Atmospheric analysis

Data from our research which we make publicly available.

Some simple steps to minimise the effects of mining activities on water quality and mahinga kai.

Sometimes wind can feel like a bit of a mystery because we can feel it, but not see it.

River floods occur when water spills from a river channel onto land that is normally dry, and are one of New Zealand's costliest natural hazards.

Tuna or freshwater eels are a very significant, widely-valued, heavily-exploited, culturally iconic mahinga kai resource.

A regional climatology is a summary of the typical weather and climate of a region, based on historical data observations made at climate stations located within the region.

Tuna are found in all sorts of habitats (places), including coastal estuaries, lakes, wetlands, rivers, mountain streams and even alpine tarns.

El Niño accounts for less than 25 percent of the year-to year variance in seasonal rainfall and temperature at most locations in New Zealand, however its effects can be significant.

These datasets are available in a range of formats.
