As I walked further along the beach from Hill End to Spaniard Rocks, I realised that there were maybe four or five strandlines lying parallel to each other and to the water line. Each line of mainly organic debris was slightly different in its constituents. Similarly, there were changes in the make up and proportions of the animal and plant debris in the strandlines in a linear way as I walked from south to north along the shore. The starfish became less numerous and the numbers of bivalve molluscs and their shells increased,
Most noticeable was the way in which the darker particle component of the strandlines became separated out on the up-shore side of the lines, and formed patterns contrasting with the yellow sand on which it lay. Sometimes there were branching lines of clear spaces, like rivulets running through the black stuff. Sometimes, the black pieces followed and echoed the shallow ripple marks in the sand – either as parallel lines or cross-hatching designs full of beautiful natural abstract compositions. In other places, small obstacles such as seashells had formed little dams to impede the flow of lighter, darker, material as the water that carried it swashed and backwashed over the beach, and this had created distinctive patterns as the water flowed around the barriers.
I was curious about what made up the fine black material responsible for the patterns. I took some samples to look at under the microscope when I got home.
There is nothing I like better than strolling along the seashore and looking not only at the view but in detail at all the rocks, shells, and seaweeds. I love the colours, patterns and textures. I am curious about what they are called and how they came to be there. What happened geologically to form the rocks, when did it happen, what processes have worn the rocks away to leave their present formations? The living organisms like the seaweeds, limpets and periwinkles are connected to the rocks as part of their habitat preferences. Birds live, feed and die around the seashore. Everything is inter-related and I am one with them all. The feeling of being a part of it all is hard to beat. I capture these moments with my camera and relive the experiences by looking at the photographs later. They lift my mood and make me feel happy. The pictures in this post record some of the sights and natural treasures that I discovered walking along the rocky shore at Rousse Point in the Channel Island of Guernsey. Enjoy.
