Convection in eggs

Convection in eggs

Happy Easter everybody! It is that time of year again when you wake up excitedly on Easter Sunday and run into the garden to find the chocolate eggs the Easter Bunny hid for you! What? That’s just me? Hm. Well, in any case, you will probably have a couple of extra days off from work and this should be celebrated with a themed blog post! As you know, geodynamics is about the large scale dynam ...[Read More]

Minds over Methods: Experimental seismotectonics

For our next Minds over Methods, we go back into the laboratory, this time for modelling seismotectonics! Michael Rudolf, PhD student at GFZ in Potsdam (Germany), tells us about the different types of analogue models they perform, and how these models contribute to a better understanding of earthquakes along plate boundaries.   Experimental seismotectonics – Seismic cycles and tectonic ...[Read More]

Image of the Week – Geothermal heat flux in Antarctica: do we really know anything?

Geothermal heat flux is the major unknown when we evaluate the temperature and the presence/absence of water at the bed of the Antarctic Ice Sheet. This information is crucial for the Beyond Epica Oldest Ice project, which aims to find a continuous ice core spanning 1.5 million years (see this previous post). A lot of work has been done* to determine geothermal heat flux under the entire Antarctic ...[Read More]

A geomorphologist’s winter refuge

– written by Michael Dietze, GFZ Potsdam – Why Swedish, Finnish and German geomorphologists meet in the boreal zone to drill holes into icy rivers and frozen ground. There are many ways to counter the lazy days between Christmas and the EGU meeting. One of the more promising ones is this: think of doing collaborative field work in February, in northern Sweden, on and around a frozen ri ...[Read More]

Help us fight patriarchy, one comic strip at a time!

Women in science/geodynamics: a topic we have discussed before and should continue to discuss, because we’re not there yet. In this new Wit & Wisdom post, Marie Bocher, postdoc at the Seismology and Wave Physics group of ETH Zürich, discusses a range of all-too-common encounters women face and a possible solution to awareness: comics (drawn by Alice Adenis, PhD student at ENS Lyon). You ...[Read More]

Cosmic rays – messengers from space

Cosmic rays – messengers from space

Cosmic rays (CRs), are not actually rays, but highly energetic charged particles of extraterrestrial origin. The life cycle of a cosmic ray particle starts with its birth at some point in the Universe, its travel at nearly the speed of light and finally with its death ( e.g. at a detector). These highly energetic particles strike our planet from all directions and thus provide a constant backgroun ...[Read More]

What is coming at the next EGU’s General Assembly?

The next EGU’s General Assembly is taking place in three weeks! We bet you already started planning your program for the week, and that Natural Hazard (NH) sessions are included, and, especially if you are an Early Career Scientist, you have found many sessions and courses targeting your specific needs and interests. What fits more to your interests: Attend talks and posters, learn and improve ski ...[Read More]

Image of the Week – Broccoli on Kilimanjaro!

On the plateau of Kilimanjaro, Tanzania, the remnants of a glacier can be found and the ice from that glacier contains a rather interesting feature – Broccoli! Not the vegetable, but bubbles that look a lot like it. Our Image of the Week shows some of these strange “Broccoli Bubbles”. Read on to find out more about where these were found and how we can see them. There is not much ice left on the m ...[Read More]

Climate: Past, Present & Future

How to reconstruct past climates from water stable isotopes in Polar ice cores ?

How to reconstruct past climates from water stable isotopes in Polar ice cores ?

Ice cores are a favored archive to study past climates, because they provide a number of indications on the history of the climate and of the atmospheric composition. Among these, water stable isotopes are considered as a very reliable temperature proxy. Yet, their interpretation is sometimes more complicated than a simple one-to-one correspondence with local temperature and requires intercomparis ...[Read More]
