New findings from the record-breaking Tongan volcanic eruption are “surprising and unexpected”, say scientists from New Zealand’s National Institute for Water and Atmospheric Research (NIWA).
NIWA is contributing to an international effort to help developing countries reduce the impact of biofouling on aquatic-based industries and environments.
NIWA and The Nippon Foundation are undertaking a mission to discover the undersea impacts of the recent Tongan volcanic eruption.
A robot sea craft is the latest tool NIWA scientists are using to help them count fish.

Our work

Aotearoa New Zealand’s coastal lowlands are our flat low-lying land (or plains) adjacent to coasts and estuaries. Our coastal lowlands are valued for many reasons, including unique ecological wetlands, cultural sites of significance, valued recreational areas, highly-productive agriculture and are popular places to live.

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.

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.

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.

Welcome to the latest edition of Coasts Update. Here we bring you news of some of NIWA's latest research on aspects of coastal ecology, and the possible impacts of climate change on one of our coastal communities.

This measures rain by the drop as well as by the tradional 'tip'. We can configure it either with an SDI12 serial data interface or an integral logger with cellular communications.

Many of New Zealand's rivers fail to meet national guidelines for nutrient levels. NIWA has developed the Catchment Land Use & Environmental Sustainability (CLUES) estuary tool to predict the effects of land use on estuarine nutrient concentrations.

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

NIWA is working on a ministry-funded project to produce a model, validated by 40 years of historic data, to project future wave and storm surges off the coast for two climate change scenarios.

We are investigating the potential effects of the Antarctic toothfish fishery on the species’ predators by trying to understand how significant a prey toothfish are for seals and whales in the Ross Sea.

We are investigating the effects of the Ross Sea toothfish fishery on prey by looking at what the species eat and trying to understand the biology and ecology of these fish.

Here we provide a detailed summary of key outcomes from the Sustainable Aquaculture programme to 30 June 2009.

In this issue we bring you news of recently completed research on: Tauranga Harbour sediments, the Separation Point fishing exclusion zone, the Bay of Islands Coastal Survey, and mapping coastal environmental values.
