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

Our World
Compiled by NIWA from the United Nations report "Keeping Track of Our Changing Environment: From Rio to Rio+20 (1992-2012)".
Ocean acidification
Otago water shows how the ocean is changing.
Journey Across an Underwater Landscape
The diverse communities of New Zealand's seamounts. On show at the Deep NZ: Our underwater wilderness exhibition at Te Papa 2012/2013.
Echo, Echo: Scanning the Seafloor on R.V. Tangaroa
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.
Seabed Frontier: A Brief History of Bathymetry
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) 
Pearse Resurgence Dive
Australian cave divers exploring the Pearse Resurgence, a cave system near Nelson, in search of samples of stygofauna.
Vent and seamount fauna - Tangaroa Seamount
A collection of images of some of the chemosynthetic barnacles, mussels, and shrimps on Tangaroa Seamount. The footage and specimens confirmed active hydrothermal venting.
Big Fish, Calm Sea - White Shark Tagging off Stewart Island
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.
Science in the City - overview
The Science in the City event, held at The Cloud in Auckland on the 12th of April, was a great success. This video shows some of the science that was on display. 
Biodiversity in the Kermadecs
This amazing footage was captured at the Kermadec Ridge in 2011, by NIWA's Deep-Towed Imaging System (DTIS). 
ROV Fiordland footage
Never before seen footage. This amazing footage was captured by our ROV in the Fiordland Sounds.
Climate Change and Deepsea Life
Dr Dave Bowden outlines concerns over the impacts of climate change on deepsea life in Antarctic waters.
Southern Blue Whiting Fishery
NIWA fisheries scientist Dr Stuart Hanchet describes the history and management of the southern blue whiting fishery, centred around New Zealand's subantarctic islands.
Sea Ice and Climate Change
Dr Mike Williams, physical oceanographer at NIWA, explains the importance of Antarctic sea ice in the Earth's ocean and climate systems and how they may be affected by climate change.
The Microbial Loop
The microbial loop refers to the small microscopic organisms in the ocean – viruses, bacteria, the small phytoplankton and microzooplankton – and the relationships between them.
Climate Change and the Microbial Loop
NIWA biological oceanographer Dr Julie Hall explains how increased sea temperatures are predicted to increase stratification of the ocean, creating a disconnect between the surface waters and deep ocean.
Antarctic Coastal Marine Life in a Changing Climate
NIWA marine ecologist Dr Vonda Cummings discusses the likely effects of climate change on marine invertebrates living on the seafloor of the Ross Sea coast.
Antarctic Climate Change
NIWA climate scientist Dr James Renwick explains what changes are occurring in the Antarctic in response to climate change and what's likely to happen in the future.
Antarctic Marine Food Webs
NIWA biological oceanographer Dr Matt Pinkerton discusses the complexities of Antarctic marine food webs, the uniqueness of many of Antarctica's marine animals and the extreme adaptations they display.
The Decline of Subantarctic Wildlife
Populations of rockhopper penguins, elephant seals, and grey-headed albatrosses in the subantarctic have declined quite markedly in recent decades.
