Open wide: Snapper teeth secrets
NIWA and University of Auckland masters student Georgia Third is getting up close and personal with snapper guts and teeth to understand the differences between biologically distinct snapper populations in New Zealand.
Glacier timelines
Once upon a time, long ago, massive glaciers covered our landscape. As they retreat, they leave piles of sediment and rocks behind called moraines that tell an important story of New Zealand's climate history.
Why was 2021 New Zealand’s warmest year on record?
It's official, 2021 was Aotearoa New Zealand’s warmest year on record.
Commercial catch sampling
The Otolith is the earbone of the fish and like the rings on a tree it can tell us about the story of the fish's life.
Dive into the alien world of plankton in the Ross Sea
Plankton are the base of the oceans food web and are vital to our survival. But as our world changes will they be able to continue to play this essential role?
Lauder Atmospheric Research Station
For six decades atmospheric scientists have been making measurements in the middle of nowhere, Central Otago.
Life under the Ross Sea ice
NIWA researchers are using remote underwater cameras to uncover the rich diversity of life under the Ross Sea and they are amazed at what they are finding in these chilly Antarctic waters.
Antarctic science onboard NIWA’s RV Tangaroa
Researchers are working their way through a wealth of new Antarctic marine data after RV Tangaroa successfully completed its five week scientific voyage to the Ross Sea.
Our Climate is Changing
Our climate is changing - we need to act now.
The instruments at work - In the volcano's wake
Our team onboard RV Tangaroa are equipped with all the tech and tools they need to explore the undersea changes caused by the devastating volcanic eruption in Tonga earlier this year.
Mapping the Tongan eruption
The January eruption of the Tongan volcano Hunga Tonga – Hunga Ha’apai triggered tsunamis as far away as the Caribbean. NIWA scientists are onboard RV Tangaroa surveying the ocean around the volcano, working to understand the largest eruption of its kind since 1981 so they can help increase our knowledge about similar volcanoes around the world.
Hazards in the Tasman Sea
You’ll be blown away by what these women in science are up to onboard this RV Tangaroa voyage to the Tasman Sea.
Microplastics: a deeper problem than we thought?
There is increasing global concern about the presence of plastic pollution in our oceans.
X-craft and NIWA collaborate for fisheries rearch.
A six-metre-long autonomous vessel is equipped with artificial intelligence and a range of data gathering equipment, including a battery powered echosounder that can estimate the size of fish populations.
Mapping the oceans through citizen science
The Seabed 2030 South and West Pacific Ocean Data Center is one of four global Regional Centres, each being responsible for data gathering and mapping in their territory.
Seabed 2030 - filling in the gaps
Did you know NIWA is leading a NZ partnership in a worldwide initiative to map the entire globe’s seafloor? Found out more about the Seabed 2030 initiative.
Exploring deep-sea oases
Deep below the ocean surface, life thrives in a world once thought to be inhospitable.
Tropical Cyclone Outlook: November 2021-April 2022
The NIWA and MetService assessment of named tropical cyclone (TC) activity indicates 9 to 12 named TCs could occur in the Southwest Pacific basin between November 2021 and April 2022. The seasonal outlook is for normal to slightly above normal activity in terms of overall named TCs in the region.
