A global effort by seabird researchers, including those from NIWA, has resulted in the first assessment of where the world’s most threatened seabirds spend their time.
Sadie Mills has come a long way from scaring the inhabitants of Scottish rock pools. Sarah Fraser explains.
A large, orange Scandinavian robot gives NIWA’s marine geologists an in-depth look at changes to the seafloor off Kaikōura.
New Zealanders and Pacific Island communities are on their way to having the most advanced tsunami monitoring system in the world.

Our work

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.
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.

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.

Instrument Systems offers a number of services, including: design, development, manufacture, supply, installation, service and support, calibration, evaluation, hire, training and service contracts.

A cost-effective water level recorder. Comprises a water surface float-driven shaft encoder and internal data logger with rainfall input. Connects directly to compatible communications devices.

When deployed underwater, this self-contained instrument records and analyses water waves. It can trigger other instruments and send alarms via a communications link.

NIWA’s 28-metre research vessel Kaharoa will spend Christmas at sea. Kaharoa will be in the midst of the Indian Ocean, on an epic journey deploying over 100 ocean-profiling ‘Argo’ floats.

Australian Antarctic Division seal biologists were the first to photograph several large icebergs off the coasts of Macquarie Island. Since the beginning of November these icebergs have been pushed north by winds and ocean currents to be within 250 km of New Zealand.

Icebergs approach New Zealand’s sub-Antarctic islands every few years.

NZ scientists endured the dark polar winter to find what drives the dramatic growth of sea ice

Ocean acidification is the name given to the lowering of pH of the oceans as a result of increasing carbon dioxide (CO2) in the atmosphere.
Different groups of organisms need trained specialists (taxonomists) to distinguish a new species from one that is already named and scientifically described

Multibeam echo sounders emit a fan of sound beams to the seafloor to scan a wide swath of the seabed in great detail. 

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.
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.
Understanding the complexity of tidal resources in New Zealand’s coastal waters and examining how extracting tidal energy would influence and be influenced by this variability.
Satellite images can be used to measure phytoplankton biomass in the ocean around New Zealand in order to understand ocean ecosystems, fish populations and greenhouse gas absorbtion.
A survey of valuable ore deposits and ecosystems along the volcanic Kermadec Ridge north of New Zealand, designed to inform both potential development and management of seabed resources in the area.
This research aims to provide better predictions of changes in the ocean and climate system, particularly the way in which the ocean around New Zealand regulates greenhouse gases and clouds.
This project uses the analysis of ocean floor sediments to help discover a 20,000 year history of major earthquakes in the Alpine Fault and Hikurangi region.
How can we help you?

NIWA combines systematics and taxonomic expertise and resources to help meet the requirements of the New Zealand Biodiversity Strategy and related international initiatives. Our biosecurity work ranges from identifying invasive marine species to managing aquatic weeds.

Underwater canyon mapping reveals more seafloor secrets

This diagram shows cross-section views of the Moeraki/Haast channel system.

NIWA scientists have completed another successful voyage to the west coast of the South Island to study the enormous underwater canyon system in the area.
During the 15-day voyage, RV Tangaroa crossed the canyons region collecting mulitbeam bathymetry to map two tributary systems of the Cook/Hokitika canyon system and an additional 400 kilometres of the Moeraki/Haast canyon system.
