A workshop to be held in Dunedin next week brings together experts in all aspects of UV radiation and its effects. The workshop is sponsored by NIWA, the SunSmart Partnership, the Ministry of Health, and the Royal Society.
Over three days (19-21 April), presenters will consider such questions as:
New Zealand’s seagrass meadows are important, but threatened, coastal habitats that we still know little about. Scientists from NIWA are undertaking a nationwide survey of these vibrant underwater meadows, to find out more about the life they support and their wider role in the marine ecosystem.
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.
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.
18 December 2005 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.
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.
