In the present study we measured the salinity at four tidal
creeks and channels and at the beach along a transect running from the upper and lower estuary to the northern shore of the
peninsula (Fig. 1). Subsurface water samples were taken
weekly between January and June from 2001 to 2005 (beach:
2002e2005). The salinity of the samples was measured with
a WTW-LF 197 using the Practical Salinity Scale.
