New findings from the record-breaking Tongan volcanic eruption are “surprising and unexpected”, say scientists from New Zealand’s National Institute for Water and Atmospheric Research (NIWA).
NIWA is contributing to an international effort to help developing countries reduce the impact of biofouling on aquatic-based industries and environments.
NIWA and The Nippon Foundation are undertaking a mission to discover the undersea impacts of the recent Tongan volcanic eruption.
New research from the Deep South Challenge: Changing with our Climate and NIWA shows that New Zealand could experience very long and “very severe” marine heatwaves by the end of the century.

Our work

Clouds over the ocean, and how they trap or emit radiation from the sun, are partly influenced by the biology, biogeochemistry and physics of the surface ocean below.

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. 

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

Dive into the alien world of plankton in the Ross Sea

Plankton are the base of the oceans food web and are vital to our survival. But as our world changes will they be able to continue to play this essential role? Join us as we follow a group of NIWA scientists investigating various aspects of this question in the ocean around Antarctica.

Ocean Acidification
This video has been produced to highlight ocean acidification as a potential issue affecting the NZ shellfish aquaculture industry

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.

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.

Dr Philip Boyd on geoengineering

NIWA's Dr Philip Boyd on geoengineering and the research which won him and a team of scientists from NIWA and Otago University the 2011 Prime Minister's Science Prize.

A team of scientists from NIWA and the University of Otago has won the top 2011 Prime Minister's Science Prize for their research into guiding the world's response to climate change.

A historic agreement, aimed at improving country-to-country collaboration on marine research, observations and data management between New Zealand and Australia, has been signed in Canberra this morning.

Voyage updates from voyage leader Scott Nodder.

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

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. 

NIWA scientists have worked for many years on Antarctic atmospheric processes and aquatic ecosystems.

Geosciences 2011

28 November 2011 to 3 December 2011

 

NIWA is sponsoring Geosciences 2011, the Geoscience Society of New Zealand's annual conference.

This year's conference is being held in Nelson and will cover a broad range of geological and geophysical research being undertaken in New Zealand.

For further information see the conference website

In a world first, NIWA has designed a regional climate change ocean 'atlas' - for our Exclusive Economic Zone (EEZ).

Craig Stevens on Antarctic Sea Ice

Principal Scientist Craig Stevens talks about what NIWA's sonar equipment can tell us about ocean turbulence, and what's in store for sea ice around Antarctica and the Arctic. 

Antarctic Whale Expedition 2010

After a successful six weeks in the Southern Ocean, the Australian led Antarctic whale expedition is due to arrive in Wellington, New Zealand, on 15 March 2010. 

Great white sharks - sighted, tagged and tracked

Scientists from DOC, NIWA, and the University of Auckland are building a unique picture of New Zealand's great white shark population.

Kaikoura Canyon Seabed Life

The video represents a number of clips that have been spliced together to illustrate the abundant life associated with the muddy seabed sediments in Kaikoura Canyon at 1000m.

The Antarctic atmosphere is physically and chemically unique and influences all latitudes. The goal of this programme is to improve our understanding of the Antarctic atmosphere's role in global change and its response to that change.

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.

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

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

The science team includes plant and animal ecologists with expertise in a range of fields.

Scientists completed a successful three-week field tagging trip in April 2011, where they tagged a record 27 great white sharks around the Titi (Muttonbird) Islands off the northeast coast of Stewart Island.
