See NIWA scientists talking about their work, along with fascinating animations and underwater footage.

Balleny humpback whale research
The region around the Balleny Islands is a known foraging area for humpback whales. Objective one of the Antarctica voyage aimed to determine why the Islands are such a popular spot for humpback whales.
Antarctic trawl nets deep data
NIWA scientists aboard RV Tangaroa have been trawling the central Ross Sea calculating the abundance of the prey species.
Time lapse video of RV Tangaroa moving through icy Antarctic waters
Watch NIWA's RV Tangaroa making its way through icy waters in the Ross Sea, Antarctica.
Pod of Orcas visit RV Tangaroa
NIWA research vessel Tangaroa, down in Antarctic waters, received some welcome visitors yesterday
Singin' the Blues
Antarctic blue whales were severely depleted during the industrial whaling era, when the population declined to only a few hundred individuals. Scientists believe the Antarctic blue whale population has been recovering, albeit very slowly, since the 1960s.
Scientific Diver Training with NIWA
NIWA's diver training course is designed to expose students to some of the most challenging conditions they are likely to encounter working as scientific divers.
Southern right whales filmed near Campbell Island
Footage of southern right whales, filmed near Campbell Island, one of New Zealand's sub-Antarctic islands.
Farming Industry Challenges
Chief Scientist Clive Howard-Williams discusses upcoming challenges for New Zealand's farming industry, and the steps that the industry will need to take to keep our waterways clean.
Constructed Wetlands
Natural wetlands have been called the “kidneys of the landscape” because of their ability to store and transform contaminants before they reach waterways.
Binding Phosphorus
Aquatic pollution specialist Chris Hickey discusses the use of binding agents to reduce phosphorus runoff at the end of farm drainage.
Riparian Zones
Freshwater Ecologist John Quinn talks about improving riparian zones to deal with diffuse pollution in our rural waterways.
Stream Ecology
John Quinn looks at stream ecology as a way of measuring stream health.
Taking water from rivers
Principal Scientist Murray Hicks discusses new modelling technology to assist with making decisions on taking water from natural waterways.
Covered Anaerobic Ponds
Biogas specialist Stephan Heubeck talks about the use of covered anaerobic ponds to mitigate pollution and generate electricity for the farm.
Irrigation Automation
Steve de Lima talks about the automation of irrigation processes in Canterbury and the ability to control flows via mobile phone or tablet devices.
NIWA antarctic buoy deployed
A buoy to measure waves in the Southern Ocean is lowered on to sea ice via a helicopter from research vessel, Aurora Australis.
Ocean Acidification
This video has been produced to highlight ocean acidification as a potential issue affecting the NZ shellfish aquaculture industry
Our World is Changing
Our world is changing - here is some food for thought...
Thin Ice
In late 2013, a group of scientists from NIWA travelled to Antarctica to perform a series of experiments under the sea ice to look at how climate change and ocean acidification could affect this fragile ecosytem.
Ice divers
A specialist dive team venture under the Antarctic sea ice to work on an ocean acidification experiment, and they bring back some breath taking video of the environment along the way.
