Turnly's Port, NE Coast.
Survey number: 555 Event number: 19850420/21 Date: 1985-04-20 GPS: 55.02483,-5.97000. Depth: 3.5 to 0.2 m. [ View map ]
Site Description: The site is a medium igneous boulder shore, with a freshwater inflow to the south, where a stream flows across the boulders. There is a small sandstone outcrop to the south holding a wide shallow mid shore rockpool. In addition, there is a small number of clay outcrops scattered over the shore, and the lower shore contains angular limestone boulders scattered among the basalt. The immediate transect area is fucoid dominated, with an extensive area of Ulva (originally recorded as Enteromorpha), and other green algae where the freshwater meets the upper shore. A large area of Fucus ceranoides surrounds the Ulva (originally recorded as Enteromorpha). However to the north and south of the transect site, the intertidal is dominated by littorinids on the mid-upper shore and by barnacles, limpets and Nucella on the mid to lower shore. The local abundance of fucoids may thus be a result of the proximity of the freshwater inflow. The upper part of the Laminaria zone was exposed at low tide, but even so, the intertidal did not seem particularly rich.
