Atmospheric analysis

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.

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

We offer a range of ecological monitoring tools.

This dataset provides the most up-to-date bathymetry of one of the largest areas of deep-water seabed under national jurisdiction. The 250m resolution gridded bathymetric data set encompasses New Zealand's Exclusive Economic Zone and is available in multiple high-resolution file formats to suit a range of imagery and mapping needs.

NIWA provides online access to major climate and environmental monitoring systems, databases and forecasting tools.

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.
