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

A seasonal forecasting model for sargassum using observations has been developped, to better mitigate their stranding

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

Swot instantaneous 2D sea surface height mapping over its swaths enables to detect more Sea Level Anomaly variability than previous multimission maps

Swot surface observations can be used to reconstruct the vertical dynamics of the ocean with greater details than even before

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.

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
