Plankton biodiversity in the Southern Ocean

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.

Effects of ocean acidification on plankton in New Zealand waters

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.

White sharks

Where and when do white sharks occur in New Zealand waters, and how can fisheries bycatch be reduced?

“New Zealand urgently needs a National Oceans Strategy” – NIWA Chairman

6 July 2011

NIWA Chairman Chris Mace says New Zealand urgently needs a National Oceans Strategy, to sustainably manage and use its extensive marine resources to boost the economy.

"There is huge untapped potential in our oceans and coastal waters, and the Government has clearly indicated their intention to increase the use of these resources. Under the current global economic environment, I think that is prudent. But without an integrated oceans strategy, our ability to sustainably manage those resources will clearly be compromised."
