This interactive graphic shows how NIWA's work extends from the top of the atmosphere to the bottom of the ocean.

The most detailed seafloor mapping of a coastal region off New Zealand has been completed in Marlborough.
A decade of scientific research into how ocean acidification is affecting New Zealand waters has led to far greater understanding of the vulnerability of our marine ecosystems, according to a newly published review.
The world’s oceans are acidifying as a result of the carbon dioxide (CO2) generated by humanity.
Ocean acidification conditions around the New Zealand coast are being measured to establish baseline conditions and to quantify future change.
It has been another amazing week here on the Tangaroa. On Saturday we saw Antarctica which was an absolutely breath-taking experience that I’ll remember for the rest of my life!

Interest in offshore petroleum and minerals exploration is growing rapidly as investors identify the potential economic returns from New Zealand’s rich marine resources. The challenge for management agencies and scientists is to facilitate development of this natural wealth while ensuring environmental sustainability is not compromised.

Scientists from the Australian Antarctic Division explain the blue whale research they are leading onboard the New Zealand-Australia Antarctic Ecosystems Voyage 2015.
NIWA voyage leader Dr Richard O’Driscoll updates the Tangaroa’s encounter with the planet’s largest living beings – the Antarctic blue whales – and discovers what’s on their menu.
The first objective of the New Zealand- Australia Antarctic Ecosystems Voyage was successfully achieved with the completion of the research at the Balleny Islands.
Ocean Acidification

This video has been produced to highlight ocean acidification as a potential issue affecting the NZ shellfish aquaculture industry. The video is a direct result of the collaborative New Zealand-United States workshop 'Future proofing New Zealand’s shellfish aquaculture: monitoring and adaptation to ocean acidification', organised by NIWA, MPI, Cawthron Institute and US colleagues in December 2013. Featured in the video are scientists, US and NZ industry representatives, as well as officials from the funding agencies MPI, MBIE and the US Embassy.

Organising Team:
Anna Crosbie (MPI), Norman Ragg (Cawthron), Vonda Cummings and Di Tracey (NIWA), Todd Capson (US Sustainable Fisheries organisation). Video produced by Dave Allen (NIWA)
