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

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

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.
Blue Cod
For the first time on a blue cod survey, cameras were fixed to some of the pots to observe the behaviour of blue cod in and around the pots.
Summer Camp - Extreme

NIWA forecast
Scientists, farmers and growers discuss NIWA's new weather forecasting product at Fieldays 2013.
Back to the Future
Dr Katja Riedel and Dr Hinrich Schaefer discuss how NIWA's ice coring work on Taylor Glacier in Antarctica is allowing us to find out about the Earth's atmosphere in the distant past.
