Back in August, I attended Oceanhackweek 2020. As an oceanographer by trade and free software nerd by heart, I loved the idea of an event that combined the two. I looked forward to learning from other oceanographers and coders, and perhaps giving something back to the free software community. What is a hackweek/hackathon? If you have yet to dip your toes in the wonderful world of free software, th ...[Read More]
As Antarctica’s mass loss increases, the threat of crossing tipping points both in the ice sheet and the surrounding Southern Ocean is increasing. But what actually is a tipping point? Have tipping points already been crossed in the past? And what might the future hold? What do we mean by a “tipping point”? Scientifically speaking, a tipping point is generally understood to be a threshold that, on ...[Read More]
Dr. Laura Gulia is a senior post-doc at the University of Bologna, Department of Physics and Astronomy. She has a strong experience in statistical seismology, seismicity analysis as well as seismic hazard and risk assessment. Recently, she investigated the spatio-temporal evolution of the earthquake size distribution throughout a seismic sequence focusing on the b-value, a parameter characterizing ...[Read More]
Each month we feature specific Divisions of EGU and during the monthly GeoRoundup we will be putting the journals that publish science from those Divisions at the top of the Highlights roundup. For October, the Divisions we are featuring are: Natural Hazards (NH), Hydrological Sciences (HS) and Seismology (SM). They are served by the journals: Geoscientific Model Development (GMD), Hydrology and E ...[Read More]
Women make up 50.8% of the worlds population, yet fewer than 30% of the world’s researchers are women. Of this percentage, BAME (Black Asia and Minority Ethnic) comprise around 5%, with less than 1% represented in geoscience faculty positions. The divide between women in the population and women in STEM needs to be addressed. Through a series of blog posts we hope to raise the voice of women in th ...[Read More]
With time to spare during self-isolation and local lockdown, Mark wonders: What programming language should I learn for my geoscience career? Dear Mark, The pandemic has made us look long and hard at our career choices. Were you inspired as a student by a cool field geologist in a documentary? Were you profoundly marked by that school trip at an active volcano? Did you fell in love with coral reef ...[Read More]
Geodynamics does not stop at the core-mantle boundary – the Earth’s outer core is a truly dynamic geosystem. This week Stefano Maffei (Research fellow) and Chris Davies (Associate Professor) from the School of Earth and Environment at the University of Leeds tell us more about the possible interplay between mantle and core and some of the remaining mysteries of the Earth’s magnetic field generatio ...[Read More]
In this photo taken on the Isle of Elba in Italy you can see several radiating crystals of greenish Hedenbergite, inter-grown with blackish coloured Ilvaite in skarn bodies. Skarn is an unique formation that formed as a result of the interaction between geothermal fluids and the host rock. In this case the geothermal fluids come from the Late Miocene Porto Azzurro monzogranite, and Mesozoic marble ...[Read More]
“Be thou as chaste as ice, as pure as snow”. Hamlet, Act 3 Scene 1 (W. Shakespeare) Snow and ice are not always as pristine as one may think. If you have ever walked on a glacier or on a snowfield during summer, you might have already noticed that. In fact, both snow and ice are often darkened by impurities. In this blog post, you will learn about the main processes leading to ice and snow darkeni ...[Read More]
Though giant earthquakes are disastrous, they provide essential information to investigate earthquake physics. In this week’s news and views, Thyagarajulu Gollapalli, a PhD student jointly from the Monash University and the Indian Institute of Technology, Bombay, discusses our present understanding of such big earthquakes and how advanced numerical models will help to get a more precise picture of ...[Read More]
