Splash zone: seaweed zoning on Runswick beach.

At the top of the beach and the foot of the cliffs the rocks are wetted only at high tides, and often only at spring tides. This is the green seaweed of the splash zone at the foot of Kettleness cliffs. Coming next: a section down Runswick beach at lowtide looking at how the species of seaweeds change from high to low tide mark.
