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.

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.

Taking the pulse of Antarctica’s ocean ecosystem
Niwa scientists have anchored an echosounder to the sea floor of Terra Nova Bay that could reveal the mystery of silverfish reproduction under the Antarctic ice.
