On this September 13th, coinciding to be a “Friday 13th”, we wanted to scan the cryo-history for expeditions started, sunken ships that day, and mountain myths. And we did find that. But as autumn approaches in the Northern hemisphere, the spookiest story of all was this one: the unlucky timing of the Arctic sea ice …[Read More]
Let’s continue the journey of discovering cool facts about sea ice which started with breaking the ice. This time, we’re diving into a fascinating part of the Arctic and Antarctic: the Marginal Ice Zone (MIZ). Imagine a place where the vast, frozen world of sea ice meets the moving waters of the ocean underneath. This …[Read More]
In our blog, we have written a lot about Arctic sea ice (see this post, this post and this post for recent examples). Much less has been written about Antarctic sea ice, i.e. its southern counterpart. That is not surprising as Arctic sea ice has experienced major losses since the late 1970s (beginning of satellite …[Read More]
Most of the time when we speak or read about sea ice it is probably about its extent or thickness or the decline in both, or maybe even about the microorganisms living inside and underneath it. How sea ice breaks and deforms is normally not so much the topic of general discussions. This is …[Read More]
Do you think that it is sometimes challenging to understand science (as a reader or listener) or to explain it (as a scientist)? Then, art may be a good solution to the problem. Between April and June 2023, Zacharie Bodson (artist) and I (climate scientist) are participating in the Seas and Oceans exhibition to explain …[Read More]
What do you need to form sea ice? Well, you can start with some sea water, an ocean will do, and cold air above it. Once a layer of ice starts forming, break it to make some cracks. You would have not thought of that? Yet, our recent study suggests cracks in the ice contribute …[Read More]
Have you ever wondered what dark secrets the Arctic sea ice holds during the harsh winter months? Imagine total darkness in the central Arctic, making it almost impossible to gather scientific information. At this time of the year, usually only satellite observations are available. This changed in September 2019 when a team of scientists collected …[Read More]
In this post, I will talk about two famous characters of the climate system; I will define them and see how they have changed in the current context of climate change. I will also show you how these two characters interact, one influencing the other, and vice versa. Finally, let’s see how the future looks …[Read More]
There, what is this, spoke the sea ice algae. Is this the first light of dawn? Is it finally this time of the year again? Spring…the best time of the year…the BBQ season? And in the little brine pockets all around the sea ice, the bacterial and archaeal community stirred alive. BBQ? Did somebody mention …[Read More]
If you look at the maps in Figure 1, you will quickly see that sea ice is present in both polar regions (Arctic at the top, Antarctic at the bottom). Despite this apparent similarity, some differences exist between Arctic (in the Northern Hemisphere) and Antarctic (in the Southern Hemisphere) sea ice. We provide a brief …[Read More]
