Description:
Concentrations of isoGDGTs and brGDGTs, All samples and corresponding depths, ages, lithology (* = generally greener intervals or very small intervals with laminations that were not incorporated into the log of Salabarnada et al., 2018), method used, isoprenoid and branched GDGT integrated values, TEX86, BIT, Methane Index (MI), GDGT-2/Crenarchaeol ratios GDGT-0/Crenarchaeol ratios and GDGT-2/GDGT-3 ratios, and #rings-tetra values. Discarded samples are indicated in the Outlier column. Discards based on BIT and #rings-tetra are indicated with an 'a'. Discarded samples with GDGT-0/Crenarchaeol ratio above 2.0 are indicated with a 'b', those with MI values above 0.3 are indicated with a 'c', those with GDGT-2/crenarchaeol ratios above 0.4 with 'd' and those with ΔRI value above 0.6 with an 'O'. Discarded samples taken from mass waste deposits are underlined.Note that data from mass waste deposits are included in this dataset, but may have to be discarded.
