3-3-3-3-3-3-3-3-3-3-3-3-3 From: Terry Plank <tplank@xxxxxxxxxxxxxxxxx> Seeking Ph.D. Candidate for Project: Sulfur Cycling at Subduction Zones Ph.D. candidate (Graduate Research Assistant) sought to work under the direction of Professor Terry Plank (Lamont Doherty Earth Observatory, Columbia University) to further our understanding of the sulfur cycle at subduction zones. Sulfur is a key element driving the climatic effects of arc volcanism, the economic potential of arc magmas, and the oxidation state of the Earth, and yet the inputs, processing, and recycling of S throughout the subduction system are still poorly constrained. The GRA will focus on making measurements of the sulfur contents and isotopic composition of marine sediments entering target subduction zones using XRF core scanning and mass spectrometry. This project is supported by an NSF/NERC-funded grant, â??Sulfur Cycling at Subduction Zonesâ??, with the principal aim of using sulfur isotopes as tracers of recycled sediment and arc volcano fluxes. This project involves close collaborations with the University of Oxford (led by Tamsin Mather) and the University of Palermo, Italy (led by Alessandro Aiuppa) and the Edinburgh Ion Microprobe Facility in the UK amongst others. Preferred candidates will have already completed a Masters degree or have carried out significant undergraduate research. Preferred qualifications include experience in the study of marine sediments and diagenetic reactions, stable isotopes, geochemical cycles, mass spectrometry and/or XRF core scanning. For further details please contact Terry Plank, tplank@xxxxxxxxxxxxxxxxx. US and International applicants welcome.
