摘要

This report describes the effects of the disposal of dredged Black Rock Harbor (BRH) sediments on the ambient (predisposal) community and the mode and pattern of recolonization at the Field Verification Program (FVP) site. The recolonization process was measured by documenting the rate of recruitment of the FVP site by the dominant species and comparing this with the ambient (reference) community. The parameters used to describe recolonization anc convergence with the ambient system are species numbers, abundances of numerically dominant species, degree of infaunalization (successional stage), and depth of biogenic mixing of the bottom sediments (another measure of infaunalization). Both quantitative grab samples and the REMOTS interface camera were used to assess recolonization.
