I'll have to pass this year sadly, but I joined 2 years ago and that was one of the best meeting I've ever attended! Sea ice from breakfast to dinner (and see nice people, also)

a flyer for a phd opportunity. the background is a save, the overlay text reads: PhD opportunity, Submesoscale ocean flows and processes in the Southern Ocean. Logos are at the bottom on a white background for: NERC GW4+. University of Exeter, and National Oceanography Centre

Currently a large outbreak of cold, Arctic air is making its way south over the Norwegian Sea. The amazing mesh structure (called open-cell convection) in the satellite image (coloured image) is really hard for weather forecast models (grey image) to get 'right' @bjerknes.uib.no #ISOSCAN_project

Proposal Writing Training and Idea Development for Early‐Career Researchers Based on Constructive Alignment, Co‐Creation and Active Learning Strategies We developed a novel concept for training in proposal writing, constructively aligning learning outcomes with students' needs, co-creating course content with teachers and students, and using active ....

🧪 🥳 Its not every day that a group of research advisers publish in a scientific journal!

Early career researchers need proposal writing skills. Therefore a new way of teaching proposal writing was developed. It is now accessible to the research community.

Fisheye photo of a massive green and red curtain of aurora taken from a pier next to a fjord. The pier can be seen in the lower right corner with some people on it and few trees to the right. The fjord and the land on the other side can be seen on the lower left part of the picture. Finally the aurora appears like a massive mountain of light rising from the sea to, almost, the top of the picture. It presents shades of green and yellow on its lower part, with the majority in bright to deep red. Finally, of strong reflection of the aurora appears on the sea in a curved lower band in the pic.

Last year on this day, we had what is so far the best aurora show I ever saw in Bergen... and by far! It was also the first night I could play with my new fisheye lens. I had a lot of fun! I am really looking f... Read more on Instagram: https://www.instagram.com/p/DPoS7dUAjM6/

By applying a tracking method to both climate models and satellite data, @davyclimate.bsky.social found that sea ice age is a more sensitive indicator of change than ice thickness or volume.

A Fair Assessment of Sea Ice Age Reduces Bias and Gives New Insight to Arctic Sea Ice Dynamics We applied the same algorithm for diagnosing sea ice age in observations to a climate model for the first time The derived sea ice age reproduces the model dynamics but has much lower bias compar...

We have a new paper out today taking a fresh look at sea ice age, showing how this variable offers new insights into Arctic climate change:

If you're interested in sea ice and how we can track its development, you may want to sign up for our 1-day seminar where we'll be talking about the breadth of ECVs for sea ice, new developments in tracking sea ice age, and the pitfalls and opportunities of climate model - observation comparisons.

Bar chart for Lisbon, Oslo, Paris, Rome, Vienna showing blue bars (tropical nights) vs orange bars (tropical 10 pms) in 2025 so far. Orange bars tower over blue in every city except Rome, highlighting bedtime heat.

🌡️ Not all hot nights are equal. We track “tropical nights” when temps never dip below 20 °C—but what if it’s already 20 °C at bedtime? I crunched ERA5 data for 5 European capitals. Let’s talk tropical 10 pm. 👇

Atlantification drives recent strengthening of the Arctic overturning circulation A less ice-covered Arctic shifts dense water formation northward, strengthening the Arctic Ocean overturning circulation.

Is a monster web of ocean currents headed for collapse? The race is on to find out Research ships rarely brave the Greenland Sea in winter. Early this year, scientists ventured into the ice-covered waters to capture crucial data about the planet’s future.

Searching for navigable seas and better ice predictions When Roald Amundsen planned his ship expedition to the North Pole, he saw no other option than sending his crew into the air to search for open leads.…

Means have changed, the aim is the same. Developing tools for navigation through sea ice requires creativity and technical skills, as shown by Anton Korosov and Artem Moiseev from @nansensenteret.bsky.social. 🌊 🧪

Not bad at all! neXtSIM was mostly designed to represent the deformations of pack Arctic sea ice, so we wanted to check which opportunities it could offer in the Antarctic. Our results suggest that neXtSIM does pretty well at capturing the ice response to storms in regions like the Weddell Sea. 2/3
