Alkenone UK'37 data of sediment samples from Deep Sea Drilling Project (DSDP) site 594 in the South Pacific

Alkenone abundances and resulting temperature reconstruction from sediment samples retrieved from DSDP Leg 90, Site 594, South Pacific. Sediments are dated from 3.4-3.0 Ma. The age of samples was determined using the age model of Caballaro-Gill et al. (2019) (https://doi.org/10.1029/2018PA003496). Alkenone abundances were solvent extracted and measured using gas chromatography-flame ionisation detection (GC-FID). The relative alkenone abundances were converted to sea surface temperature using the UK’37 index and the calibration of Müller et al (1998). All analyses were performed at The Open University, UK. Data was collected between 2023 and 2024 by Sarah Cottee, Bridget Warren, and Marcus Badger. Data analysis was supported by NERC grant NE/X000567/1, Marcus Badger.
