The Geodynamics 101 series serves to showcase the diversity of research topics and methods in the geodynamics community in an understandable manner. We welcome all researchers – PhD students to professors – to introduce their area of expertise in a lighthearted, entertaining manner and touch upon some of the outstanding questions and problems related to their fields. For our latest ‘Geodynamics 10 ...[Read More]

Famous geological sites: Delicate Arch, Utah
Delicate Arch is probably the most spectacular natural arch in Arches National Park, Utah. Delicate Arch is made of the Middle Jurassic Entrada Sandstone, which was deposited in various environmental settings, particularly beaches, tidal mudflats and deserts. Arches National Park attracts more than 1.5 million visitors per year.

Image of the Week – Why is ice colourful?
When you think of glacier ice, what colour first springs to mind? Maybe white, blue or transparent? Well, glacier ice can, in fact, be mesmerising and multi-coloured! Our image of the week shows thin sections of glacier ice under polarised light. These sections were cut from block samples of two Alpine glaciers in Switzerland (Chli Titlis and Grenzgletscher). In these images the individual ice c ...[Read More]

EGU 2018: convening a session
The European Geosciences Union (EGU) General Assembly 2018 took place in Vienna, Austria, from 8–13 April 2018 and brought together geoscientists from all over the world to one meeting covering all disciplines of the Earth, planetary and space sciences. If you are an early career research, convening a session at the EGU General Assembly can seem intimidating, especially if you are a first-time con ...[Read More]

Permafrost fever, do we need a doctor?
Today we will shed some light on permafrost thanks to Dr. Dmitry (Dima) Streletskiy. Dima is an Assistant Professor of Geography and International Affairs at the George Washington University. He leads several research grants focusing on various aspects of climate change and its impacts on natural and human systems in the Arctic. Streletskiy is the President Elect of the United Sates Permafrost Ass ...[Read More]

Image of the week — Making pancakes
It’s pitch black and twenty degrees below zero; so cold that the hairs in your nose freeze. The Arctic Ocean in autumn and winter is inhospitable for both humans and most scientific equipment. This means there are very few close-up observations of sea ice made during these times. Recently, rapidly declining coverage of sea ice in the Arctic Ocean due to warming climate and the impending likelihood ...[Read More]

Diving under the scientific iceberg
written by: Anne Voigtländer, Anna Schoch, Elisa Giaccone, Harry Sanders, Richard Mason, Johannes Buckel At the EGU General Assembly international researchers from all earth science communities gather and share their most recent endeavors. This year, we, a group of European young geomorphologists, tried a new session format to address challenges we all face in our research, ranging from inaccessib ...[Read More]

New faces for 2018 – 2019
We found some bright new faces at the EGU GA this year, so we need to make some introductions! Both the Early Career Scientist Team and the Blog Team have expanded and it is my absolute delight to introduce to you our 2(!) ECS Representatives for 2018-2019 and our new addition to the blog team (also see this post if you have forgotten the other members of the blog team)! ECS Representatives Nico S ...[Read More]

Image of the Week — Seasonal and regional considerations for Arctic sea ice changes
The Arctic sea ice is disappearing. There is no debate anymore. The problem is, we have so far been unable to model this disappearance correctly. And without correct simulations, we cannot project when the Arctic will become ice free. In this blog post, we explain why we want to know this in the first place, and present a fresh early-online release paper by Ingrid Onarheim and colleagues in Bergen ...[Read More]

Report from the 2018 EGU General Assembly
Last week the 2018 General Assembly were held in Vienna. Gathering 15 075 scientists from 106 countries, this is the most important EGU event throughout the year. Summarizing what happened during the week is an impossible task, as a meeting like this is way more than the 666 individual sessions convened and the 11 128 posters presented during the week. However, in this post I will point to some of ...[Read More]
