On the Brunt Ice Shelf, Antarctica, a never-observed-before migration has just begun. As the pale summer sun allows the slow ballet of the supply vessels to restart, men and machines alike must make the most of the short clement season. It is time. At last, the Halley VI research station is on the move! Halley, …[Read More]

Ice Cores “For Dummies”
Ice cores are important tools for investigating past climate as they are effectively a continuous record of snowfall, which preserves historical information about climate conditions and atmospheric gas composition. In this new “For Dummies” post, we discuss the history and importance of ice-core science, and look at the way we can use ice core chemistry …[Read More]
Image of the Week – Blood Falls!
If glaciers could speak, you might imagine them saying – “HELP!” The planet continues to warm and this means glaciers continue to shrink. Our new image of the week shows a glacier that appears to be making this point in a rather dramatic and gruesome way – it appears to be bleeding! If you went to …[Read More]
Coffee break biogeosciences–high resolution δ18O record from bivalves
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 …[Read More]
Minds over Methods: studying dike propagation in the lab
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 …[Read More]
Image of the Week – Sea Ice Floes!
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 …[Read More]
Introducing the people behind the TS division

We are always happy to hear new ideas and feedback! Just drop a message on ts@egu.eu and don’t forget to stop by the division meeting during the General Assembly …[Read More]
Image of the Week – What an ice hole!
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 …[Read More]
Harsher than reviewer 2?
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 …[Read More]
Image of the Week – Goodness gracious, great balls of ice!
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 …[Read More]
