Our work

Ocean acidification conditions around the New Zealand coast are being measured to establish baseline conditions and to quantify future change.
NIWA is conducting a five–year study to map changes in the distribution of plankton species in surface waters between New Zealand and the Ross Sea.
Our oceans are expected to become more acidic as carbon dioxide concentrations rise. This will likely have impacts on the plankton, which play a major role in ocean ecosystems and processes.
Where and when do white sharks occur in New Zealand waters, and how can fisheries bycatch be reduced?
