This data set includes biogeochemical proxy data analysed on sediment core TAN1106-28 in 2021 at the University of Tasmania, The Australian Nuclear Science and Technology Organisation, National Taiwan University, and the University of Southampton. This sediment core was collected in 2011 by the RV Tangaroa, in the Solander Trough, south of New Zealand (-48.372°S, 165.659°E). The data spans from 71–0 ka, and is comprised of sea surface temperatures, thorium normalised fluxes of iron, lithogenic material, total organic carbon, chlorins, CaCO3, and excess barium, as well as formanifera-bound nitrogen isotopic compositions, authigenic uranium and excess manganese concentrations, and Benthic-Planktic 14C offsets (yrs).
