Our work

Climate Present and Past

Climate Present and Past is a core-funded project under NIWA's National Climate Centre. It aims to explore historical climate data and track past changes in climate through a range of approaches.

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.

Ocean acidification and warming

Acidification of the world’s oceans from rising atmospheric carbon dioxide levels reduces the availability of carbonate required by some marine organisms to build shells and skeletons, and potentially affects their ability to maintain existing structures.

Antarctic fisheries research

NIWA’s Antarctic fisheries research is allowing us to investigate possible effects of the longline Antarctic toothfish fishery on the toothfish population and on the local ecosystem.
