Developing probabilistic scenarios of expected future regional climate changes.

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.

Temperature trends from 1930s to present day

Understanding how hazards impact people and the environment provides the foundation for informed decision making for a resilient Pacific.

NIWA collects wave data, develops and verifies wave forecasting systems, and is developing and producing wave projections.

NIWA expends considerable effort on determining the age of commercial fish species. But why age a fish? And how do we do it?

This collaborative NZaid project worked with coastal Fijian villagers at Votua on the Coral Coast of Viti Levu to develop pragmatic water supply and waste treatment solutions to protect public health and reduce contamination of coastal waters.

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

A range of physical and chemical variables are measured in the NRWQN.

Projections of how climate change is likely to affect New Zealand.

Maps of average annual rainfall, temperature and other climate variables have been produced for all of New Zealand, based on the period 1981–2010.

The current method for calculating wind speed-up is inadequate, and can grossly under-predict correct design wind speeds in NZ's complex terrain.
