This data set is based on a peat sediment core from near the summit of North Head plateau on Macquarie Island. This core is designated as NHP in these notes. NHP is a 291 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 17.0 cm dated back to ca. 1920. Spreadsheet details 1. Notes – information on the sediment core and description of each data worksheet 2. NHP_210Pb_data – 210Pb data (dating the 20th century) 3. NHP_14C_data – Radiocarbon data (dating material older than the 20th century) 4. NHP1_u-XRF – µ-XRF data for the top core 5. NHP2_u-XRF – µ-XRF data for the middle core 6. NHP3_u-XRF – µ-XRF data for the bottom core Fieldwork conducted in February 2018 Analyses conducted from February 2020 to October 2020
