Glycerol dialkyl glycerol tetraethers in the Padul palaeolake record (Sierra Nevada, southern Iberian Peninsula) for the last 36 kyr
This data file contains the total organic carbon (TOC) content and the distribution of isoprenoid and branched glycerol dialkyl glycerol tetraethers (isoGDGTs and brGDGTs, respectively) from the Padul palaeolake record (Padul-15-05 sediment core) covering the last 36-4.7 kyr. BrGDGTs-based indices (...
