Atmospheric analysis

Where and when do white sharks occur in New Zealand waters, and how can fisheries bycatch be reduced?

An overview of Science at NIWA

West Coast is New Zealand’s wettest region, and this may be attributed to its exposure to the predominant westerly airflow over the country, combined with the orographic effect of the Southern Alps.

To prepare for changes in climate, our freshwater and oceans decision-makers need information on species vulnerability to climate change.

Compound specific stable isotope analysis techniques are an increasingly useful tool to address many ecological and environmental research questions.

NIWA's educational resources and scientific data are tools for young people to learn about science.

Glass eels (about 5.5 to 7.0 cm) arrive in fresh water during spring, especially during September and October, although they may be present from July to December.

Dry stock farms can cover large areas of hill-country grassland that may be steep and prone to erosion.

This project demonstrates how to assess high value alternative land-use options by means of a quantitative analysis of the growing potential of selected niche crops and tree species.

We have prepared a breakdown of the different guidelines that are available for sampling freshwater fisheries. The overview provides links to key documents that explain what should be considered when designing fish monitoring studies and how to implement the various sampling techniques.
