Coastal flooding likely to be main driver for adaptation

12 October 2021

New NIWA-led research shows increasing flood risk is going to be what leads people to make changes to adapt to sea-level rise.

Fabulous Fiordland showcased in new e-Guide

Media Release

5 October 2021

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 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

Marine food webs

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.

Changes in juvenile fish habitats

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.

Coastal adaptation to climate change

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

Plastic pollution processes in rivers

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.

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.

Antarctic Coastal Marine Life in a Changing Climate

NIWA marine ecologist Dr Vonda Cummings discusses the likely effects of climate change on marine invertebrates living on the seafloor of the Ross Sea coast.

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.

Electrical Conductivity Logger - Unidata 6536D

This measures and records the Electrical Conductivity (EC) and temperature of water.

Water Depth and Temperature Sensor - Unidata 6542B

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.
