The ruins of a hidden majestic city as Machupicchu in Peru immediately call for our attention. However, there are far more beautiful attractions found hidden amongst the landscape, such as the glaciers, high mountains or the cultural heritage in the area. In South America, glacial bodies are geographically restricted to the Andes, the mountain range that runs across the continent from the tropics ...[Read More]

The Sassy Scientist – Video Versatility
Lis has been studying, investigating, deconvoluting, cross-correlating, referencing, inverting, plotting, database searching … and whatnot. With just a few synapses still firing at all cylinders and demonstrating an uninterrupted dispense of productivity, she wonders: Should I start my own (geodynamics…?) online video channel? Dear Lis, Why not? Everyone’s not working properly anyways in this day- ...[Read More]

#vEGU21: #EGUartKIDS Hall of Fame – Extreme e-ART-h!
The EGU Kids Art activity normally happens in person in the creche at the conference centre during the General Assembly, but first last year and now this year we have had to move all our activities online instead. Working together – two of our Division Early Career Scientist teams, one from Natural Hazards and one from Cryospheric Sciences came up with this year’s theme ‘Extreme ...[Read More]

Cybersecurity at work
In this weeks Wit & Wisdom, revisit some cybersecurity 101 nuggets! We are not even half-way through 2021 and I can list more than a handful of occasions where my cyber-safety, both private and professional, was jeopardised (that I have been made aware of, the actual number is probably much higher). The Dutch research council was hacked1 (ransomware; documents leaked after refusal to pay; fund ...[Read More]

TS Must-Read – Platt (1986): Dynamics of orogenic wedges and the uplift of high-pressure metamorphic rocks
Orogens are the locus of intense deformation and metamorphism, mainly caused by convergent tectonics and burial. Yet, deeply buried rocks – metamorphosed at high pressure (HP) – are customarily met at the surface, even in “recent” systems such as the Alps. The long-standing question is naturally “how are these rocks brought back to the surface?” At the time John Platt wrote his manuscr ...[Read More]

Imaggeo On Monday: Tides at Young Sound
The work of the autumn tides at Young Sound, Northeast Greenland, created a fine sand artwork just before the freezing in of the fjord with the approaching winter. Due to the changing sediment of the nearby Zackenberg river, the local coastal erosion is an object of great recent investigations. Description by Maria Scheel, after the description on imaggeo.egu.eu. Imaggeo is the EGU’s ...[Read More]

The “Cliffs Notes” on Ice-Cliff Failure
The retreat of large glaciers that drain the Greenland and Antarctic ice sheets could expose immense ice-cliffs at newly-bared calving faces, which are the exposed ends of glaciers where, in these cases, glacier ice meets the ocean. Past a certain height, these ice cliffs will become susceptible to collapsing from high stresses, a process known as structural ice-cliff failure. If a taller ice clif ...[Read More]

Meet the new ECS Reps
We all hope you have enjoyed vEGU21 and you were able to meet new and old friends/colleagues/peers. With the end of the EGU General Assembly, it is the time when outgoing Early Career Scientist (ECS) Representatives (Reps) are handing all over to the incoming ECS Reps. Now the new Reps officially start their work for the next two years. But who are the new ECS reps? The new Rep for the next year i ...[Read More]

Happy Birthday Mama Etna!
18 May 1971. This date may not mean anything to you at the moment, but it represents a very special day for the evolution of Mount Etna, leaving a deep mark in the recent eruptive activity of the volcano. Exactly 50 years ago, Mount Etna saw the birth of what, only a short time later, was to become the most active crater of the last decades: “The South-East Crater”, the fourth child of ...[Read More]

Whole solid-Earth numerical simulation: Towards an understanding of mantle-core interactive dynamics
Due to huge difference between the time scale of the mantle convection and the outer core convection, they are modelled separately. In this week’s News and Views, Masaki Yoshida from the Volcanoes and Earth’s Interior Research Center, Japan Agency for Marine-Earth Science and Technology (JAMSTEC), Japan, put forward the recent development on the modeling of the whole solid-Earth. The E ...[Read More]
