Atmospheric analysis

NIWA has been using advanced scientific instruments to measure atmospheric trace gases and isotopes for over 50 years.

  • Dairy

    Dairy farms produce milk and milk products that supply both the domestic and the overseas export markets.
  • Agriculture

    The most common agricultural activities in Aotearoa are dairy, cropping, sheep, and beef farming.
  • Bio-oil from wastewater algae

    Research Project
    This project will demonstrate the commercial feasibility of producing bio-oil by the conversion of algae biomass that has been grown in wastewater treatment facilities. In particular we aim to maximise algae production in High Rate Algal Ponds (HRAP) by adding carbon dioxide, and demonstrate energy efficient conversion of algal biomass to bio-oil.

  • Estuarine Ecodiagnostics

    Research Project
    Estuaries are highly valuable systems that provide enormous economic and cultural benefits to all kinds of people. However, expanding human populations and urban development around estuaries is increasing contaminant loads, with metals and polycyclic aromatic hydrocarbons (PAHs) accumulating in sediments.

    Why is there water flowing in a river when it isn’t raining?

    In the absence of rain, most of the flow in a river is water that drains slowly from the ground.
  • Ngā Waihotanga Iho - Iwi estuarine monitoring toolkit

    Research Project
    Ngā Waihotanga Iho, the estuarine monitoring toolkit for Iwi, has been developed to provide tangata whenua with tools to measure environmental changes in their estuaries. While Ngā Waihotanga Iho is based on sound science principles, it is also underpinned by tangata whenua values.
  • Mātauranga Māori and sustainable management of New Zealand fisheries

    Research Project
    Using a collaborative case study approach, the aim of this project is to assist tangata whenua to bring together different, yet complementary knowledge systems - distinct Māori knowledge and conventional fisheries and ecosystem information.
