Dataset

Comment: 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.
