Dataset is comprised of X-ray fluorescence (XRF) data from sediments from International Ocean Discovery Program (IODP) Expedition 382, Site U1534, South Falkland Sediment Drift, 53.18967 S, 58.76083 W (605 m water depth). The sediment cores were collected from 3 holes using the advanced piston corer onboard RV Joides Resolution from site U1534 between 29/03/2019 and 02/04/2019. XRF data was collected using the XRF Core Scanner III (AVAATECH Serial No. 12) at the XRF Core Scanner Lab at the MARUM (Center for Marine Environmental Sciences, University of Bremen, Germany), March-May 2021. The data were collected as part of a project aiming to investigate the sensitivity of the Atlantic Meridional Overturning Circulation to variability in Pacific-Atlantic connectivity via the 'cold water route'. Dr Victoria Louise Peck was the principle investigator for this project. Funding provided by NERC UKIODP moratorium grant NE/T010908/1

This dataset comprises data from a series of peat cores extracted from Site KER3, Kerguelen Island. Data includes: 1 mm-scale (contiguous) spectra count per second (cps) chemical element data from composite downcore X-ray Fluorescence Core Scan (XRF-CS) geochemical data, ~1 cm-scale (interval) Inductively Coupled Mass Spectrometry (ICP-MS) geochemical and subsample data, 5 mm-scale (interval) Multi Sensor Core Logger (MSCL) data, and sedimentological parameters. The data set was used in conjunction with other peat core records from five sites on four sub-Antarctic Islands for calibration of XRF-CS to ICPMS to quantify high resolution XRF-CS to enable dust flux calculations at high resolution. This research was funded by NERC Standard Grant NE/K004514/1 (DAH, SJR). Field programmes were supported by the British Antarctic Survey (CASS126, Bird Island), NERC (Late Quaternary changes in the Westerly Winds over the Southern Ocean NERC PhD 1772184), Instituto Antartico Chileno (Isla Hermite), South African National Antarctic Program (Marion Island), and the Swiss Polar Institute, Antarctic Circumpolar Expedition (ACE09, Marion Island, Iles Kerguelen). The NERC/SUERC AMS (Accelerator Mass Spectrometry) Radiocarbon Facility, the LMC-14 staff (Laboratoire de Mesure du Carbone 14, Paris Saclay) and the ARTEMIS national instrument (LSCE, CNRS-CEA-UVSQ-IRD-IRSN-MC) provided some of the radiocarbon dates.
