Ocean modelling

Casal2 is an advanced software package developed by NIWA for modelling the population dynamics of marine species.

New Zealand’s coast is sculpted by ocean waves. Some wave conditions bring joy to surfers and beachgoers, but, at other times, waves can cause major hazards at sea or along the shore.

NIWA answers a wide range of scientific questions using ocean modelling. These models can be linked to well established weather forecasting models to predict ocean temperature, sea level and the dispersal of pollution.

Understanding how material released into the ocean spreads is very important in the case of oil spills, sediment transport and the release of invasive species. 

This research project focusses on modelling atmospheric chemistry and climate from the surface to the top of the stratosphere, using sophisticated chemistry-climate models.

NIWA has developed an Urban Stormwater Contaminant (USC) model to enable urban planners to predict sedimentation and heavy metal accumulation in estuaries and identify problem areas in order to target mitigation measures.

This project was undertaken for Auckland Regional Council to identify significant sources of contaminants in the central Waitemata and southeastern Manukau Harbours.
