Water clarity or turbidity is the cloudiness or haziness in a fluid caused by individual small particles (suspended solids).

Impacts of hydro-electric activities on water quality and mahinga kai.

The atmosphere is comprised of layers based on temperature. These layers are the troposphere, stratosphere, mesosphere and thermosphere.

This daily image of New Zealand from space was created using data from one of NASA's EOS satellites, collected at our receiving station in Lauder, Central Otago.
