  • Total suspended particulates concentration in Auckland, 1965–2013

    Ministry for the Environment
    Total suspended particulates (TSP) consist of all solid particles and liquid droplets up to 100 micrometres (μm) in diameter (ie when compared with PM10 and PM2.5, TSP is the equivalent of PM100). TSP can be emitted from the combustion of fuels, such as wood and coal (eg from home heating and industry) and petrol and diesel (from vehicles). Natural...

  • Benzene concentrations 2012–13

    Ministry for the Environment
    Benzene is a volatile organic compound. Motor vehicle use and home heating are the main sources of airborne benzene emissions. Natural sources include volcanoes and forest fires. Benzene can affect the nervous system and is associated with some forms of cancer. Benzene is emitted by human-made (motor vehicles, burning wood or coal for home heating, and...

  • Annual sea surface temperature difference from normal, 1994

    Ministry for the Environment
    The ocean waters surrounding New Zealand vary in temperature from north to south. They interact with heat and moisture in the atmosphere and affect our weather. Long-term changes and short-term variability in sea-surface temperatures can affect marine processes, habitats, and species. Some species may find it hard to survive in changing environmental...

  • Estimated annual Salvin's albatross captures in trawl and longline fisheries...

    Ministry for the Environment
    Along with sea lions, fur seals, and dolphins, seabirds are the protected species most directly affected by fisheries in New Zealand waters. Estimating seabird deaths from bycatch is one way of assessing the pressure some seabird species face from current fishing practices. This dataset relates to the "Bycatch of protected species: seabirds" measure on...

  • Growing season soil moisture deficit, 2011-2012

    Ministry for the Environment
    Soil moisture is important for plant growth. A lack of moisture content over a growing season is a good indicator of drought, which can have social, environmental, and economic impacts. Increasing temperatures and changes in rainfall patterns are expected to increase the frequency and intensity of drought in many regions. Growing season soil moisture...

  • Annual rainfall Units: percentage of normal, 2012

    Ministry for the Environment
    Annual rainfall is the total accumulated rain over one year. Rain is vital for life, including plant growth, drinking water, river ecosystem health, and sanitation. Floods and droughts affect our environment, economy, and recreational opportunities. This layer shows the annual rainfall as a percentage of normal across New Zealand for 2012 as part of the...

  • Bycatch of protected species - Hector’s and Māui’s dolphin entanglements (1921–2008)

    Ministry for the Environment
    The Hector’s and Māui’s dolphins are subspecies of the small dolphin Cephalorhynchus hectori. They are endemic to New Zealand (not found anywhere else). The Hector’s dolphin is classified as nationally endangered, while the Māui’s dolphin is nationally critical. Reporting incidental dolphin deaths from fishing helps us understand the pressures our...

  • Nitrogen dioxide concentration at state highway sites 2007–13

    Ministry for the Environment
    Nitrogen dioxide (NO2) is a gas. It can be emitted directly into the air but is most often formed when nitric oxide (NO) emissions react with other chemicals in the air. Nationally, road motor vehicles are the main human-made source of nitrogen oxides (NOx, the collective term for NO2 and NO). NO2 may cause respiratory infections and reduced lung...

    Ministry for the Environment
    "The rates of establishment (recruitment) of indigenous tree species vary across New Zealand. Changes in the state of the environment (such as from browsing pests, large-scale weather events, or climate change) may change the rates of recruitment of particular tree species. This in turn may alter forest processes. Repeated surveys of the distribution of...
