Sedimentation effects

A combination of field surveys and on-site observations are being used along with laboratory-based experiments to determine the effects of seabed disturbance on benthic life.

AWATEA 10th Annual Conference

19 May 2016

The Aotearoa Wave and Tidal Energy Association (AWATEA) is hosting it's 10th annual conference on marine energy.

What does NIWA do? The answer might surprise you. This video is an introduction to NIWA scientists and the wide range of work they do. Our staff work across freshwater,climate and ocean research platforms throughout New Zealand and the wider Pacific region.

Pig power

Right now, millions of cubic metres of biogas either gets flared off, or wafts downwind to annoy the neighbours. But that gas could be generating electricity, powering vehicles and balancing our trade deficit at the same time, finds Dave Hansford.

Pig power science yields good results in NZ and overseas

27 February 2012

An innovative biogas system, developed at NIWA Hamilton, has been embraced by the Australian pork industry. It provides an alternative electricity and heating source.

Biogas from pig farms

NIWA, in collaboration with industry partners, has demonstrated that Covered Anaerobic Pond (CAP) systems for the collection and use of biogas from piggery waste can make good financial sense, and improve the environmental impact of livestock farming substantially.

The winds of change

Much of our electricity now comes from rain and wind, but, asks Greta Shirley, can they keep the lights on in a changing climate?

Craig Stevens on Cook Strait tidal energy

Dr Craig Stevens from NIWA discusses the potential for turbines to extract tidal energy from New Zealand's Cook Strait.

Current conversion - tidal and wave energy in New Zealand

Technology for extracting energy from wave and tidal currents is now a viable alternative to traditional power generation methods.

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.
