Data from Cullercoats
1. The following data was collected from the rocky shore at Cullercoats. The
distribution of two species (toothed wrack and limpets) were analysed at three
positions using transects on the rocky shore and a quadrat. Replicates on each
transect were performed. The lower shore is closest to the sea and the upper
shore is farthest from the sea.
