Methane seep research bubbling along

10 September 2019

A chance discovery off the Gisborne coast five years ago is prompting a NIWA scientist to find out more about the link between a field of methane seeps bubbling out of the sea floor and submarine landslides.

Our changing oceans

Feature story

13 June 2019

The on-going rise of atmospheric carbon dioxide (CO₂) that is fuelling climate change is also driving significant changes in the waters off our coasts.

Seabed mapping in Marlborough uncovers 10 shipwrecks

The most detailed seafloor mapping of a coastal region off New Zealand has been completed in Marlborough.

Scientists mark 10th anniversary of ocean acidification research

Media Release

9 October 2017

A decade of scientific research into how ocean acidification is affecting New Zealand waters has led to far greater understanding of the vulnerability of our marine ecosystems, according to a newly published review.

Our work

Plankton biodiversity in the Southern Ocean

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.

New Zealand Ocean Acidification Observing Network (NZOA-ON)

Ocean acidification conditions around the New Zealand coast are being measured to establish baseline conditions and to quantify future change.

Effects of ocean acidification on plankton in New Zealand waters

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.

White sharks

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

Services

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

Water Level Recorder - NIWA Hydrologger

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.

Wave Gauge - NIWA DOBIE

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

Monitoring the Antarctic environment

For over two decades NIWA has installed automatic monitoring systems in hostile environments, and probably none is more hostile than the Antarctic. In 2009 we were involved in a project with a difference - installing a climate station as part of a project to protect Scott's Hut, Cape Evans.

Valiant crew of NIWA’s Kaharoa set to spend Christmas in wild waters

23 December 2009

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.

Icebergs South of New Zealand

18 November 2009

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

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

What is ocean acidification?

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.

How do we identify new aquatic species?

First we must be able to recognise if a species is new to science. There are several steps to the process.

How do we map the seafloor?

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