The softness of ice, how we measure it, and why it matters for sea level rise

The softness of ice, how we measure it, and why it matters for sea level rise

One of the first things school children learn is that ice is a solid, and forms by freezing water. Most people think of ice as brittle–have you ever dropped a slippery ice cube on the kitchen floor, and watch it break and shatter into many pieces? It may be surprising, then, to find that ice can also stretch and squeeze, like a ball of pizza dough! Once deformed, ice is then softer in certai ...[Read More]

The Sassy Scientist – Printing: Pre- or Post-?

The Sassy Scientist – Printing: Pre- or Post-?

Giusy is throwing some deep dives into the trenches of scientific literature. Deep they are indeed. Almost running out of oxygen whilst frantically flapping through the murky waters near the surface, she comes across a not-yet-published paper (or better: a non-peer-reviewed paper) that’s floating around the internet. Apparently well-written and soundly researched, she goes looking for more a ...[Read More]

TS Must-read – Dewey (1988) Extensional collapse of orogens

After building orogens with Dewey and Bird (1970) and extending them during building with Platt (1986), Dewey (1988) explores the lifetime of orogens in their last breath: their extensional collapse. Simple considerations on how to form a normally-thick continental crust (30-40 km) from a thickened continental domain (50-60 km) indicate that erosion of the topography alone is far from being suffic ...[Read More]

Connecting the Networks for a better Understanding of the Ocean

Connecting the Networks for a better Understanding of the Ocean

Research in many scientific disciplines can be done singlehandedly by learning from the printed pages, solving complex equations and analyzing the data while sitting alone in an office. But observational ocean science research demands an involved team effort to get meaningful insights of the ocean. This is primarily because: The Ocean is vast – it is humanly impossible for anyone to conduct resear ...[Read More]

Meet the new Geodesy Science Officer – Part 2

In the past weeks you have met the president, deputy president and one science officer of the Geodesy division. Last but not least, we introduce you today to the second science officer: Xavier Collilieux. He also answered a few questions for us (including where his favourite place in Vienna is). Curious to find out? Then read below.   What is your position within the EGU and/or the Geodesy Di ...[Read More]

Earthquakes within the plates

Earthquakes within the plates

As fascinating as the plate tectonics and its accompanying dynamics are, continental interiors are no quiescent zones. The tectonics within these interiors are apparent in the occurrence of numerous intraplate earthquakes, and this week, EGU blog editor Arushi Saxena briefly discusses them and their mechanisms. Earthquakes are a fairly common occurrence here on Earth’s crust. Although most are ess ...[Read More]

Features from the Field: Stretching Lineations

Deep beneath our feet, deformation of rocks at high temperature produces impressive structures such as shear zones, that localize the movement of two volumes of rock with respect to one another. Shear zones are strongly deformed bands with strongly foliated structures (i.e., with rocks that look like a pile of leaves) and kinematic indicators, such as S-C fabrics, that tell us geologists which way ...[Read More]

The Sassy Scientist – The Secret Art Of Keeping Up-To-Date

It’s easy to feel overwhelmed by the impressive speed at which new science is published. How to keep up with all this is an art that few have mastered. Rami is looking for some pointers: Which are the must-follow journals to keep up to date with new geodynamic research? Dear Rami, Carefully checking the table of contents of freshly printed issues of your favourite journals is obviously the most mo ...[Read More]

The Norwegian Polar Institute

It is a pleasure for the EGU Cryoblog team to present a new post category: Cryo-institutes around the world! There are many institutes working on cryosphere-related research spread around the world. The aim of this new category is to highlight the cool research that is carried out at these institutes, showing off our multi-faceted cryo-related science. In this opening post, Ashley Morris will pres ...[Read More]
