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.
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 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.
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.
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)
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.
NIWA scientists have worked for many years in Antarctica. These photographs illustrate some of our work in this amazing and scientifically significant place.
Following the Tasman Sea marine heatwave event of 2017-18, this report will help users understand the latest conditions in the ocean and their expected changes over the upcoming weeks.
During the voyage, we collected planktonic protist cells for which DNA will be sequenced for taxonomic identification, but also to understand their physiology through the daily diurnal vertical migration (diel) cycle.

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.
