Atmospheric analysis

NIWA's long-running 'seven-station' series shows NZ's average annual temperature has increased by about 1 °C over the past 100 years.

Using its broad base of capability, NIWA is creating a new aquaculture species for New Zealand - hāpuku - for sale in the world's fine dining sector.

The Baring Head station, which overlooks Cook Strait, has been operating since 1972 and the data collected there makes significant contributions to our global understanding of greenhouse gases.

Find information about New Zealand's temperature record and climate change in our information and resources section.

Regional-scale climate projections assist local authorities to assess risks presented by climate change now and prepare their communities for the future impacts.

Using a novel observational platform – ocean gliders—this research will observe and understand subsurface variations in temperature, salinity, oxygen and biological factors in water shallower than 200 metres – what we consider to be the shelf seas.

The main purpose of Ngā Waihotanga Iho is to provide tools for the public to measure environmental changes that occur in estuaries over time. These changes may occur due to natural processes and/or human activities.

Black carbon, commonly known as soot, is made of microscopic particles generated by incomplete combustion. Download our latest maps of long-term average concentrations of black carbon from road traffic. Equivalent maps for nitrogen dioxide (NO2) are coming soon.

Nutrition underpins the performance of fish stocks in terms of health, growth (production) and reproduction.

NIWA participates in the Total Carbon Column Observing Network, a ground-based observing network dedicated to making precise and accurate measurements of greenhouse gas concentrations in different parts of the atmosphere.

One of NIWA's core areas of research and consultancy services are the broodstock development of aquaculture species and breeding strategy.
