Turbulent wake watching

Yesterday I wrote about why a ship’s turbulent wake stays visible for such a long time after the ship has gone. Here just more pictures of the same phenomenon because apparently I cannot NOT take pictures of this kind of stuff.

Above: Very clearly very turbulent.

Below: Less energetic, but the large eddies still move a lot of water around and you very clearly see the border between the turbulent wake and the “normal” water around it.
