Coffee break biogeosciences–high resolution δ18O record from bivalves

Rachael Moore December 9, 2016

Much like trees, clam shells have growth rings. The chemistry of these rings can be used as a proxy for ocean chemistry. Recently, an international team of scientists used the growth rings found in shells of Arctica islandica to produce an annual absolutely dated marine δ18O record for the last millennium which was published in Nature Communications. The record represents the first fine scale arch ...[Read More]

Minds over Methods: studying dike propagation in the lab

Stefano Urbani December 7, 2016

Have you ever thought of using gelatin in the lab to simulate the brittle-elastic properties of the Earth’s crust? Stefano Urbani, PhD student at the university Roma Tre (Italy), uses it for his analogue experiments, in which he studies the controlling factors on dike propagation in the Earth’s crust. Although we share this topic with our sister division ‘Geochemistry, Mineralogy ...[Read More]

Image of the Week – Sea Ice Floes!

Chris Horvat December 2, 2016

The polar regions are covered by a thin sheet of sea ice – frozen water that forms out of the same ocean water it floats on. Often, portrayals of Earth’s sea ice cover show it as a great, white, sheet. Looking more closely, however reveals the sea ice cover to be a varied and jumbled collection of floating pieces of ice, known as floes. The distribution and size of these floes is vitally imp ...[Read More]

Image of the Week – What an ice hole!

Céline Heuzé November 25, 2016

Over the summer, I got excited… the Weddell Polynya was seemingly re-opening! ”The what?” asked my new colleagues. So today, after brief mentions in past posts, it is time to explain what a polynya is. Put it simply, a polynya, from the Russian word for “ice hole”, is a hole in the sea-ice cover. That means that in the middle of winter, the sea ice locally and naturally opens and reveals the ocean ...[Read More]

Harsher than reviewer 2?

Laura Ermert November 18, 2016

Have you ever wanted a reviewer who really tells it how it is? You should consider submitting a paper to the truly special publication ‘Frontiers for young minds’. Frontiers for young minds is a journal for students between ages 8 and 15 that are curious and passionate about science. However, what’s truly special about this journal is that it is also reviewed by students of the same age, assisted ...[Read More]

Image of the Week – Goodness gracious, great balls of ice!

Emma C. Smith November 18, 2016

At first glance our image of the week may look like an ordinary stoney beach…but if you look more closely you will see that this beach is not, in fact, covered in stones or pebbles but balls of ice! We have written posts about many different weird and wonderful ice formations and phenomena (e.g. hair ice or ice tsunamis) here at the EGU Cryosphere blog and here is another one to add to the l ...[Read More]

Ice-Hot News : The “Oldest Ice” quest has begun

Oldest Ice PhD Students November 14, 2016

This is it! The new European horizon 2020 project on Oldest Ice has been launched and the teams are already heading out to the field, but what does “Old Ice” really mean? Where can we find it and why should we even care? This is what we (Marie, Olivier and Brice) will try to explain somewhat. Why do we care about old ice, ice cores and past climate? Unravelling past climate and how it responded to ...[Read More]
