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

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!

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.
