Postdoctoral research position in paleo-ocean chemistry The faculty of Earth Sciences of the Vrije Universiteit, Amsterdam has a vacancy for a postdoctoral researcher in paleo-ocean chemistry in the Department of Petrology and Isotope Geology. The Department of Petrology and Isotope Geology takes part in the teaching programme of the faculty of Earth Sciences, carries out scientific research and participates in the Netherlands Research School of Sedimentary Geology. The faculty of Earth Sciences has at its disposal first-class facilities in analytical chemistry, especially in the field of isotope geology. Project outline The candidate will measure lithium isotope ratios in the skeletons of marine organisms over a range of ages. The study will tackle problems of fractionation and diagenetic alteration in trying to construct a robust history of lithium isotopic variation in the oceans. Requirements Potential candidates must hold a PhD and have experience in chemical paleo-oceanography. Familiarity with clean lab and mass-spectrometric procedures would be advantageous.
