Abstract:
Temperature reconstruction from Lake Towuti, Indonesia that spans the past 1-Myr with ~3-kyr resolution. The temperature reconstruction is based on the fractional abundances of branched glycerol dialkyl glycerol tetraethers (br-GDGTs) measured in the cores. We analyzed the samples using atmospheric pressure chemical ionization/high-performance liquid chromatography mass spectrometry (APCI/HPLC-MS) with a bridged ethylsiloxane/silica hybrid (BEH) hydrophilic interaction chromatography (HILIC) 1.7 um (2.1 x 150 mm) column using selective ion monitoring mode, targeting molecules at m/z 1050, 1048, 1046, 1036, 1034, 1032, 1022, 1020, 1018, 1292, 1296, 1298, 1300, and 1302. We report the fractional abundances of the GDGTs measured in the core and the reconstructed temperature.
