Sep. 2025: (Sub)mesoscale helps in understanding oxygen concentration in the waters
Observation of small-scale processes and filamentation is important to better understand the distribution of biogeochemical properties and the stirring.
-
Aug. 2025: Filaments help in understanding a harmful algal bloom
Finite-size Lyapunov exponents (FSLEs) and Lagrangian advection of virtual particles from altimetry data, can be used to understand the physical mechanisms of the toxic algae concentration.

Jul. 2025: Altimetry measures close to the coasts of La Rochelle
Coastal altimetry is a complex topic a new dataset AltiCap provides Sea Level Anomalies "close" to the coasts. A study looks at La Rochelle neighborhood
-
June 2025: Forecasting Sargassum over the next season
A seasonal forecasting model for sargassum using observations has been developped, to better mitigate their stranding
-
May 2025: Waves trapped along the coasts monitored by altimetry, thanks to Swot (and others)
Now, combined nadir and Swot gridded altimetry data can be used to monitor coastally trapped waves - and probably other coastal phenomena with similar time frequencies
-
Apr 2025: Little eddy in a big ocean, seen by Swot
Swot instantaneous 2D sea surface height mapping over its swaths enables to detect more Sea Level Anomaly variability than previous multimission maps
-
Mar. 2025: Computing vertical mixing from Swot sea surface heights
Swot surface observations can be used to reconstruct the vertical dynamics of the ocean with greater details than even before
-
February 2025: A tidal bore visible in Swot data
Swot 1-day Calval orbit enabled to measure daily sea surface height in the Severn estuary at a moment when the tidal bore was present.

Jan. 2025: 30 years of sea ice for both Arctic and Antarctic Oceans
A homogeneous 30-year series (1994-2023) of sea ice thickness and volume variations over the two hemispheres has been reconstructed from altimetry by Legos
