Our work

New Zealand Ocean Acidification Observing Network (NZOA-ON)

Ocean acidification conditions around the New Zealand coast are being measured to establish baseline conditions and to quantify future change.

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?

Echo, Echo: Scanning the Seafloor on R.V. Tangaroa

NIWA ocean geologist Dr Joshu Mountjoy explains how the R.V. Tangaroa's multibeam system is used for bathymetric (seabed) mapping, and some of the benefits which come out of this mapping.

Big Fish, Calm Sea - White Shark Tagging off Stewart Island

Tagging White Sharks off Stewart Island, NZ Scientists from DOC, NIWA, and the University of Auckland are building a unique picture of New Zealand's great white shark population.

In brief: Snapper that stay home, stay safe

Creating marine reserves may affect the behaviour of some fish that live in them, a NIWA study has found.

In brief: Birds of a feather don’t always flock together

They might be the same species, but two discrete populations of Cooks petrels – one from Little Barrier Island in the Hauraki Gulf, and the other more than 2000km away on Whenua Hou, or Codfish Island – keep their distance genetically.

NIWA's research vessel Tangaroa was at sea 2-20 November 2011 for the TAN1116 voyage.

Marine food webs

We need information on the food web structures of our marine ecosystems in order to manage the effects on the ecosystem of fishing, aquaculture and mining, as well as understanding the potential impacts of climate variability and change on our oceans.

Antarctic aquatic ecosystems: summary

Polar ecosystems face physical constraints that set them apart from their warmer counterparts. The greatest constraint is the impact of prolonged periods of winter darkness and sub-zero temperatures.

Antarctic marine ecosystems

All aquatic ecosystems are strongly driven by physical processes, and nowhere is this more true than in Antarctica.

“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."
