Temporal coverage: from 1992 (ongoing) Number of sites: 12 sites (disposal zones, outer harbour control zones, upper harbour regions) Sampling frequency: 1992 baseline survey, a repeat of the survey following granting of permit (1994) and 5 yearly surveys thereafter Main marine environment sampled: Coastal Depth zone: Subtidal/Intertidal Sedimentary type: Soft Community association: Mud Sampling method: Sediment cores, infauna cores, shellfish collection, in-situ water sampling Parameters collected: Sediment physico-chemical properties, infauna community composition, shellfish contamination, water quality Measured variables: Sediment (grain size, organic content), infaunal community composition, intertidal survey (substrate characteristics, zonations patterns of flora/fauna), water quality (salinity, temperature, DO, secchi).
