Effects of ocean acidification on plankton in New Zealand waters

Date: September 08, 2009
National Centre:

Our oceans are expected to become more acidic as carbon dioxide concentrations rise. This will likely have impacts on the plankton, which play a major role in ocean ecosystems and processes. This study will measure plankton diversity and productivity in New Zealand’s Exclusive Economic Zone (EEZ) and predict their response to ocean acidification, warming, and stratification.

Juvenile giant kokopu

Reintroducing giant kōkopu to Nukumea Stream

Date: December 04, 2009

The giant kōkopu is a native whitebait species considered rare and vulnerable. NIWA is working with Mahurangi Technical Institute and environmental consultancy Boffa Miskell to test the feasibility of reintroducing giant kōkopu to Nukumea Stream, north of Auckland.

Continuous Plankton Recorder

Plankton Biodiversity in the Southern Ocean

Date: August 18, 2009

NIWA is conducting a five–year study to map changes in the distribution of plankton species in surface waters between New Zealand and the Ross Sea. Officially known as Continuous Plankton Recorder Time Series, this study is part of a Ministry of Fisheries marine biodiversity programme.

A Koaro in a Hand

Restoring Kōaro in the Rotorua lakes

Date: March 17, 2009

The kōaro was once abundant in the Te Arawa lakes near Rotorua in New Zealand’s North Island. NIWA has assed the viability of restoring this species in the region.
