Ozone depleting substance found to be rising
Measurements made at NIWA’s atmospheric research laboratory at Lauder are a key component in an article in the latest edition of one of the world’s most prestigious scientific journals, Nature. The international team of scientists, including NIWA researchers, Dan Smale and John Robinson, based their findings on measurements from a network of stations across the globe, including Lauder ...

Ozone depletion far greater without Montreal Protocol, study shows
NIWA atmospheric scientist Dr Richard McKenzie co-authored the paper with British and Dutch scientists, which is published in Nature Communications this week. Dr McKenzie, whose contribution focused on the ultraviolet radiation calculations, said the paper showed that if allowed to continue unchecked, the ozone hole would have grown by 40 per cent by 2013, which would have contributed to further ...

Algae experts to meet in New Zealand
How can we turn seaweed into biofuels? Can we use seaweed to reduce greenhouse gas emissions? Can we stop the spread of didymo in New Zealand? These are some of the questions that will be addressed at the 5th Asian Pacific Phycological Forum, being held in Wellington next week. Phycology is the study of algae, including seaweeds. Around 250 scientists, technologists, resource managers, and ...

20 years of monitoring provides insight into New Zealand`s river water quality
Two decades of monitoring of river water quality by NIWA has provided important information that is helping to care for New Zealand’s iconic rivers. More than 18 000 river water samples have been collected by New Zealand’s National Rivers Water Quality Network (NRWQN) over the past 20 years to monitor river conditions. The Network, which was set up to detect trends and conditions in water ...

NIWA scientists head to Antarctica
More than a dozen NIWA scientists are heading to Antarctica in the next couple of months as the crucial weather window opens for the summer season of research above, on and under the ice. It's a busy time for the scientists who need to make the most of the coming months when the harsh environment is at its most hospitable. The largest NIWA effort this year involves seven staff conducting marine ...

NIWA scientists working under the ice in Antarctica
NIWA marine ecologists, including specialist divers, are heading south shortly for the second stage in a range of experiments that take place under the ice in Antarctica. The experiments involve divers placing specially made chambers on the underside of the ice at Granite Harbour to measure the effects of ocean acidification and warming on sea ice flora and fauna. In two weeks time, an ...

Scientists assess earthquake potential of faults close to West Coast
Seismic research by NIWA scientists off the West Coast of the South Island has identified faults capable of causing earthquakes with magnitudes of up to 7.8. Their work in reassessing the faults will be important for updating the New Zealand National Seismic Hazard Model which combines historic and prehistoric earthquake information to estimate how often earthquakes have occurred and where. ...

Where there’s smoke, there’s air quality scientists
During September, NIWA staff installed temperature sensors in 14 homes in the North Canterbury town to detect when the occupants were using their woodburners. At the same time six prototype low-cost dust sensors, called ODINs or Outdoor Dust Information Nodes developed by NIWA, were installed on lamp posts around Rangiora to test their robustness and data quality. If successful, air quality ...

Tonga eruption caused fastest ever underwater flow
NIWA and the UK’s National Oceanography Centre (NOC) say that the flows travelled at speeds of up to 122km/hour – up to 50% faster than any other recorded. This new analysis, made possible by the NIWA-Nippon Foundation Tonga Eruption Seabed Mapping Project (TESMaP), comes after earlier results showed the eruption of Hunga Tonga–Hunga Ha’apai remobilised a staggering 10km3 ...

Eels sharing home win photographic competition
A photograph of two moray eels sharing an underwater crevice has taken out the judges' choice award at NIWA's annual photograph competition announced last night. The eels were photographed by Auckland-based scientist James Williams near an underwater cliff at the Mokohinau Islands, off the northeast coast of the North Island. Each year NIWA holds a photographic competition for it staff, many of ...

Antarctic visit to study sea ice
Scientists flew to New Zealand’s Scott Base, on the first post-winter Antarctica New Zealand flight last week, to study the growth and thickness of winter coastal sea ice in McMurdo Sound. The scientists, from the National Institute of Water & Atmospheric Research (NIWA) and Otago University, are spending six weeks on the ice doing training, and setting up a pilot study, for an eight month ...

Freshwater scientists host citizen science workshop
If you're keen to join the growing citizen science movement and interested in your local waterways, come along to a free workshop in Christchurch at the weekend. The workshop, supported by NIWA and run by the NZ Hydrological Society, Nature Watch NZ and the Styx Living Laboratory Trust, will feature demonstrations and hands-on opportunities for people to try out some of the scientific methods ...

NIWA trials new generation air quality sensors
For the past 12 months NIWA has been testing a prototype low-cost dust sensor package called ODIN, or Outdoor Dust Information Node. The first field trial is about to get under way in Rangiora, North Canterbury. Air quality scientist Dr Ian Longley says this new generation of low-cost sensors has the potential for communities to observe, understand and control their local air quality in a much ...

Tsunami warning
The warnings apply to the East Cape, Chatham Islands, Coromandel and Banks Peninsula. The warning was issued at noon today and advised people in affected areas to stay out of the water, off beaches and shore areas and not to go sightseeing. Unusually strong currents and unpredictable water flows near the shore could be expected in the affected areas, MCDEM said. Further information and updates ...

New Zealand’s glaciers continue to show significant ice loss
New Zealand’s glaciers are showing the lowest total ice mass on record and most are continuing to shrink at a rapid rate. Research released by the National Institute of Water & Atmospheric Research (NIWA) shows the Southern Alps glaciers have lost 2.5 km³ (2.2 billion tonnes) of permanent ice from April 2007 to March 2008, the fourth highest annual loss since monitoring started. The 2008 ...

New Zealand glaciers shrinking
New Zealand’s glaciers are shrinking and twelve of the largest glaciers in the Southern Alps are unlikely to return to their earlier lengths without extraordinary cooling of the climate. Research released by the National Institute of Water & Atmospheric Research (NIWA) today shows that the volume of ice in the Southern Alps has reduced by about 5.8 cubic kilometres, or almost 11%, in the ...

Powerful replacement in works for climate-modeling computer
One of the most powerful computers in the world dedicated to climate change, weather and other earth science research will be replaced in 2017 by an even faster machine, officials announced Monday. The Yellowstone supercomputer in Wyoming currently ranks among the 60 fastest in the world. The new supercomputer, to be named Cheyenne, will be at least 2 1/2 times more powerful, the National Center ...
