A summary from @belspo.be of the Belgian participation to the Ocean Optics XXVII conference @oceanopticsconf.bsky.social 🌊🧪 eo.belspo.be/en/news/ocea... I had the honour of giving the opening keynote on this wonderful theater, "The Art and Science of Interpolating Sparse Ocean Colour Observations"
A big theater room with several rows of red chairs, and lights around it.

Yesterday I gave a talk about oceanography and remote sensing to a group of teens and teachers. Always fun (and challenging!). I brought a small infrared camera and passed it along to explain those measurements, I think that's what they liked the most 😅. Here's a picture with part of the group 😀🌊🧪
an image in infrared of people sitting in an auditorium. Background and chairs are blue and people in yellow, red and white. We can recognize the faces as the white (warmest) parts in the image.

I think I found a meteorite in my nearby wood... like 2cm long, it's like it's been melted and it's magnetic, could it be a meteorite then?
A black rock lying on the brown-yellow  ground. It is smooth, it measures 2cm long and 1 cm wide.

Here's the scar left by the wildfire near my hometown 😔, seen by #Sentinel2 and using the false color visual in the Copernicus Browser.

For me, it is a bad idea that many scientists use the hype AI term (among others, because funding agencies ask for that!) instead of deep learning or machine learning, which describe more accurately what we do in most applications. And I think this will backlash at some point...

Europe’s seas are experiencing heat that would have been virtually impossible in a pre-industrial climate. In the Mediterranean, summer SSTs have intensified by 3°C, far exceeding global warming, destroying marine life & dramatically altering our seas. www.worldweatherattribution.org/climate-chan...

Sadly, in my hometown in Spain the sun is being "eclipsed" by smoke from a nearby wildfire... ☹️ An awful situation, I hope it gets controlled quickly.

It could get worse.
For David Ho, an oceanographer at the University of Hawaii, the effects of these decisions could be felt for several decades. "If the Trump administration makes further budget cuts in the global ocean observation program, he warns, "it will have disastrous consequences on our ability to accurately model the climate system and extreme weather events, as well as to provide data for maritime safety and ground verification of satellite data.

And today's submesoscale image: waves! Or their absence in the western part of the Bay of Calvi (Corsica) where #STARESO station is located. The Revellata peninsula creates a shade zone from waves coming from the Ligurian Sea. It must have been windy! #LiegeOcean26 🌊🧪 www.ocean-colloquium.uliege.be
A satellite image showing the ocean in blue and land in green-brown. Over most part of the ocean we can see wavy patterns but these are stopped within the bay by the presence of the Revellata peninsula in the western part of the bay. Image taken by Sentinel 2 on 12 May 2026.

ok here goes my image of today of small stuff happening in the ocean #LiegeOcean26. Here foam from phaeocystis blooms along the coast of Belgium, forming these thin white lines you see in the picture (you might need to zoom) 🌊🧪 And remember the Liège colloquium 😀 www.ocean-colloquium.uliege.be
Satellite image showing the ocean in blue-green and the land in the lower right corner in clear green. Thin white lines parallel to the coast are foam evidencing the presence of phaeocystis globosa. This foam is not toxic but it can accumulate in the coast/beach. Sentinel-2 image on 9 May 2026.
