Role of Southern Ocean as Earth's carbon sink

Antarctic sea ice: what it is, why it's important, and the difficulty in measuring its extent

Our oceans are expected to become more acidic as carbon dioxide concentrations rise. This will likely have impacts on the plankton, which play a major role in ocean ecosystems and processes.

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.
