| contents | The file contains Labile (L-pTM), Refractory (R-pTM), and Total (T-pTM) particulate trace metal concentrations of Molybdenum (Mo), Chromium (Cr), Barium (Ba), Tungsten (W), Thorium (Th), and Uranium (U) for marine particle samples collected from the water column of the shelf section and 3-degree latitudinal transect of the GEOTRACES GA08 (R/V Meteor - M121) in the Southwest African shelf region (following Cutter et al., 2010; http://dx.doi.org/10.25607/OBP-2). Particles were collected by filtering seawater through 0.2 µm-pore polyethersulfone (PES) filters in a containerized cleanroom aboard the ship in the field, between the 22nd November - 27th December 2015. Marine particle samples were sequentially leached (following the method of Al-Hashem et al., 2022; https://doi.org/10.1029/2022GB007453, adapted from Berger et al., 2008; https://doi.org/10.1029/2007JC004703), and digested using a strong acid mixture for refractory material (using a method adapted from Cullen and Sherrell, 1999; https://doi.org/10.1016/S0304-4203(99)00060-2) in a land-based clean laboratory at GEOMAR between July 2018- January 2019. Total particulate trace metal concentrations that are reported are the summed concentrations of labile and refractory fractions. Trace metal concentrations were measured by ICP-MS and quantified using external multi-element calibration with standards prepared in a sample-matched matrix (following Cullen et al., 2001; https://doi.org/10.1039/b104398f) between September 2018 - February 2020. |
