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)

PhD Opportunity! 🚨 Working with Dr Pauline Tedesco on "Submesoscale ocean flows and processes in the Southern Ocean." NERC GW4+ DTP PhD studentship for September 2026. DEADLINE: 8th Jan 2026 Find out more - www.exeter.ac.uk/study/fundin... 🌊🌐🌍🦑🧪 #PhDsky #AcademicSky

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

🧪 🥳 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. onlinelibrary.wiley.com/doi/10.1002/...

It’s been a while since I shared these, so here we go! If you are new to BlueSky, here are a few 🌊 ocean starter packs 🌊 to help you find who to follow: Physical oceanography go.bsky.app/Eb6xX19 Polar oceans go.bsky.app/851nQgx Organisations go.bsky.app/U1Ei6XY

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. 🧪🌊 Read the publication here: agupubs.onlinelibrary.wiley.com/doi/epdf/10....

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: A Fair Assessment of Sea Ice Age Reduces Bias and Gives New Insight to Arctic Sea Ice Dynamics agupubs.onlinelibrary.wiley.com/doi/10.1029/...

In the Arctic, sea ice has a leading impact on ocean surface dynamics, mainly in the regions that are seasonally ice-covered. Supply et al., examine the seasonal cycle of the ocean surface conditions in the seasonal ice zone 🌊 agupubs.onlinelibrary.wiley.com/doi/10.1029/...

🌊There is an available position as a postdoc at NORCE in ocean biochemical modelling fixed for a period of 2 years in Bergen. The position will be affiliated with the Bjerknes Centre and is a part of OceanICU project. 🧪Read more and apply here: www.jobbnorge.no/en/available...

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.

🌡️ 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. 👇

The Arctic Ocean acts to stabilize the AMOC New paper in #ScienceAdvances by researchers from @bjerknes.uib.no and @oxuniearthsci.bsky.social showing how ongoing Atlantification and sea ice loss leads to a strengthening of the Arctic overturning circulation. www.science.org/doi/10.1126/...

This ship braved the Greenland Sea in winter, venturing into ice-covered waters to capture crucial data about the Earth's future https://go.nature.com/4ebFOGj

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. 🌊 🧪

En forløper for satellitter? Kollegene mine ved @nansensenteret.bsky.social og @bjerknes.uib.no har andre verktøy, men deler Amundsens mål: å gjøre det lettere å navigere i tettpakket is.

Les visiteurs du soir.

After years of saying "it wouldbe fun", we did it! We cycled from home to Solstrand (34km) for our annual internal seminar at @nansensenteret.bsky.social ! A lovely morning ride in the rising sun despite the freezing toes.

Interested in recent changes in #Antarctica and the ocean around it? Our @oceaniceeu.bsky.social #climateCoffee series with ECRA continues on 16th April with this presentation from David Chandler. Now with correct link: www.eventbrite.dk/e/warming-of...

🆕 from PolarRES' @raphaelkoehler.bsky.social & colleagues on the future of the Beaufort Gyre, a major Arctic Ocean current. By accumulating/releasing freshwater, it shapes ocean properties. But most CMIP6 models project it will weaken or vanish, disrupting ocean circulation. 🔗: bit.ly/4cdZo3m

If you are into modeling of sea ice physical properties (salinity, brine volume, or density), we combined coring datasets to have a seasonal evolution for first- and second-year level ice: doi.org/10.5281/zeno... The coring datasets have many more parameters, including isotopes and nutrients.

📚 New paper alert! 🧵 agupubs.onlinelibrary.wiley.com/doi/10.1029/... 🧪 We present a unique dataset of 465 (!) in situ measurements of the #water_isotopes in vapor up to 1500m above the #Greenland Ice Sheet. 🌍 We demonstrate the use of water isotope profiles to reveal gaps in climate model physics.

🌊 Winds can make very big waves but very often nobody is there to see them in their full height. However, we do get swells radiated from these. I've just published two datasets about very big wave heights here: www.seanoe.org/data/00940/1.... www.seanoe.org/data/00942/1... next one: wave periods

📣 New preprint out for discussion! 🤓

We demonstrate that the eddy covariance method is reliable for measuring #turbulence over the #Greenland Ice Sheet in summer!

If you're looking for an alternative to PIOMAS when it comes to sea ice thickness, I recommend this dataset by my colleagues at the Nansen Center!

First time I *really* needed those this winter. Fun ride to work!

Back from a wave-ice workshop in Oslo, but Bergen had decided to keep me in the mood this morning.

Hello world! We'll be sharing insights, updates and visuals from our research about the fascinating world of remote sensing of polar regions right here in this place of Rayleigh scattering (aka Bluesky). Sea ice lovers, satellite enthusiasts, cloud admirers, snow fans, science nerds: let us connect!

Nice discussion in Eos about an article recently published in Nature Geosciences. Less sea ice ridges in the Arctic will have a lot of consequences on the environment. It should also strongly impact momentum transfer between the atmosphere and ocean 1/2 eos.org/articles/arc...

Currently at Geilo station, waiting for the Oslo train to bring me to my first wave-ice interactions workshop🌊❄️, ~10y after starting my PhD on this topic! Decided to spend 2 nights here beforehand, to warm up for it (sure, by -10degC, but well... Snow in the sun is another kind of warmth)

Aaaah Vestland... Days of rain and darkness, and as I start questioning our relationship, you offer me the most wonderful winter wonderland in the most mesmerising lights.

🌊The Norwegian Research Council chose to highlight our project iMelt (led by amazing L. de Steur at NP) as a "success story"! Unfortunately, the article is only in Norwegian, but there are nice photos! www.forskningsradet.no/suksesshisto...

On that grim day for sciences (and for about everything else I believe in), I've spent my work time procras... making a new animation to introduce waves-in-ice modelling. Here is the result! 🌊❄️
