New blog!

New blog!

We are very happy to announce that from now on, also the Tectonics and Structural Geology division will have its own EGU blog! With this blog we would like to provide a platform for exchanging thoughts and ideas within the global tectonics and structural geology community. Here, we will write, on a monthly or fortnightly basis, about topics or techniques addressed by the many research groups that ...[Read More]

Image of the Week – How ocean tides affect ice flow

Image of the Week – How ocean tides affect ice flow

Ice streams discharge approximately 90% of the Antarctic ice onto ice shelves , and ultimately into the sea into the sea (Bamber et al., 2000; Rignot et al., 2011). Whilst flow-speed changes on annual timescales are frequently discussed, we consider here what happens on much shorter timescales! Previous studies have shown that ice streams can respond to ocean tides at distances up to 100km inland ...[Read More]

Coffee break biogeosciences–The oldest known fossilized active root meristem

Coffee break biogeosciences–The oldest known fossilized active root meristem

Meristems are groups of undifferentiated cells found in growth zones of plants. Active meristem zones have a different cellular organization than inactive zones, and up until recently no fossilized active root meristem had been found. A team of scientists recently found and described the fossilized remains of an actively growing root meristem dating from the Carboniferous. The fossil, named Radix ...[Read More]

MyShake – your phone as a seismic station

MyShake – your phone as a seismic station

Are you on Facebook or Twitter? Do you use Whatsapp regularly to communicate with friends and loved ones scattered across the globe or even just across the city? I’d be surprised if you answer ‘no’ to all of these questions. In fact, why not admit that you are just as addicted to that smartphone of yours as I am to mine? Being a seismologist, you might have played with one of the ...[Read More]

Image of The Week – A Game of Drones (Part 1: A Debris-Covered Glacier)

What are debris-covered glaciers? Many alpine glaciers are covered with a layer of surface debris (rock and sediment), which is sourced primarily from glacier headwalls and valley flanks. So-called ‘debris-covered glaciers’ are found in most glacierized regions, with concentrations in the European Alps, the Caucasus, Hindu-Kush-Himalaya, Karakoram and Tien Shan, the Andes, and Alaska and the weste ...[Read More]

A tale about MERMAIDs

Once upon a time there was a little mermaid, with the upper body of a human and a tail of a fish, happily diving within the seven seas. Wait … I’m sorry, that is the wrong story. I will tell you today something about a different generation of MERMAIDs, that are pretty useful for seismologists. It is a very exciting story indeed.   Over the last decades seismic station coverage dra ...[Read More]

Image of the Week – Canyons Under The Greenland Ice Sheet!

Image of the Week – Canyons Under The Greenland Ice Sheet!

The Greenland Ice Sheet contains enough water to raise sea level by 7.36 meters (Bamber, et. al. 2013) and much of this moves from the interior of the continent into the oceans via Jakobshavn Isbræ – Greenland’s fastest flowing outlet glacier. An ancient river basin hidden beneath the Greenland Ice Sheet, discovered by researchers at the University of Bristol, may help explain the loca ...[Read More]

Marine Ice Sheet Instability “For Dummies”

Marine Ice Sheet Instability “For Dummies”

MISI is a term that is often thrown into dicussions and papers which talk about the contribution of Antarctica to sea-level rise but what does it actually mean and why do we care about it? MISI stands for Marine Ice Sheet Instability. In this article, we are going to attempt to explain this term to you and also show you why it is so important. Background The Antarctic Ice Sheet represents the larg ...[Read More]

Paper of the Month — the first of a (hopefully) long series!

“TRIANGULAR DISLOCATION: AN ANALYTICAL, ARTIFACT-FREE SOLUTION” (by Mehdi Nikkhoo and Thomas R. Walter) COMMENTED BY OLAF ZIELKE “Paper of the Month” is a new blog series launched by the ECS-reps team. The aim is to absorb and share the reading experience of mature seismologists with regards to peer-review articles either recently published (less than 12 months) or older, if of particular no ...[Read More]
