Oceanography and Marine Water Quality in the Nelson Bays

Information is available on oceanography, coastal water quality and the origin and processing of nutrients in the Nelson Bays, as well as the Golden Bay Marine Monitoring Buoy.

Oceanography in Tasman and Golden Bay     

From summer 2001 to spring 2002, National Institute and Water and Atmospheric Research Ltd (NIWA) made four oceanographic voyages through Tasman and Golden Bays, on the research vessel Kaharoa. A major objective of the research was to understand the ecology of the phytoplankton that lives in these waters.

Coastal Water Quality

Tasman and Golden Bay face North East and have a wide opening to Cook Strait. The water quality is influenced by oceanic water more so than the rivers that drain to the coast. However, when the rivers are in flood they can impact the water quality around the offshore marine farms and the harvesting of shellfish is stopped.

The waters close to the coast are influenced by runoff from the land to a greater degree.  Tasman District Council measures the water quality for swimming during the summer period

Origin and Processing of Nutrients in Golden and Tasman Bay 

Origin and processing of nutrients in Golden and Tasman Bay is a report funded by Envirolink (Foundation for Research Science and Technology) and produced for Tasman by the National Institute and Water and Atmospheric Research Ltd. The report looks at the sources of nutrients and their fate in Tasman and Golden Bay.

Golden Bay Meteorological Buoy Data

The meteorological buoy located in the centre of Golden Bay is a joint project funded by the National Institute and Water and Atmospheric Research Ltd, Tasman District Council and Envirolink (Foundation for Research Science and Technology). The buoy collects data from various meteorological sensors on an hourly basis and feeds the data to the Councils office in Richmond.
