Primary Supervisor – Prof. Jan Kaiser Scientific background: The 2015 Paris Agreement aims to avoid dangerous climate change by reducing emissions of carbon dioxide (CO 2 ) and other greenhouse gases. Independent top-down constraints on emissions require accurate measurements of CO 2 concentrations and fluxes, as well as verifiable attribution to natural and anthropogenic sources, using tools such as the isotopic fingerprint of CO 2. Recent technological developments now allow the analysis of ever rarer isotopic CO 2 species, called polyisotopologues, which offer novel insights into the origin and fate of atmospheric CO 2. This studentship builds on the ongoing UKRI NERC POLYGRAM project (POLYisotopologues of GReenhouse gases: Analysis and Modelling; https://polygram.ac.uk ). Research Methodology: You will work with existing data and generate new data to extend the geographic range of CO 2 polyisotopologue applications to key carbon cycle processes. Specifically, you will: analyse and interpret seasonal and interannual variability of triple oxygen ( 16 O, 17 O, 18 O) and stable carbon ( 12 C, 13 C) isotopes in CO 2 at Weybourne Atmospheric Observatory (WAO; north Norfolk) quantify oxygen isotope variations in CO 2 at Alice Holt Forest Research Station in Hampshire to investigate ecosystem-scale carbon cycle processes evaluate isotope gradients in CO 2 at remote locations around the globe and from shipboard latitudinal transects across the Atlantic Ocean, as a measure of global primary productivity variations Training: You will join a research team at UEA, but also work with our UK collaborators and visit the University of Groningen (Netherlands). You will develop proficiency in: CO 2 and H 2 O isotopologue measurements using laser spectrometers in field and in laboratory Advanced statistical analysis of time-series data, including modelling techniques Networking skills (e.g., via the National Centre for Atmospheric Science summer school) Presentation techniques and scientific writing (including conferences and peer-reviewed publications) Person specification: We seek an enthusiastic team player with strong scientific interests, self-motivation, and numerical skills. You will have a degree in environmental sciences, physics, chemistry, natural sciences, engineering or equivalent, and a strong interest in the carbon cycle and climate change.
