Harbour Sediment Contaminants Programme (Greater Wellington Region)
Physical, chemical and biological monitoring of subtidal sediments within the Greater Wellington region for Greater Wellington Regional Council.
Sampling sites are located in Wellington and Porirua Harbours.
Sampling frequency = 2-5yearly (Oct/Nov).
Sampling began in 2004 (Porirua) and 2006 (Wellington) and is ongoing.
Number of sites = 22 total: Porirua (5) and Wellington (17, though this will decrease to 10-11).
Extent of site = 20m diameter circular plot.
Depth range sampled: 1.7 m to 23.0 m.
Number of replicates = 8 infaunal cores, 5 sediment samples (composed of 5 sediment cores each) per site.
Measured variables = Infaunal communities (species identified to lowest taxonomic level possible and enumerated).
Sediment characteristics: grain size, TOC cadmium, nickel, lead, zinc, chromium, copper and arsenic.
Sampling protocol & QA = External taxonomic identification of infauna.
Sediment analysis external (Malvern Particle Analyser).

Quality assurance was imposed on methods.
Geographic data used NZTM (LINZ). Temporal data were in NZST.
Data collection information: Infaunal core = 250mm tall x 200mm diameter, sediment core = 120mm x 50mm diameter (surface sediment collected).
Origin from which minimum and maximumvalues measured: mean low water neap tide
