We know that climate change is affecting many aspects of what we have considered “stable” throughout a long period of modern times. One of many impacted and changing factors is snow and thereby also snow meltwater. One way to study meltwater is to trace it by the usage of stable water isotope signals and we …[Read More]
Glaciers are mostly made of water. Sometimes, perhaps more than we’d like, some of that water makes a break for it by melting, the inconstant molecule… It might pootle around on the surface of the glacier a bit and get a lot of remote sensers very excited, but it’s what it does once it gets …[Read More]
Hidden below the surface of some glaciers, liquid water can be found within what is called the firn layer – the upper layer of a glacier where snow compacts into glacier ice. Liquid water may persist there for up to many years, forming what scientists call “firn aquifers.” While observations of seasonal firn aquifers have …[Read More]
In July 2017, the world’s largest iceberg known as A68 calved from the Larsen C Ice Shelf, located in the western Weddell Sea, Antarctica. Since then, A68 has lost two chunks of ice, A68-B and A68-C, but still remains a giant after more than 3 years. How did it feel to be the greatest, A68? …[Read More]
As Christmas gets closer, days are getting shorter in the northern hemisphere. A good excuse to get cosy inside on the sofa, drinking tea and eating Christmas biscuits. Meanwhile, a few thousand of scientists are heading “South”, to Antarctica, where the lengthening days provide the perfect conditions to conduct a whole variety of scientific field …[Read More]
5th August 2015, 10:30 in the morning. The meeting had to be interrupted to take this picture. We were aboard the Swedish icebreaker Oden, and were now closer than anyone before to the terminus of Petermann Glacier in northwestern Greenland. But we had not travelled that far just for pictures… Petermann’s ice tongue Petermann is …[Read More]
