Diving deep to check up on our lakes

NIWA scientists jump overboard to check out the health the Rotorua Te Arawa lakes. The work is part of NIWA's national LakeSPI programme—an ecological health check for lakes throughout New Zealand. 
Underwater research to protect and maintain New Zealand's freshwater resources.

When deployed underwater, this self-contained instrument records and analyses water waves. It can trigger other instruments and send alarms via a communications link.

Modelling future water quality in Lake Benmore

The lakes of the Upper Waitaki Basin – Lakes Benmore, Aviemore, and Waitaki – are highly valued for their clean water. But land use is intensifying in the lakes’ catchments, and concerns for future water quality are growing. NIWA scientists have worked alongside Waikato University scientists to model  the potential impact of intensifying land use on water quality in Lake Benmore, to help Environment Canterbury with its regional planning.

World first in bio-crude oil research

“The reality is that no one in the world has done anything on this scale. Our trial aims to show that this complete process can be cost-effective and efficient”, says NIWA scientist Dr Rupert Craggs. Twelve years of research by NIWA’s Aquatic Pollution Group has culminated in the world’s first large-scale trial of the production of algal bio-crude oil from wastewater.
