What are those white spots on the sea

+0
−0

Yesterday I was flying above the Mediterranean sea, it was a nice day, without storms or strong winds. I fly around 20 minutes above it before arriving to the ground.

During these 20 minutes I saw that the sea had plenty of white spots, some of them really big, more than a ship. They were not changing size, changing shape or disappearing as waves would do. Really, each one of them did not change at all during the minutes I could see them.

It looks as foam from a chemical product or something similar. But there was A LOT of spots during long time in the whole sea, as far as I could see and during the whole travel. Close to the shore, the white spots disappear. What can that be? If is some chemical, where does it come from? Waves? I dont think so...

-I am not sure if I should ask this here-

See this photo I did. They seem at the beginning waves but they would change. These spots in the photo didn't change at all

I was flight through more or less this route:

They are wave crests. It's wind folding over the top of waves, which mixes them with air. They're also called white caps. If they're closer to the shore you have a change of water color to a lighter blue. That lighter blue could mean there's coral below or a shallow bottom. Waves do not move fast. They're more like a drum in the water slowly rolling forward, with the wind picking up the back side & folding it over the drum.
