Antarctica

NIWA marine ecologists, including specialist divers, are heading south shortly for the second stage in a range of experiments that take place under the ice in Antarctica.

NIWA scientists have made a breakthrough in understanding one of the key processes driving changes in sea ice.

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.

The Southern Ocean has a strong influence on New Zealand and global climate. To understand how the oceans have changed over 1000s of years we use sediment archives from the seafloor.

This research project focusses on modelling atmospheric chemistry and climate from the surface to the top of the stratosphere, using sophisticated chemistry-climate models.
