Elemental ratios from sediment core MD01-2444 on the Portuguese Margin, Marine Isotope Stage 3 ...
XRF Analysis: Archive halves of sections from Core MD01-2444 were analysed using an Avaatech XRF core scanner at the University of Cambridge. The core surface was carefully scraped cleaned and covered with a 4-mm thin SPEXCertiPrep Ultralene foil to avoid contamination and minimize desiccation. Each...
