Atmospheric analysis

New Zealand’s forests and other land areas may be absorbing up to 60% more carbon dioxide than has been calculated, with much of this uptake likely occurring in native forests, NIWA scientists have discovered.

Once in freshwater, glass eels develop into darker pigmented juvenile eels known as elvers.

The UV Index is a measure of the intensity of UV radiation. The larger the number, the more intense the UV. In New Zealand, its maximum summer value is generally about 12, but it can exceed 13 in the far North. In winter it reaches peak values of 1 or 2. Values of 10 or more should be considered as "extreme". At high altitude tropical sites (eg Mauna Loa Observatory, Hawaii), the UV Index can exceed 20.The UV Index supersedes the idea of "Time to Burn" or "Burn Time", which has been used previously in New Zealand.

A carbon neutral activity is one that has a carbon footprint of zero.
