Proxy data from the Emerald Lake sediment record on Macquarie Island.

The dataset comprises of proxy data from the Emerald Lake sediment record dating back to 12.1ka BP were extracted on Macquarie Island. Three independent methods to reconstruct past changes in Southern Hemisphere Westerly wind (SHW) intensity. Core scanning (ITRAX XRF) and multispectral data (SPECIM) originally published in Saunders et al. (2018) have been updated to the 2020 radiocarbon calibration curve.
