New NIWA-led research shows increasing flood risk is going to be what leads people to make changes to adapt to sea-level rise.
With cascading waterfalls and native bush tumbling down mountainous terrain, Fiordland is one of the most eye-catching parts of the country. But peer beneath the waves and you'll see that Fiordland's marine invertebrate and seaweed communities are every bit as remarkable and awe-inspiring.
A project is under way to determine whether Aotearoa New Zealand’s long defunct rock oyster industry can be revived.
A pilot study carried out by NIWA and the University of Auckland has found microplastics in samples collected from the seafloor in the Marlborough Sounds.

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. 

NIWA is looking for people who have had a long association with the Hauraki Gulf or Marlborough Sounds to help them with a research project on juvenile fish habitats.

NIWA is developing guidelines and advice to help coastal communities adapt to climate change.

Most of the plastic in the ocean originates on land, being carried to the estuaries and coasts by rivers. Managing this plastic on land before it reaches the river could be the key to stemming the tide of marine-bound plastics. The aim of this project is to understand the sources and fate of plastic pollution carried by urban rivers using the Kaiwharawhara Stream as a case study.

Dive into the alien world of plankton in the Ross Sea

Plankton are the base of the oceans food web and are vital to our survival. But as our world changes will they be able to continue to play this essential role? Join us as we follow a group of NIWA scientists investigating various aspects of this question in the ocean around Antarctica.

Next Stop Antarctica

Our Far South is an expedition that aims to raise New Zealanders' awareness of the area south of Stewart Island. Gareth Morgan, Te Radar, scientists and 50 everyday Kiwis are onboard to learn and then share their experience. This is the first video produced by them, showing some of the highlights of the trip so far.

Shallow Survey 2012

30 August 2011 to 31 August 2011

Abstracts submission for the 6th internation Shallow Water survey conference are due on Wednesday 30th August. This conference will explore the latest developments in shallow water surveying.

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.

The 6542B can measure water depths of up to 20 m and comes in five standard ranges: 1, 2, 5, 10 or 20 metres of water.

It has an accuracy of better than +/-1% of full scale and water level and temperature outputs are available as two separate analogue voltage outputs for connection to a data logger.

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.
