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

Ocean Acidification
The oceans are an important sink for atmospheric CO2, but as they take up increasing amounts of CO2 they are becoming more acidic.
Exploring Antarctic Deepsea Life
Most of the Southern Ocean outside of the narrow Antarctic continental shelf is more than 3000 m deep. This poses a real challenge for scientists studying the assemblages of animals living on the seabed.
Next Stop Antarctica
Our Far South is an expedition that aims to raise New Zealanders' awareness of the area south of Stewart Island. Gareth Morgan, Te Radar, scientists and 50 everyday Kiwis are onboard to learn and then share their experience. This is the first video produced by them, showing some of the highlights of the trip so far.
Current and Future Management of the Toothfish Fishery
NIWA fisheries scientist Dr Stuart Hanchet explains what makes the Antarctic toothfish fishery one of the best managed fisheries in the world.
Ecosystem Effects and Mitigation of the Toothfish Fishery
NIWA fisheries scientist Dr Stuart Hanchet describes the guiding principles that CCAMLR (the Convention on the Conservation of Antarctic Marine Life) applies to the Antarctic toothfish fishery.
The Antarctic Toothfish Fishery
Antarctic toothfish are fished using longlines in southern Antarctic waters. NIWA fisheries scientist Alistair Dunn describes the history of the fishery and how it has been monitored.
Southern Ocean Productivity
Phytoplankton – microscopic plants that drift in the sunlit waters of the world's oceans – are the engine that drives all of Antarctica's marine food webs.
Iron Fertilisation
Iron dissolved in the ocean is an important trace nutrient for phytoplankton – the microscopic plants that support marine food webs.
Phytoplankton and Climate Change
NIWA biological oceanographer Dr Philip Boyd explains how the Southern Ocean plays a key role in controlling the world's climate, by drawing large amounts of CO2 from Earth's atmosphere into the ocean depths.
Seabird Diversity in the Southern Ocean
The New Zealand archipelago, particularly its subantarctic islands, is a global seabird hotspot. It's home to 25 per cent of the world's breeding seabird populations and a very diverse array of penguin, albatross, petrel and shearwater species.
Subantarctic Oceanography
NIWA physical oceanographer Dr Mike Williams talks about the world's largest current – the Antarctic Circumpolar Current (ACC) – and its influence on the 'oceanography' (ocean characteristics) south of New Zealand.
Antarctic Seabed Biodiversity
It's a common myth that the oceans surrounding Antarctica hold the most diverse array of animals on earth, but they are home to a collection of species found nowhere else.
Antarctic Coastal Marine Life
Dr Vonda Cummings, benthic ecologist at NIWA, explains the special characteristics of seafloor communities living in Antarctica's coastal waters and the importance of understanding what makes them tick.
Southern Ocean Gas Exchange
The Earth's oceans – particularly the Southern Ocean – play an important role in absorbing carbon dioxide (CO2) and other trace gases from the atmosphere.
The Iron Hypothesis
NIWA biological oceanographer Dr Philip Boyd explains the iron hypothesis: what it is, its history, and some recent experiments in the Southern Ocean.
Antarctic Sea Ice
The sea ice that forms around Antarctica in winter effectively doubles the size of the continent, and its extent has increased over recent years.
Antarctic & Southern Ocean Climate
NIWA climate scientist Dr James Renwick explains what's unique about the Antarctic/Southern Ocean climate system, the forces that influence it, and how it's changing.
Kaikoura Canyon Seabed Life
The video represents a number of clips that have been spliced together to illustrate the abundant life associated with the muddy seabed sediments in Kaikoura Canyon at 1000m.
Dr Philip Boyd on geoengineering
NIWA's Dr Philip Boyd on geoengineering and the research which won him and a team of scientists from NIWA and Otago University the 2011 Prime Minister's Science Prize.
Desmonema gaudichaudi jellyfish
On Friday November 11th, a large spotted jellyfish was seen floating just off the coast in Evans Bay, 50 m north of the NIWA campus at Greta Point.
