Estuarine Ecology Monitoring Programme (Hawke's Bay Region)

Physical and biological monitoring of estuaries within the Hawke's Bay region for Hawke's Bay Regional Council. Sampling sites are located in the Porangahau and Ahuriri estuaries.

Sampling frequency = annual (Mar).

Sampling began in 2006 and is ongoing.

Number of sites = 5 total.

Extent of site = 1800m2 (60m x 30m).

Number of replicates = 10 infaunal cores and 10 sediment samples per site.

Measured variables = Infaunal communities (species identified to lowest taxonomic level possible and enumerated). Epifaunal quadrat (0.25m2).

Sediment characteristics (Basic grain size only, TOC, ash free dry weight, redox, chlorophyll a, nitrogen, phosphorus, cadmium, nickel, lead, zinc, chromium, copper and arsenic).

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

Internal QA procedures. Sediment analysis by Cawthron Ltd and Hills Laboratory.

Statement

Quality assurance was imposed on methods.

Geographic data used NZTM (LINZ). 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.
