Abstract:
We reconstructed temperature, hydroclimate, and vegetation from biomarkers in the 1-Myr continuous lake sediment record from Lake Towuti in Indonesia. Lake Towuti is located on the island of Sulawesi in the center of the Maritime Continent and Indo-Pacific Warm Pool. The cores were recovered in 2015 by the Lake Towuti Drilling project. All of the records span the past 1 Myr with ~3-kyr resolution. We produced these 1-Myr orbitally-resolved records of terrestrial temperature, rainfall, and vegetation in the Maritime Continent to elucidate how this critical region's climate interacted with major climate transitions during the past 1 Myr. We measured branched glycerol dialkyl glycerol tetraethers (br-GDGTs) to reconstruct temperature, leaf wax hydrogen isotopes to reconstruct hydroclimate, and leaf wax carbon isotopes. This data collection also includes the age model for the 1-Myr record and the chain lengths of all n-alkanes measured in the core.
