Atmospheric analysis

NIWA climate scientists present the NIWA 2016 Annual Climate Summary.

This research project investigated whether the mechanisms for periphyton removal in rivers relate more directly to hydraulic and geomorphic conditions than flow metrics.

An update describing soil moisture across the country to help assess whether severely to extremely dry conditions are occurring or imminent.

A NIWA technician spends four days and three nights on a crowded boat heading to one of the most remote places in the Pacific to help install a weather station. Conditions are so arduous he decides to quit his job - but how do you do that in the middle of the ocean?

Summer is for scientific fieldwork. Three NIWA scientists are heading into the wild blue yonder, some with fancy technology and others with a coffee cup and a bag of party balloons.

Once you have identified the problem, and applied the necessary tools for restoring kōura to your stream, the next phase of your project is to monitor the site to see whether restoration works.

The tools available for restoring kōura to lakes and streams depend on what is causing kōura to decline.

This year is the 2400th anniversary of the birth of Aristotle, a philosopher and scientist (384 BCE), who among other many great achievements was the first person to describe the structure, ecology, and diversity of sea urchins – way back in the 4th century BC.

Habitat and biological factors factors affect why kōura rare or absent in your waterway.

First, determine if kōura should be present in your stream.

This is a special series of stories put out to the media in the 2016/2017 summer.
