new rock deformation device – the Large Volume Torsion (LVT) apparatus. Andrew is currently working as a Postdoctoral Research Associate in the Department of Earth and Planetary Sciences, Washington University in St. Louis, USA. ...[Read More]
