Stuff on trees, stuff on the beach ...


In bright sunshine and approaching high tide, I was out and about this afternoon at Rissers and the Islands admiring some of nature's creations …












Sea foam, something I didn’t know courtesy of Wikipedia ~
Sea foam is a type of foam created by the agitation of seawater, particularly when it contains higher concentrations of dissolved organic matter derived from sources such as the offshore breakdown of algal blooms. These compounds can act as surfactants or foaming agents. As the seawater is churned by breaking waves in the surf zone adjacent to the shore, the surfactants under these turbulent conditions trap air, forming persistent bubbles that stick to each other through surface tension.
