A six-metre long orange underwater robot is flying through the Kaikōura Canyon for the next month collecting information on how the canyon has changed since the 2016 earthquake.
People along the Kapiti and Wanganui coast may spot NIWA’s research vessel Kaharoa operating close to shore in the next few weeks as scientists carry out a survey of snapper, tarakihi, red gurnard and John Dory.
Our oceans are expected to become more acidic as carbon dioxide concentrations rise. This will likely have impacts on the plankton, which play a major role in ocean ecosystems and processes.
NIWA ocean geologist Dr Joshu Mountjoy explains how the R.V. Tangaroa's multibeam system is used for bathymetric (seabed) mapping, and some of the benefits which come out of this mapping.
NIWA marine geologist John Mitchell gives a brief history of bathymetric (seabed) charting, and how it's been carried out over the last few hundred years. (01:18)
Tagging White Sharks off Stewart Island, NZ Scientists from DOC, NIWA, and the University of Auckland are building a unique picture of New Zealand's great white shark population.
The Antarctic atmosphere is physically and chemically unique and influences all latitudes. The goal of this programme is to improve our understanding of the Antarctic atmosphere's role in global change and its response to that change.
Polar ecosystems face physical constraints that set them apart from their warmer counterparts. The greatest constraint is the impact of prolonged periods of winter darkness and sub-zero temperatures.
Scientists completed a successful three-week field tagging trip in April 2011, where they tagged a record 27 great white sharks around the Titi (Muttonbird) Islands off the northeast coast of Stewart Island.
NIWA Chairman Chris Mace says New Zealand urgently needs a National Oceans Strategy, to sustainably manage and use its extensive marine resources to boost the economy.
"There is huge untapped potential in our oceans and coastal waters, and the Government has clearly indicated their intention to increase the use of these resources. Under the current global economic environment, I think that is prudent. But without an integrated oceans strategy, our ability to sustainably manage those resources will clearly be compromised."
A team of international scientists, led by NIWA Oceanographer Dr Philip Boyd, departs from Auckland on 6 June and sails towards the waters South of New Caledonia this week. They are onboard Research Vessel Tangaroa, for the second leg of the GEOTRACES programme: a ten-year international study of trace elements in the marine environment.
Ground-breaking research by NIWA and The University of Auckland, investigating the annual movements of New Zealand seabirds migrating within the Pacific Ocean, has revealed that populations are genetically distinct, and have been for centuries as a result of their differing migration behavior.
Uses a float and counterweight system to convert water level into an electronic output that can be read by a datalogger. Accurate to within a millimetre over a wide range.
This has 16 analog inputs with an accuracy of better than 0.1% of full scale. You can configure inputs as single ended or differential and select from four input signal ranges.
The Neon Applications software is a suite of software and documentation which allows clients to set up their own Neon system on existing server hardware, or new server hardware located at the client’s premises.
The NRT is a small self-contained unit which connects to sensors, records readings from them and transmits the data to a central server via satellite communications.
The NRT is a small self-contained unit which connects to sensors, records readings from them and transmits the data to a central server via a cellular telephone network.
NIWA Oceanographer Dr Craig Stevens has returned, with stunning images and data, from a successful month-long research trip in Antarctica, where he led a team of international and New Zealand scientists.
A low-cost weather station for gathering accurate weather data. Wind speed and direction, air temperature, relative humidity, barometric pressure and rainfall data can be accessed from a server, via the internet.
This measures rain by the drop as well as by the tradional 'tip'. We can configure it either with an SDI12 serial data interface or an integral logger with cellular communications.
