Additionally, we highlight the complexity and localised behaviour of recent and shorter timescale Southern Hemisphere Westerlies changes, with implications for future research.

Our results suggest stronger Southern Hemisphere Westerlies at Macquarie Island from ~2500–2300 cal yr. BP and after ~800 cal yr. BP, and relatively weaker Southern Hemisphere Westerlies between ~2300–800 cal yr. BP. Superimposed on this long-term trend are centennial-scale fluctuations.

Here we demonstrate a direct reconstruction method that provides a robust framework for reconstructing past wind variability, with the broader aim of improving our understanding of past Southern Hemisphere Westerlies behaviours.

As an important component of the Earth's system, changes in the Southern Hemisphere Westerlies profoundly impact climate and the ocean-cryosphere-atmosphere domains.

In this research, we used halophilic and halophobic diatoms to reconstruct the Southern Hemisphere variability on subantarctic Macquarie Island during the last 2500 years, by exploiting the wind-driven sea spray and lake conductivity relationship.
