Photographer's Note

The sea along the west coast of South Africa is very dangerous when storms driven by the north east winds occur. Certain parts of the coastline are more dangerous than others and in many areas you will find a lighthouse guarding the coastline. In between Cape Town and Shelley Point a distance of about a hundred and fifty kilometres you will find no fewer than eight lighthouses situated at various points along the coastline. Shelley Point is the most northerly lighthouse and fortunately does not have a history of shipwrecks on its doorstep. That is not to say that ships have not run aground in the area.

I took a series of shots at Shelley Point on an overcast and very windy day, even standing up was a challenge and there was little time to shoot off some frames without my lens being spattered by sea spume. In this shot you can see that the spume is being blown in across the sand.

According to Wikipedia sea spume is a type of foam created by the agitation of seawater, particularly when it contains higher concentrations of dissolved organic matter (including proteins, lignins, and lipids) 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 presence of these surfactants under these turbulent conditions traps air, forming persistent bubbles that stick to each other through surface tension. Due to its low density and persistence, foam can be blown by strong on-shore winds from the beach face inland.

I attach a WS shot which shows the 1920’s built Shelley Point light house under dull skies.
