Antarctica

Latest news

NIWA’s flagship research vessel Tangaroa leaves soon on a six-week voyage to Antarctica, making it one of the few full scientific expeditions to the continent since the global outbreak of COVID-19.
At the bottom of the Southern Ocean, near Cape Adare in East Antarctica, lies an undersea ridge which until this month was only known by its co-ordinates: -71.2132 latitude, 172.1649 longitude.
Five specialist NIWA divers were left ‘gasping’ during their recent plunge under the ice near Scott Base.
New measurements from the ocean under the centre of the Ross Ice Shelf have significantly improved our understanding of the complex processes that drive melting in Antarctica.

Our work

We don’t clearly understand the ecological effects of commerical toothfish fishing in the Ross Sea region. To improve our knowledge, we conducted a survey of demersal (bottom-dwelling) fish species on the Ross Sea slope - particularly grenadiers and icefish - during the 2015 Antarctic Ecosystems Voyage.
NIWA’s Antarctic fisheries research is allowing us to investigate possible effects of the longline Antarctic toothfish fishery on the toothfish population and on the local ecosystem.
Climate Present and Past is a core-funded project under NIWA's National Climate Centre. It aims to explore historical climate data and track past changes in climate through a range of approaches.
The Southern Ocean is under-sampled. Data collected continuously during the Antarctic Ecosystems Voyagehelped fill an important knowledge gap about oceanographic and atmospheric processes in this important region.

The clear sky and exceptional visibility made our approach to Woods Bay very memorable with Mount Melbourne dead ahead and Mount Murchison on our starboard beam.
Numerous sightings of minke whales today while target identification mid-water trawls were being made on krill and fish layers beneath Tangaroa.
Day 34 of the Ross Sea Life in a Changing Climate (ReLiCC) 2021 voyage on RV Tangaroa. We are back in New Zealand waters and due to arrive in Wellington on the morning of Monday 15 Feb.
Glen Walker is the bosun aboard NIWA’s research vessel Tangaroa currently exploring the waters around Antarctica. His reading list is exclusively sea disaster stories.
It is interesting to watch all of the pieces of our science story come together with each day’s water sampling and our long term experiments.
We are now four weeks into the Ross Sea Life in a Changing Climate (ReLiCC) 2021 voyage on RV Tangaroa and our time in the Ross Sea is rapidly coming to an end.
Antarctica is an incredibly pristine place; we are here to do good science and leave no trace. So, you can imagine my horror as I watched my camera start to float away from the boat.
Sitting in the library of the R.V. Tangaroa, I’m contemplating the (almost) three weeks spent at sea. From the nauseating swell of the ferocious fifties to the mornings when I’ve woken to beautiful vistas of Antarctic mountains.
Day 20 and we are now more than halfway through the Ross Sea Life in a Changing Climate (ReLiCC) 2021 voyage on RV Tangaroa.
Tue 19th: At 00:00 this morning we came across an extremely large tabular iceberg. It was easily picked up on the ship’s radar but due to the foggy conditions was only visible at a range of 1.7 miles.
Day 13 of the Ross Sea Life in a Changing Climate (ReLiCC) 2021 voyage on RV Tangaroa finds us close to Cape Adare on the tip of the Antarctic continent. We’ve had a busy and icy week.
NIWA’s flagship research vessel Tangaroa leaves soon on a six-week voyage to Antarctica, making it one of the few full scientific expeditions to the continent since the global outbreak of COVID-19.
RV Tangaroa is undertaking a 45-day voyage to the Southern Ocean and Ross Sea in early January and returning by February 16, 2021.

The rich diversity of marine life near Scott Base in Antarctica has stunned scientists diving under the ice to set up environmental monitoring sites.
The New Zealand ship Janas has recently returned from a six-week winter research voyage to the Ross Sea where scientists made the first observations of developing Antarctic toothfish embryos.
While most New Zealanders were settling into their summer break, some scientists were double-checking their survival gear before heading to work deep in the Southern Ocean.
Part of the world’s largest ice shelf is melting 10 times faster than the overall average and solar-heated waters beneath the ice shelf are to blame, NIWA research has found.
