Marine Ecology - Rocky Reefs (Auckland Region)

Physical and biological monitoring of rocky reefs within the Auckland region for Auckland Regional Council. Sampling sites are located in Waitemata Harbour (Meola Reef), East Coast Bays, Leigh, Tawharanui and Mokohinau Islands.

Sampling frequency = annual for ecology (Meola intertidal in Oct, all subtidal reefs in Feb/Mar) and 6weekly for sediment.

Sampling began in 1998 (not at all sites) and is ongoing, except for Leigh and Mokohinau Islands which have not been sampled since 2010.

Number of sites = Meola subtidal (6), intertidal (5), Little Manly, Long Bay, Torbay, Campbells Bay (5 each), Leigh, Tawharanui, Mokohinau Islands (1 each). Note intertidal ecological data was also collected at Long Bay, Torbay, Mairangi Bay and Browns Bay until 2006.

Number of replicates = Varies depending on location; Meola, Little Manly, Long Bay, Torbay and Campbells Bay subtidal (7 quadrats + 1 sediment trap per site), Meola intertidal (10 permanent quadrat locations per site). Leigh, Tawharanui, Mokohinau Islands (5 quadrats at 2-4 depth strata (0-3, 4-6, 7-9, 10-15m).

Measured variables = Macrofaunal communities (visual observer counts and measures using 1m2 quadrat).

Sediment characteristics. Sampling protocol & QA = Internal sampling protocol, University of Auckland laboratories. Uniservices internal QA procedures.
