Latest news

NIWA researchers are heading out from Tasman early next week to survey an area thought to be home to important juvenile fish nurseries.
After a decade-long effort, NIWA’s latest Biodiversity Memoir has just rolled off the presses. Written by marine biologist Kareen Schnabel, the 350-page treatise presents everything we currently know about the different kinds of squat lobster living in New Zealand’s waters.
At the bottom of the Southern Ocean, near Cape Adare in East Antarctica, lies an undersea ridge which until this month was only known by its co-ordinates: -71.2132 latitude, 172.1649 longitude.
New ways to address environmental sustainability challenges.

Our work

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.
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.
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.

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.

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.

Where and when do white sharks occur in New Zealand waters, and how can fisheries bycatch be reduced?

NIWA Oceanographer Dr Craig Stevens has returned, with stunning images and data, from a successful month-long research trip in Antarctica, where he led a team of international and New Zealand scientists.

New Zealand's Kaikoura Canyon is a 'biodiversity hotspot', containing far more life than seen before at such depths.
A low-cost weather station for gathering accurate weather data. Wind speed and direction, air temperature, relative humidity, barometric pressure and rainfall data can be accessed from a server, via the internet.

This measures rain by the drop as well as by the tradional 'tip'. We can configure it either with an SDI12 serial data interface or an integral logger with cellular communications.

NIWA’s research vessel Kaharoa set sail from Wellington today, destined for Lyttelton and equipped with seismic survey gear to survey an area of southern Pegasus Bay.

Preliminary results from the first comprehensive survey of the Cook Strait Canyon seabed have begun to reveal tantalising scientific secrets about New Zealand's largest underwater canyon.

Targeted geological sampling and imaging by NIWA scientists next week will help understand active seabed processes in one of New Zealand's largest seafloor features.

On New Year's Day, NIWA's research vessel Tangaroa departs for its first voyage, since its recent $20 million dollar upgrade, making its twentieth consecutive trip to the Chatham Rise to study the abundance of important fish species.
