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.

Researching NIWA's Antarctic sea ice

NIWA marine physics technician Brett Grant gives a tour of our Antarctic field camp and explains how we are conducting research into sea ice in the coldest place on the planet.

Tangaroa and 44 intrepid voyagers successfully completed the most comprehensive survey of marine life ever undertaken in the Ross Sea region. They returned to Wellington on 20 March after an epic 50-day, 7140 nautical mile voyage, bearing more than 37 000 biological specimens, and images of seafloor communities never seen before.
The focus of the voyage was to survey biodiversity to provide a fuller picture of the Ross Sea ecosystem and what makes it tick.

Sea ice effects on Ross Sea food webs

Scientists from NIWA and the Finnish Institute of Marine Research are using novel ways to explore the effects of sea ice on coastal food webs in Antarctica.
Sea ice is a major driver of polar marine ecosystems, partly through its effect on light levels and, hence, productivity.

Prime Minister Helen Clark last night launched a major New Zealand scientific voyage to Antarctica as part of the Census of Antarctic Marine Life (CAML) and International Polar Year (IPY).

Twenty-six scientists and 18 crew will leave this week on the eight-week voyage aboard RV Tangaroa.

Scott Base, Antarctica
Antarctica is the coldest, windiest and driest continent. Scott Base is New Zealand's permanent Antarctic base. Sited on the coast, temperatures, although very low, are higher than those recorded inland.

Scientists from NIWA have made the first measurements of photosynthesis in the icy gloom of an Antarctic lake floor.

On 27 January 2004 a team of scientists set out from Wellington on board NIWA’s research vessel Tangaroa bound for the Ross Sea in Antarctica.
