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.

After 50 days in Antarctica, NIWA Vessels staff and scientists worked hard over Easter preparing RV Tangaroa for a month-long voyage along the Macquarie Ridge southwest of New Zealand. Scientists from New Zealand and Australia are on-board.

Huge undersea landslide discovered in Cook Strait

Huge undersea landslide discovered in Cook Strait

Scars, indicating large-scale slope failures, are clearly visible at a depth of around 140 m in Cook Strait.

Undersea mapping in Cook Strait has revealed detail of massive rock movements around a huge canyon, Nicholson Canyon, less than 15 km from Wellington Airport.
Using state-of-the-art multibeam equipment, scientists have discovered that the canyon walls are very steep. The over-300 m high walls have clearly visible scars indicating a large-scale slope collapse or landslide.

New Zealand conducted a major biological survey of the Ross Sea, in the Antarctic, as part of the Census of Antarctic Marine Life (CAML) and International Polar Year (IPY).

Worldwide, there is growing recognition of the services nature provides that effectively sustain life and business on our planet. NIWA research is highlighting the vital services provided by estuarine ecosystems and the threats they face.
Estuaries act as filters and recyclers: processing nutrients, contaminants, and sediments that are washed off the land.

Mahia Peninsula, at the northern end of Hawke’s Bay, is renowned for its beautiful beaches and spectacular surf. But sedimentation is a big problem on some parts of the coast. The water is clouded by fine mud, and nearshore marine habitats such as rocky reefs are blanketed in sediment.

Many of New Zealand’s estuaries are becoming muddier, as sediment washes into them from rivers and stormwater drains and accumulates, rather than being dispersed by tides. Mangrove swamps are a feature of some of our muddy estuaries, and the Firth of Thames is a good example of a place where mangroves and mud are steadily accumulating.

‘The problem that resource managers face in trying to protect coastal environments is that damage is like death of a thousand cuts – it is often the result of many different small disturbances, the effects of which accumulate over time.’ So says NIWA scientist Simon Thrush, who is leading a long-term project on ecological disturbance modelling at NIWA.
Most environmental threats come in the form of some sort of disturbance to natural ecosystems.

Voyage Log and Latest Images
Voyage plot for RV Tangaroa.
Time: 2004-04-14 02:00:00
Position: 41 33. 36S 178 24. 00E
As time permitted, scientists on the SAGE voyage posted descriptions of their daily activities and images of the work they were doing. The voyage track shows the position of RV Tangaroa as the experiment progressed.Thursday, 15 April 2004The final dayAs the SAGE voyage comes to an end, it is only fitting that we have the best weather of the month. After all, we did ask for strong wind conditions to assist in giving high gas exchange, and we certainly got it.
