Chemical composition of sediments from GH80-1 cruise on a carbonate, water and residual materials free basis

The 127 sediment samples of this study (Table XIV-1) were selected on the ship from 17 piston cores and 27 box cores, which were taken by shipboard members from 44 locations along the traverses of GH80-1 cruise. The samples were dried at 70°C, ground, and subsequently split into fractions. One fraction was analysed with automatic X-ray fluorescence spectrometer JOEL-IOOS for Si, Ti, Al, Fe, Mn, Mg, Ca, Na, K, and P. Other fractions were analysed for total water, ignition loss, dissolved chlorine, ferrous iron, and carbonate.
