The CB3 coastal belt extends approximately 2880 m and includes thin red lines that separate the individual domain segments. This coastal belt is divided into five BCCS (Biophysical Cross-shore Classification System) domains, the largest of which (Black Rock) is characterized by the cross-shore catenary sequence: 2Cr_fr,paF_saR_igM_fo,sr. The adjacent coastal belt (CB4) is delineated by a thicker red line. All codifications for CB3 can be keyed using Table 1 and the summary data for this coastal belt corresponds directly with Table 3.
