| Summary: | * These data represent: Raw data presented in Sluijs et al., 2020 (Climate of the Past) - Peak areas of GDGTs and GMGTs peaks across the late Paleocene - early Eocene of Hole 4 of the Arctic Coring EXpecition (ACEX). - Abundances of isoGDGTs and and chrenarchaeol in the modern peat dataset. * where The data were generated on sediment samples taken from drill cores retreived from Lomonosov Ridge, Arctic Ocean, 2004 by the Integrated Ocean Drilling Program, stored in the Bremen Core Repository. For the present paper, we analyzed organic lipid extracts previously documented by Sluijs et al., (2006; 2008; 2009) using the current methodological standards. * when and how The lipid extracts were analyzed in 2018 in the organic geochemical laboratory at Utrecht University using Ultra High Performance liquid chromatography and atmospheric pressure chemical ionization mass spectrometry using an Agilent 1260 Infinity series HPLC system coupled to an Agilent 6130 single-quadrupole mass spectrometer (methods follow Hopmans et al., 2016) * why We re-analyzed the extracts because analytical methodology has improved since the generation of the original datasets and because the dataset from the Arctic is crucial for Paleocene-Eocene climatology. |
