Our work

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.

NIWA’s Tangaroa sets sail to study how Antarctica affects ocean currents

A team of 22 Australian, New Zealand and French scientists will depart Wellington next week, onboard NIWA's RV Tangaroa, for a 42-day voyage to the Mertz Polynya region of Antarctica.

Ocean modelling

NIWA answers a wide range of scientific questions using ocean modelling. These models can be linked to well established weather forecasting models to predict ocean temperature, sea level and the dispersal of pollution.

CTD (Conductivity, Temperature and Depth)

Ocean water properties such as temperature are measured directly, while conductivity is used to tell us the salinity. It also captures water samples at different depths for a variety of chemical and biological measurements made either on the vessel or back in the laboratory.
