Estuarine Environmental Assessment and Monitoring, A National Protocol. Part A. Development, Part B. Appendices and Part C. Application. Prepared for supporting Councils and the Ministry for the Environment, Sustainable Management Fund Contract No.5096. Part A. 93p. Part B. 159p. Part C 40p plus field sheets. 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).
