Recently, Australian and New Caledonian shark scientists downloaded data from acoustic receivers deployed off the east coast of Australia and in the Coral Sea and discovered that great white sharks acoustically tagged in New Zealand had been visiting.
NIWA's has mapped the seabed off the coast of Otago, revealing the structure of nine canyons in the Great South Basin. This survey is providing new information about geological processes in the region as well as clues to what types of life might exist on the seafloor.
Scientists have discovered that our big birds take long winter holidays overseas. The native Campbell Albatross take off to South Australia, and the Grey-headed Albatross goes further afield to an area 7,000 km from Campbell Island, in the Indian Ocean to the west of Australia.
NIWA's research vessel Tangaroa recently returned from a 3-week voyage, with pictures (see gallery at bottom of article), film footage and samples of new discoveries from the deep-sea floor, including footage of a new hydrothermal vent on an undersea volcano.
New Zealand's largest research vessel Tangaroa sets off today to map, in high resolution detail, the southern Hikurangi Margin - a vital area of seabed off the east coast of New Zealand.
The voyage is part of the Ocean Survey 20/20 project, a 15-year Government project, established in 2004, to survey and explore New Zealand's oceans, to better manage and sustainably develop their resources.
Scientists have just completed a successful trip to Stewart Island, tagging 23 great white sharks. The sharks were tagged with acoustic and popup tags, and filmed underwater for photo-identification purposes. The tags and photos will allow scientists to investigate the sharks' habitat and behaviour, and to determine the periods during which they inhabit locations such as Stewart Island.
Flying above the New Zealand coastline on cloudless days, you can sometimes see plumes of material-laden river water, much of it containing sediment from land runoff. Understanding where this material ends up will help assess the land use impacts on our vulnerable coastal ecosystems, and guide mitigation measures to reduce those impacts.
Ever wondered what that brownish foam is that you sometimes see clinging to sandy beaches? It's easy to think the foam is a sign of pollution, but in fact it's a natural phenomenon associated with certain kinds of beaches, and the tiny organisms that live there.
Fifty intrepid travellers set off from Bluff tomorrow, onboard the Spirit of Enderby, a Russian ice-strengthened ship, destined for Antarctica and the sub-Antarctica. Organised by Dr Gareth Morgan, the Our Far South voyage aims to raise New Zealanders' awareness of this unique area.
The broadnose sevengill shark, Notorynchus cepedianus, is named descriptively after – wait for it– its broad snout and seven gill slits! Interestingly, most shark species only have five gills. The broadnose sevengill is one of New Zealand's more common inshore sharks.
