Fractional abundances of branched glycerol dialkyl glycerol tetraethers (brGDGT) from the Arid Central Asian Data Base (ACADB) for surface brGDGT samples

This file contains the fractional abundances of the 21 available branched glycerol dialkyl glycerol tetraethers (brGDGT) including the 5-, 6- and 7-methyl isomers. The fractional abundances are given in percentages. For the name of the compounds, the Roman numerals refer to the nomenclature given in De Jonge et al. (2014a). The 5-, 6- and 7-methyl isomer are given with _5Me, _6Me and _7Me respectively.
