Atmospheric analysis

Rig shark is an important inshore commercial fish species in New Zealand, and we need to understand more about their habitats, movements, nursery grounds and vulnerability to human impacts to ensure they are managed sustainably and their productivity is enhanced.

Greenhouse gases are atmospheric gases that intercept long-wave (mainly infrared) radiation emitted from the Earth's surface.

This calculator estimates the solar energy that can be collected by a solar capture device (solar panel) at a given address, panel direction and roof slope.

Instream barriers and diversions alter the natural flow of rivers, streams, and lakes.

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

We are currently steaming out towards our survey area, the Louisville Seamount Chain, which is about 1500 km from Wellington.

New Zealand has low-lying coastal areas that are vulnerable to inundation (flooding) by the sea.

Estuaries are at the bottom of the freshwater drainage network and, effectively, are a part of it. This means that every time we act to protect and enhance streams and rivers we are also benefiting the estuary at the downstream end.

An unavoidable delay in a research ship’s voyage to Antarctica resulted in some surprising and important findings about the behaviour of emperor penguins.

There are two species of kōura or freshwater crayfish in Aotearoa.
