Scientist pieces together details of underwater landslides

28 November 2019

New information about landslides that occur on the seafloor off New Zealand’s east coast will help scientists better understand why and where they happen, and the types of threats they pose.

Planning an ocean observation network

Media Release

3 October 2019

New Zealand’s changing ocean environment has prompted the call to develop a system that will keep closer tabs on information from scientific monitoring buoys so the data they produce can be shared as widely as possible.

Methane seep research bubbling along

Media Release

10 September 2019

A chance discovery off the Gisborne coast five years ago is prompting a NIWA scientist to find out more about the link between a field of methane seeps bubbling out of the sea floor and submarine landslides.

Our changing oceans

Feature story

13 June 2019

The on-going rise of atmospheric carbon dioxide (CO₂) that is fuelling climate change is also driving significant changes in the waters off our coasts.

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.

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.

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?

The Iron Hypothesis

NIWA biological oceanographer Dr Philip Boyd explains the iron hypothesis: what it is, its history, and some recent experiments in the Southern Ocean.

Southern Ocean Gas Exchange

The Earth's oceans – particularly the Southern Ocean – play an important role in absorbing carbon dioxide (CO₂) and other trace gases from the atmosphere.

Modelling surface ocean carbon

In order to understand the roles of different processes affecting ocean atmosphere exchange of CO² and DMS it is essential to develop quantitative models for these.

Dynamics of ocean atmosphere exchange

The transfer rate of most gases between the atmosphere and ocean is controlled by processes just beneath the water surface.

Ocean-Atmosphere Interactions

This programme aims to provide better predictions of changes in the ocean and climate system, particularly the way in which the ocean around New Zealand regulates greenhouse gases and clouds.

Our Far South - Rob Murdoch's Blog

Summer Series 2: Weird and wonderful - Tropical visitors (sea snakes, turtles, mahi mahi)

3 January 2012

When you are at the beach this summer, don't be surprised if you're swimming next to a sea snake with a paddle for a tail, a big-headed-turtle, or a magnificently coloured flat-faced fish. New Zealand's got its share of weird and wonderful marine visitors. Several species of sea snake and turtle regularly reach our waters.

Summer Series 1: Hammerhead - the shark with a hammer for a head

27 December 2011

The shark with the hammer-shaped head (Sphyrna zygaena) is a big eater and is potentially dangerous to humans. It has been found in New Zealand coastal waters, in up to 110 metres of water, and on the continental shelf. It is more commonly seen around the North Island.

TAN1116 voyage log - technical updates

Voyage updates from voyage leader Scott Nodder.

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.
