New NIWA-led research shows increasing flood risk is going to be what leads people to make changes to adapt to sea-level rise.
With cascading waterfalls and native bush tumbling down mountainous terrain, Fiordland is one of the most eye-catching parts of the country. But peer beneath the waves and you'll see that Fiordland's marine invertebrate and seaweed communities are every bit as remarkable and awe-inspiring.
A project is under way to determine whether Aotearoa New Zealand’s long defunct rock oyster industry can be revived.
A pilot study carried out by NIWA and the University of Auckland has found microplastics in samples collected from the seafloor in the Marlborough Sounds.

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.

Antarctic science onboard NIWA’s RV Tangaroa
Researchers are working their way through a wealth of new Antarctic marine data after RV Tangaroa successfully completed its five week scientific voyage to the Ross Sea.

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

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.

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.

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.

 

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."

A team of international scientists, led by NIWA Oceanographer Dr Philip Boyd, departs from Auckland on 6 June and sails towards the waters South of New Caledonia this week. They are onboard Research Vessel Tangaroa, for the second leg of the GEOTRACES programme: a ten-year international study of trace elements in the marine environment.

Ground-breaking research by NIWA and The University of Auckland, investigating the annual movements of New Zealand seabirds migrating within the Pacific Ocean, has revealed that populations are genetically distinct, and have been for centuries as a result of their differing migration behavior.

This measures and records the Electrical Conductivity (EC) and temperature of water.

This analog output sensor provides accurate long-term measurements of water depth and temperature in bores, drains and rivers.

The 6542B can measure water depths of up to 20 m and comes in five standard ranges: 1, 2, 5, 10 or 20 metres of water.

It has an accuracy of better than +/-1% of full scale and water level and temperature outputs are available as two separate analogue voltage outputs for connection to a data logger.

This ultrasonic Doppler instrument is a compact, easy to use system for measuring water flow in rivers, channels and pipes.

Uses a float and counterweight system to convert water level into an electronic output that can be read by a datalogger. Accurate to within a millimetre over a wide range.

This has 16 analog inputs with an accuracy of better than 0.1% of full scale. You can configure inputs as single ended or differential and select from four input signal ranges.

The Neon Applications software is a suite of software and documentation which allows clients to set up their own Neon system on existing server hardware, or new server hardware located at the client’s premises.

The NRT is a small self-contained unit which connects to sensors, records readings from them and transmits the data to a central server via satellite communications.

The NRT is a small self-contained unit which connects to sensors, records readings from them and transmits the data to a central server via a cellular telephone network.
