On Tuesday I talked about sea weed accumulating close to the sea wall in Kiel fjord, and I showed you the picture below.

One thing that I found really interesting about that is how the floating sea weed dampens out all the waves. You can see it in the image above, bit it might be easier to see in the picture below: Can you see how there are a lot of ripples near the top of the image and none close to the sea wall at the bottom of the image?

It’s not quite a surface film, yet its impact is the same.
