Healthy Estuary and Rivers of the City (Canterbury Region)
Physical, chemical and biological monitoring of Avon-Heathcote Estuary/Ihuta for Christchurch City Council, Environment Canterbury and the Ihutai Trust programme.
Sampling frequency = annual infaunal, grain size and redox sampling (Mar/Apr), 5 yearly sediment quality sampling, monthly water quality sampling.
Number of sites = 6 (benthic sampling) and 10 (water quality).
Extent of site = 1600m2 (40m x 40m) sites in the estuary, 300m2 (15m x 20m) site in lower Heathcote River and 600m2 (10m x 60m) in lower Avon River.
Number of replicates = 15 infaunal cores per site, 5 replicate sediment samples (composite) from 3 subplots per site, 1 water quality replicate per site.
Measured variables = Infaunal communities (species identifed to lowest taxonomic level possible and enumerated; mudflat snails, crabs, cockles and wedge shells measured.
Percentage cover of epiflora (macroalgae, zostera and benthic microalgae films).
Sediment characteristics (grain size, ash free dry weight, redox, chlorophyll a, nitrogen, phosphorus, cadmium, nickel, lead, zinc, chromium, copper and arsenic).
Water quality samples taken from top 0.5m of water column (salinity, DO%, DO mg/l, temperature, PH, E-coli, Enterococci, faecal coliforms, TP, DRP, TN, NNN, NH4, chloropyll a, turbidity, suspended solids, metals, organic carbon).
Sampling protocol & QA = Benthic and sediment sampling use similar methods to those outlined by Robertson et al. (2002).
Water quality samples follow an internal protocol manual. Analysis by EOS Ecology and external (Malvern Particle Analyser).
