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.
Coronavirus border restrictions mean six NIWA staff face four straight months at sea in a bid to keep an international ocean research project afloat.
NIWA scientists are heading to the waters around Whakaari/White Island in the Bay of Plenty next week to survey changes to the seafloor.

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.

Seabed Frontier: A Brief History of Bathymetry

NIWA marine geologist John Mitchell gives a brief history of bathymetric (seabed) charting, and how it's been carried out over the last few hundred years. (01:18) 

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.

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.

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.

 

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."
