The dataset comprises of updated proxy data from the Emerald Lake sediment record on Macquarie Island. Core scanning (ITRAX XRF) and multispectral data (SPECIM) originally published in Saunders et al. (2018) have been updated to the 2020 radiocarbon calibration curve. Updates are published in:
Heredia Barión P, Roberts SJ, Spiegel C, Binnie SA, Wacker L, Davies J, et al. (in review) Holocene deglaciation and glacier readvances on the Fildes Peninsula, King George Island, NW Antarctic Peninsula. The Holocene. https://doi.org/10.31223/X59S7S
