PICO in the picture

Like everyone else, in the beginning I was skeptical of the newly introduced presentation format at the EGU – the PICO sessions. PICO stands for Presenting Interactive Content. Half talk, half poster – this is a new design that demands a completely new and unfamiliar preparation of the presenter, and yes admittedly at first this meant additional work. However, already during the creation of my fir ...[Read More]

Karaoke, geodynamics, and a bit of history

Let me just talk to you about what I have been doing with my free time recently: I discovered a feature from Google Books named Ngram viewer which allows you to make graphs that show how words or phrases have occurred in a selection of books (e.g., English) over the selected years. I have of course been playing with this thing! You can imagine how exciting my weekends are. In all seriousness, thou ...[Read More]

Capturing a Whole Total Eclipse of the Sun: Megamovie

Capturing a Whole Total Eclipse of the Sun: Megamovie

by Hugh S Hudson (U. of Glasgow and UC Berkeley) Normally solar eclipses give an observer only a fleeting moment (minutes at most) to enjoy the solar corona. We aim to amplify that considerably in the August 21 eclipse across North America. The plan is simple: Megamovie will capture everybody’s images, especially those from a group of 1,000 photographc volunteers, and compile them into an op ...[Read More]

Image of the Week – Fifty shades of snow

Image of the Week – Fifty shades of snow

When I think of snow, I tend to either think about the bright white ski slopes in the mountains or the large white areas in the Arctic. However, natural phenomena can lead to colorful snow. Our Image of the Week shows snow can be green! Snow can also turn orange, pinkish, grey and even yellow… But where do these different shades of snow come from? White The most common color of snow is white (see ...[Read More]

Don’t be a hero – unless you have to

Don’t be a hero – unless you have to

The Geodynamics 101 series serves to show the diversity of topics and methods in the geodynamics community in an understandable manner for every geodynamicist. PhD’s, postdocs, full professors, and everyone in between can introduce their field of expertise in a lighthearted, entertaining manner and touch on some of the outstanding questions and problems related to their method of choice. Thi ...[Read More]

Image of the Week – Summer is fieldwork season at EastGRIP!

As the days get very long, summer is a popular season for conducting fieldwork at high latitudes. At the North East Greenland Ice Stream (NEGIS), the East Greenland Ice-core Project (EastGRIP) is ongoing. Several scientists are busy drilling an ice core through the ice sheet to the very bottom, in continuation to previous years (see here and here). This year, amongst others, several members from t ...[Read More]

Too early seen unknown, and known too late!

Romeo and Juliet famously had some identification problems: they met, fell in love, and only afterwards realised that they were arch enemies, which *spoiler* resulted in their disastrous fate. Oops. Of course, this could happen to anybody. However, we do not want this to happen to you! We want you to know who we, the EGU Geodynamics Blog Team, are! So, in order to prevent any mishaps during future ...[Read More]

Minds over Methods: Block modeling of Anatolia

 

How can we use GPS velocities to learn more about present-day plate motions and regional deformation? In this edition of Minds over Methods, one of our own blogmasters Mehmet Köküm shares his former work with you! For his master thesis at Indiana University, he used block modeling to better understand the plate motion and slip rates of Anatolia and surrounding plates.   Using block modeling t ...[Read More]

Image of the Week — High altitudes slow down Antarctica’s warming

When it comes to climate change, the Arctic and the Antarctic are poles apart. At the north of the planet, temperatures are increasing twice as fast as in the rest of the globe, while warming in Antarctica has been milder. A recent study published in Earth System Dynamics shows that the high elevation of Antarctica might help explain why the two poles are warming at different speeds. The Arctic vs ...[Read More]

Pre-plate-tectonics on early Earth: How to make primordial continental crust

Pre-plate-tectonics on early Earth: How to make primordial continental crust

The sequence of events before continental crust formation has long been contested. Numerical simulations performed by Rozel and colleagues imply that the key to the puzzle could lie in the intrusive magmatism. Despite several decades of research on the topic, the trigger of proto-continental crust formation on early Earth remains an enigma. However, magmatic processes may hold the key to unravelli ...[Read More]
