NCAR is quite literally our global mothership. Everyone who works in climate and weather has passed through its doors and benefited from its incredible resources. Dismantling NCAR is like taking a sledgehammer to the keystone holding up our scientific understanding of the planet. Unbelievable.

L2A artifacts 😊

Your pretty picture of the day 😀 🌊with of course many interesting processes! Water rich in suspended sediments is moved around by ocean currents in the Bay of Biscay. I'm curious about the long-range waves seen in the dark region, can't decide if these are oceanic, atmospheric, or an artifact 😅

Another insane move from the Trump regime. One of NCAR's contributions to climate science is the development of the Community Earth System Model (CESM), which is used by researchers worldwide. Here's a simulation of air-sea CO₂ fluxes from CESM.

well, the little eddy north of Mallorca is still going strong after 2 weeks 🌊

Don’t miss the final CLIVAR webinars of 2025 as we wrap up the year! Dec 10: "Ocean-atmosphere coupled model development(...)" with Jing-Jia Luo (07:00 UTC) Dec 11: "When internal variability meets climate change(...)" with Thibault Guinaldo (14:00 UTC) Check the full details 👇

I made this compilation of some of my favourite demonstration videos from the last couple of years Which almost look like magic (to me at least). I hope you like it. #ITeachPhysics #SciTeachUK youtu.be/jQKr1ZrQSjc

We have launched the call for abstracts for the 2026 Liège Colloquium on Submesoscale processes! #LiegeOcean26 Please submit your abstract at www.ocean-colloquium.uliege.be Deadline 31 January 2026! 🌊🧪

Sea Surface Temperature in the western Mediterranean Sea, with a nice little warm eddy 🌀 north of Mallorca. It's been there for a couple of days, though it is dissipating quickly it seems. #DINEOF 🌊

Awesome picture! We have seen this at submesoscale features, where currents couple strongly to the short (and steep) waves as they travel at comparable speeds, leading to enhanced breaking depending on the orientation of the waves/currents. Here's a photo off the coast of California showing this.

Here's a view by #Sentinel-2 of the Rhone river plume within the Gulf of Lion waters. Other the change in water colour, and the strong front between the two water masses, I love how there are more wind-induced whitecaps in the bluer waters, although I do not have a direct explanation about it... 🧐🌊

Morning bike commute during fall is so beautiful 🍂🍃. It's also a bit of "find your way" 😄, the path is less visible by the day (there's supposedly a concrete path there)

ok, this is maybe a long shot, but anyone here using GPS tags (the ones you can put in luggage etc) for self-built surface drifters? 🌊 So far we've used raspberry-pi with a GPS module, but we have lots of connection problems, so we're looking to simplify this....

Oh, and now a circumzenital arc, combined with some thin cirrus #clouds... sky today is gorgeous 😍

A quite strong Sun hallo right now 🤩. I'd say there's a second line between the sun doing and the sun that I am not sure what it is 🤔

📣 🌊 Call for abstracts #EGU26 !!! Please consider our session: ITS1.9/OS4.1 Machine Learning for Ocean Science meetingorganizer.copernicus.org/EGU26/abstra... Deadline 15 January 2026 (1 December for travel grant applications) @brajard.bsky.social @rachelfurner.bsky.social @redouanelg.bsky.social

Spooky story about NASA GSFC - story about destruction of NASA's center that is happening under the shadow of the shutdown. www.space.com/space-explor...

There are more than 100 marine research institutions in the United States and they’re under threat from Trump’s attack on science funding. 🌊

Alboran Sea surface temperature still looking great 🌊

Each day is different here, sunny day ahead, with some fog around Calvi this morning #STARESO

Now that it is raining I have time to complain about the difficulties with the Aanderaa software, such a pain. You need a windows computer, but windows 11 doesn't work. I found an older version, but still no luck, connection errors, how are we supposed to work with this software?.... 🌊

This little one wanted to hitch a ride 😄🌊🐙

We got two ADCPs deployed today in the Bay of Calvi, thanks to the help of the great #STARESO staff 🙏🌊. Now let's wait for the data!

Insane. This is Hurricane #Melissa seen right near landfall by the Copernicus / @esa.int Sentinel-2C satellite. It looks so beautiful, and it's hard to comprehend how much destruction a hurricane like this can cause. Best wishes to everyone in Jamaica.

The bay of Follonica, in Italy, always displays great patterns when waters rich in suspended sediments enter the bay 🤩. This time, with high winds in the western part of the image, which I guess play a role in the patterns within the bay 🌊 #sentinel2

#Melissa has become a Category 4 Hurricane. Its eye feature is clearly visible with infrared satellite and rain radar. Jamaica: Seek shelter now.

A cool sea surface temperature pattern in the Alboran Sea, seen yesterday by #Sentinel3. We have the typical Alboran gyre, being squeezed by warmer water coming from the northwestern Mediterranean. Cold upwelled waters along the Spanish coast are getting trapped between the two warm water masses 🤩🌊

The incredible tragedy for #ArcticScience of NOAA shutting down their #methane monitoring data. 5th May 2025 is the last data we'll ever get. #NCKF25

Yesterday, Cécile Pujol of the GHER @universitedeliege.bsky.social successfully defended her PhD thesis on the study of Marine Heatwaves and Cold Spells in the Pataginian fjords. I couldn't be prouder!! She's done an amazing job, and I wish her the best in her career 👩‍🎓🌊

Heading to #STARESO station next week, in Corsica, to keep up with some of the data collected there and to prepare to next year's student research stay. Looking forward to the immense blue of the Mediterranean 😀🌊

🌊 a chance to learn how to use a whole pile of amazing NASA Earthdata tools in cloud.

There's a 23cm diameter Amanita muscaria in my garden, and seeing it grow has been the highlight of the week 😅. It started like a small ball with not huge aspirations...

Featuring a Desertas petrel that stunned scientists by chasing a tropical storm (see their incredible chase mapped here!), tiny nightingales that cross the Sahara twice a year, and Bewick's swans that have changed their stopovers and diet

Very nice graphics, especially the one showing a petrel following a tropical storm's wake, probably for feeding on the cold upwelled waters 😮🌊🌀

Open Ocean #11 Playing whack-a-mole with some interesting artefacts in the data and interpolation. diagrammonkey.wordpress.com/2025/10/09/o...

A curious reddening pattern in these aspen leaves 🧐

Like a canary in coal mine…

Simply beautiful photos of climate scientists in action. And really well explained - worth a read. 1/

The dance of titans has started in the North Atlantic with hurricane Imelda and hurricane Humberto 🧵!

In discussion with a computer scientist from the University of Cambridge last night: Me: "you've described some of the things that AI is good at. How would you describe the category of things it's not good at? **pause** Him: "Anything where it has to be right".

A cloud radar in space that can also get ocean echoes? WIVERN is selected for @esaearth.esa.int EE11! OK, I did have a different proposal for EE11 called STREAM ... and I also got involved in the EE11 proposal SEASTAR... so this is really not optimized for currents www.esa.int/Applications...

A swirl with an eye and a nose? Nope, not weather—just river sediment in Yana Bay, seen by Sentinel-2. Nature sketches its own cartoons in one of the Arctic’s remotest deltas. Explore the full story in our new #BCEarthGallery article! #Sentinel2 #YanaBay #LaptevSea #Arctic 👉 bit.ly/4n6ne67

Sediment plumes like this form when rivers carry fine particles into the sea. Currents then swirl them into vortices, reshaping coastlines, altering ecosystems, and even affecting how sunlight penetrates the ocean surface.🟢🌀 @aida-alvera.bsky.social 🌊
