Intertidal soft sediment monitoring (Canterbury Region)

Physical and biological monitoring of estuaries within the Canterbury region for Environment Canterbury. Sampling sites are located in Brooklands Lagoon, Ashley/Saltwater Creek Estuary, Okains Bay estuary, Akaroa Harbour and Lyttelton Harbour.

Sampling frequency = annual (Mar/Apr) for infaunal cores and sediment, 2-6yearly (Aug-Oct) for other sediment quality samples.

Sampling began in 2009 (2010 for sediments) and is ongoing.

Number of sites = 18 (benthic sampling at 8).

Extent of site = ecological sites: 1200m2 (60m x 20m), sediment sites: 1000m2 (50m x 20m).

Number of replicates = 12 infaunal core samples, 5 replicate sediment samples (composite of 10 subsamples) per site.

Measured variables = infaunal communities (species identifed to lowest taxonomic level possible and enumerated), sediment characteristics (annual): grain size, reodx (in field) chlorophyll-a, organic matter, total organic carbon, total nitrogen and total recoverable phosphorus. 6yearly sediment analyses measure grain size, redox (in field), ash-free dry weight, cadmium, nickel, lead, zinc, cromium, copper, arsenic and organics.

Sampling protocol & QA = Benthic and sediment sampling use similar methods to those outlined in the Estuary Monitoring Protocol by Robertson et al. (2002).

All animals are identified internally, external taxonomic experts used for individuals not able to be identified.

Sediment quality: Follows the methodology developed by ARC.The top 2 cm of sediment is sampled, and processing is outsourced (Malvern Particle Analyser).

Quality and validity

Lineage

Quality assurance was imposed on methods.

Temporal data were in NZST.

Data collection information: Infaunal core = 150mm tall x 130mm diameter, intertidal quadrat = 0.5m x 0.5m, sediment sample = top 20mm surface sediment collected.

Origin from which minimum and maximum values are measured: chart datum

NOTE: The data are not yet available on the Environment Canterbury website.
