8.2 Approach and Methodology
8.2.1 Study Sites
Spread along the shoreline of Saldanha Bay, eight rocky shore sampling sites were first visited
during the baseline survey in 2005, and annually since 2008. The 2011 survey was conducted over
the period 15-18 April 2011. Figure 8.1 depicts the location of the study sites. The sites Dive
School and Terminal are situated along the northern shore in Small Bay. Marcus Island, Iron Ore
Terminal and Lynch Point are in Big Bay, as are the sites Schaapen Island East and West, located
on Schaapen Island in the entrance to Langebaan Lagoon. The site North Bay is situated in Outer
Bay at the outlet of Saldanha Bay.
