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]
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]
“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]
A curious experiment is taking place in Greenland. An experiment involving very large balloons and – of course – a lot of snow. Read on to discover why balloons are an environmentally friendly tool when constructing an ice core drill camp. Last year, a small team traversed 400km from northwest Greenland to the EastGRIP site (read more about the traverse here). This year another strenuous task is w ...[Read More]
Few places in the world conjure up images of remoteness and harshness like Far Eastern Siberia. Yet, it’s places like these where our science is needed most. Arctic soils hold vast amount of carbon, protected in thick layers of permafrost, but these stores are becoming more and more vulnerable as temperatures in the Arctic warm, and are set to warm faster than anywhere else on the planet. R ...[Read More]
One of the most dramatic signals of Earth’s recent warming has been the precipitous decline of the Arctic sea ice. While the sea-ice decline is in response to warming ocean and atmosphere, it also has an important feed-back on the climate itself. Solar radiation and albedo Earth’s main energy source is solar radiation. This solar radiation is either absorbed in the atmosphere or at the ...[Read More]
– written by Solmaz Mohadjer – Does contaminated soil make your bones go soft? What if you are told to stop growing vegetables in your garden because the soil is too toxic? What if farmers refuse to produce nutritionally valuable crops because of risk of massive floods? What would you do if you are forced to leave your farm due to fear of floods? Surprisingly, these are the kinds of q ...[Read More]
Working in the Arctic and Antarctic presents its own challenges. It is perhaps easy to imagine how a station situated close to the coast is resupplied: during the summer, one or more ships will arrive bringing fuel, food and equipment, but what about stations inland? Flying in supplies by aircraft is expensive and, in the case of large quantities of fuel, unsustainable. Besides, many stations are ...[Read More]
When you go down to the woods today you’re in for a big surprise….. hair ice! Did you know that there is a type of ice called hair ice? It is shaped like fine, silky hairs and looks like white candy floss. It grows on the rotten branches of broad-leaf trees during humid winter nights when the air temperature drops slightly below 0°C. A 100-year-old theory states that hair ice a ...[Read More]
EGU’s Pico’s (Presenting Interactive COntent®) are awesome and a lot of fun!! But at this year’s EGU General Assembly there was no Seismology PICO lead session. How sad was this? Why would this be? Can we do anything to change this? But wait, how much do you actually know on presenting or preparing a PICO…? Right, just what we thought… Perhaps not that much. There are many benefi ...[Read More]
