Estuary Monitoring Programme (Northland Region)

Physical and biological monitoring of estuaries within the Northland region for Northland Regional Council. Sampling sites are located in the Whangarei, Ruakaka, Whangaroa, Kaipara and Kerikeri Inlets.

Sampling frequency = annual (Mar), except sediment plates (3monthly). Sampling began in 2006 and is ongoing.

Number of sites = 13 total. Extent of site = 1800m2 (60m x 30m).

Number of replicates = 10 infaunal cores and 5 replicate sediment samples per site.

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

Epifaunal quadrat (0.25m2). Sediment characteristics (grain size, ash free dry weight, redox, nitrogen, phosphorus, cadmium, nickel, lead, zinc, chromium and copper).

Sediment erosion/deposition (cm/y): depth of sediment layer measured (using 2 concrete plates buried at all 13 sites).

Sampling protocol & QA = Benthic and sediment sampling use similar methods to those outlined by Robertson et al. (2002). Internal QA procedures. Larger fauna are indentified internally with small and cryptic animals sent to external taxonomic experts. Sediment analysis external (Malvern Particle Analyser).

Quality and validity

Lineage

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, sediment plates
