Zig Zag

Does anyone know what causes this strange zig-zag pattern on the sea? Definitely not reefs and hardly any wind to mention. I have never seen this before. Very pretty though.

Edit: Thanks to the clever research of Canadian Sue Slaght this phenomenon could be Langmuir circulation. Thanks Sue!

Other phenomena that have been easy to see on these glassy seas are the parallel lines of Langmuir circulation. They resemble corresponding paths of dark and light lines on the ocean’s surface that linger up and down the coastline. They can be easily seen from a boat or the shoreline.

  1. We have no idea and yes, it looks very pretty in your lovely capture. Siri and Selma are off to ask their friends, the mermaids. They could be involved in this. If a cooling wind passes by at yours today, could you please pass it on to us in Bonn. 35° ☀️☀️☀️ no fun at all, phew.
