Atmospheric analysis

The ability to properly manage our freshwater resources requires a solid understanding of the flora and fauna which live in and interact with them.

Radio and acoustic tracking of fish (or any animal) allows the movement and activity of animals to be recorded over the life of the transmitter (battery size dependent).

Passive Integrated Transponders (PIT) are used to tag fish (or any animal) for life.

Scientists set sail on NIWA's research vessel Kaharoa this week to film and explore many aspects of life in deep-sea habitats, and capture fish that are new to science, in the Kermadec Trench, northeast of New Zealand.

Our freshwater fauna are wonderfully diverse and, according to NIWA Freshwater Ecologist Dr Richard Storey, there's nothing among them that we need to be afraid of.

An experiment in Henderson Creek, Auckland, has demonstrated how tidal creeks variously import, export and deposit sediment, depending on the wind and freshwater runoff, and modulated by the tide.

The mako shark is fast and fascinating. The shortfin mako, Isurus oxyrinchus, has been recorded swimming at speeds of about 100km/h.
