We report the peak areas for isoprenoid-GDGTs, branched-GDGTs and H-GDGTs, allowing GDGT indexes to be calculated by the user.\r\n\r\nGDGT data can be used as paleothermometry and paleoenvironmental proxies, and we use the data to reconstruct the Holocene temperature evolution and local environmental conditions on Sumatra over the Holocene.\r\n\r\nThe data was generated by high performance liquid chromatography and mass spectrometry (HPLC-MS) measurements of polar lipid extracts. The soils are from an altitudinal transect 0\u2060\u200a\u2013\u200a\u20602840 m elevation range, while lake and peat core sediments are of ages up to 11000 years, i.e., almost the entire Holocene.\r\n","url":"http:\/\/bolin.su.se\/data\/hallberg-2022-sumatra-1","keywords":["Terrestrial","Geochemistry","brGDGTs","isoGDGTs","GDGT","H-GDGTs","Temperature reconstruction","Holocene","Proxy","Biomarkers","Lipids","Earth science > Atmosphere > Atmospheric temperature > Atmospheric temperature indices"],"creator":{"@type":"Person","name":"Petter H\u00e4llberg, Guillermo Jarne Bueno, Yolanda Schankat, Julia Steinbach, Hamdi Rifai, Caroline Bouvet de la Maisonneuve, Rienk H.
