support resilience to climate change
-
increase understanding of land and marine geological processes
-
support the sustainable use of fisheries, aquaculture and other marine resources
-

-
enhance resilience and risk management through advanced technology, AI, machine learning and data science
- support economic growth and resilience of Māori and Pacific Island nations.
Earth Sciences New Zealand is currently operating as two business units. The NIWA business unit specialises in atmospheric, freshwater and marine research while the GNS Science business unit’s expertise is in surface and subsurface of the Earth. We have about 1,200 staff across both business units, spread throughout the country.
This website gives an overview of Earth Sciences New Zealand and directs you to content on each of the founding organisation’s websites. Over time, this material will be combined and updated on one website.
