  3. Shellfish (monitor 54 sites for microbial/bacterial contamination every 3 years with a subset of 9 sites also test for metals and organic substances)
  4. Dinoflagellettes (monitor for the presence of dinoflagellete cysts at 5 Tauranga Harbour sites in the Port area.
  5. Offshore open water quality

Management Evaluation

  
Original purpose. To address Environment BOP's responsibilities under RMA to monitor the state of the environment. The parameters measured are considered sufficiently sensitive to use for long term monitoring to identify the effectiveness or otherwise of plan policy and implementation.
Relationships with classification systems. N/A
Relationships with other databases N/A
Database uses? Environment BOP, Ministry of Health, district councils, consultants, public.
Public awareness of the database Results of monitoring programmes reported and publicised and all reports are sent to district and school libraries.
Database strengths. Includes regular measurements for a range of parameters from throughout the coastal part of the region.
Database limitations. -

 

What are the Current and Emerging Uses of the Database for:

  
Assisting with determining historic state/baseline. Yes - For the time records have been collected (1990 to present day)
Assisting with determining current state/baseline. Yes
Assisting with modeling possible future outcomes. Yes - possible
Risk assessment. Yes. Sites potentially at risk of poor water quality can be identified.
Monitoring site selection and sample design. Yes - possible
Aggregating and reporting data locally, regionally or nationally. Possible at local and region level.
