Atmospheric analysis

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

  • Te Kūwaha tools and resources

    NIWA is constantly developing new tools and resources for use by specific stakeholders, communities, and schools.
  • Forecasting irrigation potential: a case study in the Waimakariri River catchment

    Research Project
    Farmers rely on irrigation, but water is a limited resource and little is know about how to manage it best. NIWA has developed a hydrology and soil science model to show how much to water, and when, to get the best results.
  • Habitat requirements of New Zealand freshwater fish

    Research Project
    New Zealand's rivers and streams, and the diverse fish that live in them, are worth protecting. But the question of which species prefer to live where was unanswered until NIWA completed this major survey.
  • Restoring Kōaro in the Rotorua lakes

    Research Project
    The kōaro was once abundant in the Te Arawa lakes near Rotorua in New Zealand’s North Island. NIWA has assessed the viability of restoring this species in the region.
  • Deepsea minerals of the Kermadec Ridge - geophysical prospectivity and environmental impacts

    Research Project
    A survey of valuable ore deposits and ecosystems along the volcanic Kermadec Ridge north of New Zealand, designed to inform both potential development and management of seabed resources in the area.
  • NZ SOLAS (Ocean–Atmosphere Interactions)

    Research Project
    This research aims to provide better predictions of changes in the ocean and climate system, particularly the way in which the ocean around New Zealand regulates greenhouse gases and clouds.
  • Greenhouse gases and climate sensitivity - insights from ice cores

    Research Project
    By analysing air trapped in ancient ice we can see how wetlands and permafrosts responded to warming periods in the past, and help predict what will happen in the future.

    Accessibility

    We have designed this site with accessibility in mind. There is a skip to content link on each page, and we try and maintain useful document heading structure and meaningful hyperlinks. That said, there is a wide variety of content which has been loaded over many years, so some pages may work better than others.
