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.

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.

This dataset provides the most up-to-date bathymetry of one of the largest areas of deep-water seabed under national jurisdiction.

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.

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.

This project aims to increase our knowledge of aquatic ecosystems and their restoration, and apply this to degraded streams, rivers, lakes and estuaries.

The NIWA Biodiversity Memoirs are comprehensive, definitive, illustrated reference works that capture the rigorous, peer-reviewed scientific study of New Zealand’s distinctive marine fauna and flora.
