Site Description: The transect site is situated across the intertidal rapids which are formed by the presence of hard rock outcrops with a narrow channel connecting Strangford Lough and a tidal lake. The rapids are split into three flows at ebb tide - two extremely fast, becoming waterfalls at low water, and one wider and slower flowing over a boulder area. This is the main sampling area for the low water. These then converge to form a fast flowing fall at low water. The lake never empties, meaning the rapids are constantly supplied with fully marine water at all states of the tide. The narrow channel from the lake and above the rapids has steep shingle sides which have narrow, but very well defined fucoid zonation. The water from the rapids flows over sand and mud flats chich become a channel at low water.
