Summary
Water and shellfish monitoring of Whitianga Harbour is undertaken to examine the consequences of the marina development and operation. Pre-marina development baseline data is collected and commented on. Whitianga Marina consent monitoring.
Content
Micro-organism, heavy metals and petroleum hydrocarbon concentrations in water and shellfish samples, along with run number, date and time of sampling, tide details, and comments/observations.

4. Data acquisition information

Collection Date
1993-1994.
Methodology
See Smith (1993) for collection procedures. Total Petroleum Hydrocarbon (TPH) analysis – Dionex application, saponification/methylene chloride extraction and silica treatment. Analysis is by gas chromatography with flame ionisation detection.

5. Data quality information

Known Limitations
Gaps in collection: Not reported Data quality: Water sample preparation and analysis – US EPA protocol Attribute accuracy: Smith (1993) recommends changes to the monitoring methods as sampling sediment for metals and hydrocarbons was impractical. Recommended changes include eliminating sediment sampling and substituting hydrocarbon analysis of the shellfish. Completeness: The TPH analysis for the first four analyses (Runs 93/1-4) involved less rigorous extraction because it did not incorporate the saponification/methylene chloride extraction step.
