Latest news

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.
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!

Our work

NIWA is conducting a five–year study to map changes in the distribution of plankton species in surface waters between New Zealand and the Ross Sea.
Ocean acidification conditions around the New Zealand coast are being measured to establish baseline conditions and to quantify future change.
Our oceans are expected to become more acidic as carbon dioxide concentrations rise. This will likely have impacts on the plankton, which play a major role in ocean ecosystems and processes.
Where and when do white sharks occur in New Zealand waters, and how can fisheries bycatch be reduced?
