Dr Cara Manning

Earth Observation Scientist

Contact Details


Dr Cara Manning's research focuses on using biogeochemical tracers to study the ocean carbon and nitrogen cycles. As an Earth Observation Scientist at PML since 2020, she is using biogeochemical Argo data to characterize controls on the biological carbon pump.
Prior to her position at PML, Dr Manning was an NSERC Postdoctoral Research and Teaching Fellow at the University of British Columbia where she conducted research on the biogeochemical cycling of greenhouse gases in the North American Arctic Ocean and groundwater in British Columbia, and taught Field Techniques in Groundwater Hydrology. She earned her PhD in Chemical Oceanography from the Massachusetts Institute of Technology-Woods Hole Oceanographic Institution Joint Program in Oceanography. Her doctoral research included developing a new, portable method for measuring noble gases in seawater, and using new measurements of oxygen and noble gases to characterize rates of biological productivity and gas exchange in coastal waters. Dr Manning obtained her BSc (Hons) in Chemistry and Earth and Ocean Sciences from the University of Victoria, where she conducted research on nitrogen cycling in suboxic coastal systems.
