Lyttelton Dredge Spoil Monitoring
Lyttelton Port Company’s (LPC) maintenance dredging.
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). Except for in 1992, sediments were also analysed for contaminants (SVOCs, organotins, aliphatic hydrocarbons, trace metals) along with fauna (organotins, SVOCs, trace metals).
Species/community data: Benthic invertebrates, intertidal epibiota & algae
Other data collection: Unknown
Ongoing as part of their consent
Quality assurance: Yes
