An international team of marine scientists returns to the Chatham Islands next week hoping to fit satellite tags on up to 13 great white sharks. The tags will allow the scientists to track the sharks' movements for up to nine months.

The number of known offshore earthquake sources in the Bay of Plenty has been drastically revised.

A high-powered scientific panel will be meeting in Alexandra next week to consider the environmental effects of ozone depletion.

A NIWA scientist has used sophisticated sonar technology to reveal a ghost-like image of the Mikhail Lermontov lying in its watery grave in the Marlborough Sounds.

Two new scientific papers describe the potential severity of waves from locally-generated tsunamis off the Kaikoura coast.

A major collaborative effort involving French and New Zealand researchers will be delving in mud beneath the seafloor this month, looking for clues about past and future climate change and its various effects on the seafloor.

Scientists from NIWA have developed the first fisheries assessment for Antarctic toothfish, and the first for any exploratory Antarctic fishery. The 2005–06 quota for the Ross Sea Antarctic toothfish fishery, which opened on 1 December, has taken account of this new assessment.

The multibeam acoustic mapping was conducted by NIWA, with funding from the Foundation for Research, Science & Technology.
NIWA marine geologist, Dr Helen Neil, says the existence of the canyons has been known for a long time, but until now they've been drawn as more or less straight lines on the map.
'What we've found is that the canyons and channels are incredibly complicated. Near shore, the upper reaches meander over a 'river' bed up to 20 kilometres wide. Further out to sea, the channel is more than 1000 metres below the surrounding seafloor in places.

Secondary school students from the Hutt Valley have been taking part in a global experiment to help forecast the climate later this century.

It may be a massive new car carrier, but the TransFuture 5 is also a platform for scientific research into atmospheric pollution across the Pacific.

East Coast farmers have improved their resilience to climate extremes, according to new research.

Climate scientist Doctor Jim Renwick of NIWA has been awarded the Kidson medal by the Meteorological Society at the Royal Society of New Zealand's Awards held at Te Papa on the 16th of November.

Two fossils discovered in the Ormond Valley, near Gisborne, have been identified as a mysterious extinct native fish, the grayling or upokororo. They represent the first known fossils of New Zealand grayling.

Most people wouldn't think of a science research company as a top performer in the business environment, but take a look at NIWA.

A 28-metre research vessel from NIWA will spend the next four and half months deploying ocean-profiling Argo floats across the Pacific.

Scientists from NIWA will be diving in Waikawa Marina, near Picton, on Friday 14 October to check for the presence of an invasive sea squirt, known as the clubbed tunicate (or Styela clava). The work is being conducted for Biosecurity New Zealand so that they can assess the need for further investigation.

Scientists from NIWA are diving in Waitemata Harbour to establish precisely how far an invasive sea squirt, known as the clubbed tunicate (or Styela clava), has spread.

Scientists at NIWA will shortly begin investigations into what is causing blue-green algae blooms in the country’s most iconic lake.

Glaciers in New Zealand’s Southern Alps gained ice mass again in the past year. Fifty glaciers are monitored annually by the National Institute of Water & Atmospheric Research (NIWA).

A paper to be published in the prestigious science journal, Nature, this week offers a rare piece of good news on climate change but signals that the atmosphere may be more variable than previously suspected.
