  • 2021 - Hikurangi margin

    Voyage
    Underwater Remotely Operated Vehicle helping scientists collect the latest earthquake data.
  • Hotspot Watch 12 March 2021

    Hotspot
    A weekly update describing soil moisture patterns across the country to show where dry to extremely dry conditions are occurring or imminent. Regions experiencing significant soil moisture deficits are deemed “hotspots”. Persistent hotspot regions have the potential to develop into drought.
  • Fundamental Climate Observations

    Research Project
    Get data, time series plots and maps for key climate indicators and present day context here.

  • Climate changes, impacts and implications for New Zealand

    Research Project
    The Climate Changes, Impacts & Implications project ran from 2012 to 2016 and aimed to update and improve projections of climate trends, variability and extremes across New Zealand out to 2100.
  • Air Grid: using grid monitoring to map air quality

    Research Project
    Air quality is almost never consistent across NZ’s towns – polluted air can readily be transported on the breeze and accumulate in different locations.
  • Seabirds spend nearly 40% of their time on high seas, study finds

    Media release
