Sea Foam - Harbinger of Change
Sea foam blown onto Druridge Bay beach, Northumberland, by a strong onshore wind.
I've never seen anything like this amount of the stuff before. While it's a novel thing to see, and kind of fun to watch dogs play in, it's disturbing to find that it may be a harbinger of changes afoot in the North Sea and in the global climate.
The foam is formed (according to the site below) by a micro-organism called phaeocystis. With excessive nutrients, it blooms out of control and forms large gelatinous blobs. When whipped up by wind and waves, they become sea foam. The blooms also produce a volatile sulphur compound that contributes to climate change.
