Xennephone Hadeen

While at JCU I primarily worked as a Research Scientist/PhD student in Paleoclimatology with a strong focus in isotope geochemistry and biogeochemistry for my PhD project. My PhD was strictly research-based. The project resulted in a high-resolution reconstruction of 155,000 years in Northern Australia. Fieldwork was conducted at Girraween Lagoon, near Darwin, Northern Territory Australia. n-Alkanes (leaf waxes) from plants extracted from a 20 m sediment core were utilized for the project. Stable carbon isotopes were utilized to reconstruct the paleoenvironment (plant cover) over time while stable hydrogen isotopes were applied to reconstruct the past precipitation (climate) over time in the area. I conducted all the lab work myself for this project utilizing isotope geochemistry and biogeochemistry while following strict safety standards. Samples were measured on a GC-MS and an IRMS.
