A global effort by seabird researchers, including those from NIWA, has resulted in the first assessment of where the world’s most threatened seabirds spend their time.
Sadie Mills has come a long way from scaring the inhabitants of Scottish rock pools. Sarah Fraser explains.
A large, orange Scandinavian robot gives NIWA’s marine geologists an in-depth look at changes to the seafloor off Kaikōura.
New Zealanders and Pacific Island communities are on their way to having the most advanced tsunami monitoring system in the world.

Our work

We need information on the food web structures of our marine ecosystems in order to manage the effects on the ecosystem of fishing, aquaculture and mining, as well as understanding the potential impacts of climate variability and change on our oceans. 

Ocean acidification conditions around the New Zealand coast are being measured to establish baseline conditions and to quantify future change.
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.
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.
