How green's the bay?
Mean chlorophyll concentrations in the Bay of Plenty for October 1997–2004.
NIWA is applying a cutting-edge method of estimating surface chlorophyll concentrations around the coast to help Environment Bay of Plenty with work on aquaculture management areas.
Chlorophyll is produced by microscopic plants (phytoplankton), and its concentration is related to the amount of phytoplankton in the water. These organisms are at the base of the marine food chain, so it is important to estimate how much phytoplankton there is.
