The visualization tool for wave heights is just in time for my classes on waves starting in November!

fingers of higer waves are caused by refraction of swell over currents.The first time we saw this kind of feature was on Envisat ASAR.

The cyclone season has begun with Erin, now a tropical storm. TS Erin generated high swells along the U.S. coast and will bring big waves to European water. Have a look at the storm using 12um IR channel of @esa.int #Copernicus Sentinel3 SLSTR sensor on the #OVL portal

Once open from melting, this year, the NW Passage is chocked with ice. The #OneOceanExpedition on board the Statsraad Lehmkuhl had to turn back.
@esa.int #Sentinel1 SAR observations highlight this climate change around Arctic. Browse more on #OVL #seashotoftheweek:

🌊 @oceandatalab.bsky.social added more data to their "SWOT explorer": July 2024 at 250 m resolution is in. And this is the last day, August 1, with some very nice swell scattering between Java and Bali. Does this underwater shoal has a name? odl.bzh/8z6noOP_

Excited to be at @esa.int #LPS25 showcasing the #oceanvirtuallab. Come meet us at the EO Arena, we will demo the #OVL portal at 10:30 today and SEAScope viewer tomorrow at 09:45

I was looking at SWOT ocean data using @oceandatalab.bsky.social great OVL tool ... when I noticed some funny pixels on land... and zooming it happens to be clear cutting patterns in the Oregon forests. I'm curious to know more about forestry management in that area!

During the @esa.int #OTC25, we were blessed with a huge chlorophyll bloom North of Iceland. Many stations done in the area, including one in a Fjord. On #Sentinel3 OLCI L2 Chl, out of range values have been flagged as 'failed'. Have a look at #OVL #seashotoftheweek: seashot.odl.bzh/s/l97sfl7N8Ds

Station in the center of the Lofoten Eddy during @esa.int #OTC25 where very deep mixed layer is expected: CTD cast + BGC Argo float deployed that day. Wave drifters trajectories reveals location of this large anticyclonic eddy.

First station during @esa.int #OTC25 with CTDs, deployment of manta trawls and buoys! Even if the bloom is not fully develop, we hope to see interesting variability revealed by Copernicus #Sentinel3 OLCI Chl-a. All went well!

And off they sailed! Last photo of our students before they started the journey. I keep looking at the position of the ship, here's yesterday with #Sentinel1 data and geostrophic currents, from @oceandatalab.bsky.social

The one ocean expedition has started. The St. Lehmkuhl is heading to Tromso to embark students from @esa.int Ocean Training Course 2025. You can follow the ship on #OVL portal by selecting today’s date in calendar: odl.bzh/0pe1SoFc

I was looking again at these fantastic Sentinel 2 images over sea ice. I know nothing about ice rheology but the patterns of the fractures in the ice are fascinating. I can't help thinking there is an ocean eddy in the middle of this image, dragging the ice around.

Happy new year! The atmospheric front visible in #Sentinel1 SAR and @copernicusecmwf.bsky.social analyzed wind is typical of North Atlantic storm and brought us nice wind & waves to celebrate the new year with joy. Have a look at #OVL #seashotoftheweek: seashot.odl.bzh/s/wPbCZdaIdsI

Nature is amazing . I was looking for MIZ features, and I found this vortex street ... and lee waves . odl.bzh/jRvRtgH2

More cool pics of waves in ice and around icebergs ... 🌊

Large waves encountered by #VG2024 #vendeeglobe skippers these past few days. More than 8m SWH was observed by #Copernicus altimeters. The large waves and their propagation were well predicted by #MeteoFrance MFWAM model. More information at

Hi Bluesky! To celebrate our new account, we’re excited to share a stunning 10-day animation of a cyclonic-anticyclonic eddy pair, captured beautifully by Chlorophyll-a data from @ESA_EO @CopernicusEU. 🌊✨ #Sentinel3 #OLCI. More information at #OVL #seashotoftheweek: seashot.odl.bzh/s/p7gjMzi8Rgc
