  • The formation and circulation of Antarctic Intermediate Water has varied over glacial–interglacial timescales. A neodymium record from the Atlantic Ocean basin suggests that changes in circulation may have been driven by changes both in Antarctic Intermediate Water formation in the Southern Ocean and in the strength of North Atlantic meridional overturning.

  • Reconstructions of land and ocean temperatures over the past 18,000 years in the high southern latitudes have shown conflicting trends. Analyses of temperatures on Campbell Island, south of New Zealand, confirm this behaviour, and lead to the suggestion that it reflects changes in the position and intensity of the westerly winds.

  • Dust deposition brings iron that fuels ocean productivity, a connection impacting climate over geological time. Here the authors use sediment cores to show that in contrast to dynamics today, during the last glacial maximum westerly winds shuttled dust from Australia and South America around Antarctica and into the South Pacific.
