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.
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.

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.
Natural wetlands have been called the “kidneys of the landscape” because of their ability to store and transform contaminants before they reach waterways.
Aquatic pollution specialist Chris Hickey discusses the use of binding agents to reduce phosphorus runoff at the end of farm drainage.
Freshwater Ecologist John Quinn talks about improving riparian zones to deal with diffuse pollution in our rural waterways.
John Quinn looks at stream ecology as a way of measuring stream health.
Principal Scientist Murray Hicks discusses new modelling technology to assist with making decisions on taking water from natural waterways.
Biogas specialist Stephan Heubeck talks about the use of covered anaerobic ponds to mitigate pollution and generate electricity for the farm.
Steve de Lima talks about the automation of irrigation processes in Canterbury and the ability to control flows via mobile phone or tablet devices.

Our world is changing - here is some food for thought...
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.
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.
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.
