Antarctica

Latest news

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.
After travelling almost 12,000km in the past six weeks, a group of scientists returns to Wellington at the weekend with new knowledge about life in the Ross Sea of Antarctica.

Our work

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.
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.

Acidification of the world’s oceans from rising atmospheric carbon dioxide levels reduces the availability of carbonate required by some marine organisms to build shells and skeletons, and potentially affects their ability to maintain existing structures.

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.

NIWA’s research vessel Tangaroa sets off for a six-week voyage to Antarctica in February. Six of those aboard explain what they’re doing, what they’re worried about and the one thing they wouldn’t be without.
RV Tangaroa is undertaking a six-week voyage to Antarctica and the Southern Ocean between 5 February and 21 March 2018 with scientists from NIWA and the University of Auckland.
A dramatic change in sea ice this year is likely to hamper a NIWA-led research project aiming to better understand how ice shelves will melt as the ocean warms.
The Deep South National Science Challenge is one of New Zealand’s most audacious collaborative projects in recent times.
Pioneering NIWA scientists are returning to the cold continent in October, this time to focus on the seabed.
The Ross Sea Marine Protected Area (MPA) in the Southern Ocean will help further research into the ecology of Antarctic toothfish.

Inputs into stock assessment

Top of Natalie Robinson’s to-do list right now is to work out exactly what she’s brought back from Antarctica.
NIWA scientists are this week making the final preparations for one of the organisation’s busiest summers at Antarctica.

Sea ice-based toothfish surveys have been carried out in McMurdo Sound since 2014.

A bibliography of some of the journal papers and CCAMLR Working Group papers published about the toothfish fishery.

The fishery is managed differently depending on the region and specific environmental protection and fishery management objectives in the region.

Find out about the role of toothfish in the ecosystem and the potential effects of fishing.
