Marine biofouling creates a huge headache for New Zealand aquaculture. Read about a promising new technology for controlling biofouling.
From emissions to exposure: are our transport choices making us ill?
Reducing your vehicle’s emissions may not be enough to protect your own health. Ian Longley describes new research that’s getting a fix on personal levels of exposure to air pollution.
Natural purification of groundwater
Graham Fenwick and Mike Scarsbrook explain an ecological service going on beneath our feet.
Ecodiagnostics: biomarkers of shellfish health in urban estuaries
Michael Ahrens describes the search for environmental indicators that can highlight problems for kai moana.
Harnessing the power of sunlight and nanoparticles to combat biofouling
As the world seeks a non-toxic defence against costly biofouling, NIWA and its collaborators are on the track of a new coating for hulls, pilings, and submerged equipment. Craig Depree takes a close look at a nano-solution.
Biogenic habitats and their value to New Zealand fisheries
Mark Morrison, Mireille Consalvey, Katrin Berkenbusch, and Emma Jones explain the economic importance of maintaining diverse and healthy coastal and deepsea habitats.
Improving projections of Antarctic ozone recovery
The Antarctic ozone hole is expected to recover sometime this century, but exactly how and when remains uncertain. Greg Bodeker and the IPY Team are working to improve model projections of the recovery using data from the intensive measurement campaigns of the International Polar Year (IPY).
Linking the world’s oceans: the Antarctic Circumpolar Current
In her year as a New Zealand Science, Mathematics and Technology Teacher Fellow, Jenny Pollock has focused her attention on the ACC.
Using Water & Atmosphere in your classroom
One of NIWA’s aims with this magazine is to contribute to science education in New Zealand. To this end we distribute Water & Atmosphere without charge to New Zealand high schools. Articles are assigned ‘Curriculum Connections’ to indicate which of the NZ NCEA Achievement or Unit Standards they can complement as a classroom resource. These links are assigned by Royal Society of New Zealand Teacher Fellows who are working during the year with NIWA scientists.
Pete Mason: up to his knees in work
Hydrologist Pete Mason has turned a taste for adventure into a working life that’s taken him from Antarctica to the South Pacific, and from Outback Australia to the Chatham Islands.
New Zealand's diverse seafloor sediments
This stunning poster updates the last New Zealand regional sediment chart (published in 1989) using new multibeam bathymetry as well as archived and previously unpublished distributions of seafloor sediments.
