It is scary how fast the Greenland Ice Sheet is melting and how much freshwater it is discharging to the coastal areas around Greenland. This freshening is having a serious impact to coastal marine primary production, which is the foundation of the Arctic marine food web. Now, because of increased melting and freshwater discharge, we …[Read More]
When speaking about glaciers and the ice they contain, we generally picture large, clean, and therefore relatively white mountain glaciers… But did you know about rock glaciers? From our Image of the Week, you might notice that they do not quite look like the classic ice glacier you might have had in mind. Indeed, they …[Read More]

Our international team of 29 scientists and 2 science communicators, led by co-Chief Scientists Mike Weber and Maureen Raymo, is boarding the …[Read More]
Today’s Image of the Week shows meltwaters originating from Leverett Glacier pouring over a waterfall in southwest Greenland. We have previously reported on how meItwater is of interest to Glaciologist (e.g. here) but today we are going to delve into how and why Biologists also study these meltwaters and how the cryosphere interacts with biogeochemical …[Read More]
What is happening under a glacier? This is a difficult questions to answer as accessing the glacier bed is usually not that easy. Here, we are getting a rare glimpse of the different processes and materials that are often found at the ice-bed interface. The photograph shows both sediments and hard rock, clear ice and …[Read More]

Instead of sunshine and 25 degrees, the temperature was closer to the freezing point on the thermometer and normal summer weather was replaced by milder weather conditions. The destination of the …[Read More]
