Scientists from NIWA are undertaking a unique experiment with Surf Life Saving New Zealand to investigate the behaviour of rips. The experiment, scheduled for 22 January, will follow a surf lifeguard carried along by rips at Raglan beach.
A 4.4 metre female great white shark has set a new distance record for a New Zealand shark by swimming over 3000km to the tropical waters of the southern Great Barrier Reef, Australia. The shark, nicknamed Kerri, has provided the first evidence that New Zealand great whites do in fact travel to Australia.
Two hundred of the world’s leading marine biologists will gather in Auckland from 14-16 November to share the latest insights on sea-life from the poles to the tropics. This major meeting of the global research programme, the Census of Marine Life, is being jointly hosted by NIWA and The University of Auckland.
NIWA is leading a new three-year research project to investigate the contaminant levels and risk to Māori health associated with ‘wild kai’ – food gathered from the sea (kai moana), rivers (kai awa), and lakes (kai roto).
Research funded by the Australian Government will investigate tsunamis on the west coast of New Zealand to help understand how much risk they pose to Australia.
Although the recent earthquakes south of New Zealand caused little more than a ripple on Australian shores, researchers estimate that more than 300,000 lives and property worth more than $150bn on the NSW coast are vulnerable to large tsunamis. At present, however, scientists do not have a clear idea about how often such tsunamis occur and how big they might be.
Scientists have discovered that some deepsea sponges have growth bands that, like tree rings, can reveal past environmental conditions. The bands show that, far from being a constant environment, the deep ocean experiences changes akin to seasons.
Weak La Niña conditions are likely to alter the chances of tropical cyclone activity for several tropical South Pacific countries over coming months. NIWA and Pacific meteorological organisations are urging island communities to remain prepared as there is always a risk.
