The Department of Earth Sciences at Dalhousie University in Halifax, Canada is seeking creative, self-motivated candidates for a fully funded Ph.D. position, focusing on compound specific isotope analysis of amino acids in organic paleoceanographic archives. This position leverages significant investments in ocean science at Dalhousie through the recently established Ocean Frontier Institute, internationally recognized expertise in biogeochemistry, brand new state-of-the-art laboratory dedicated to compound specific isotope analysis of amino acids, as well as ship time on the Canadian research icebreaker CCGS Amundsen in summer 2018.

Working under the supervision of Dr. Owen Sherwood and in collaboration with members of the Oceanography and Biology departments, the student will develop and apply novel biogeochemical proxies for nutrient-plankton dynamics in the Arctic and subarctic oceans. Using records preserved in deep-sea corals and sediments, the overarching goal will be to reconstruct changes in plankton productivity in relation to sea ice extent during the Holocene. For examples of the analytical approach please see recent articles by Sherwood et al. (2014) and McMahon et al. (2015). Experience with Gas Chromatography and/or Isotope Ratio Mass Spectrometry and strong analytical and writing skills will be considered assets. Prospective candidates should have completed a Masters degree or equivalent with a minimum “A minus” average. To apply, please send a cover letter, curriculum vitae and academic transcripts to: Dr. Owen Sherwood, Department of Earth Sciences, Dalhousie University, Halifax, Nova Scotia, B3H 4R2, Canada. E-mail: owen.sherwood@dal.ca, subject line: PhD search. Application deadline: March 15, 2018.
