Brief description

This data set is based on a peat sediment core from near a small, unnamed lake on Macquarie Island. This core is designated as PLK1 in these notes.

PLK1 is a 136.9 cm peat sediment core, collected in three sections 2018. It was analysed with a micro x-ray fluorescence (µ-XRF) core scanner at the Australian Nuclear Science and Technology Organisation (ANSTO), then sampled at 0.5 cm increments. It was dated using 210Pb (ages calculated using the constant flux, constant sedimentation model) and 14C. Based on 210Pb dating the upper 18.0 cm dated back to ca. 1900.
