Professor Jemma Wadham, PhD, Professor of Glaciology at the Bristol Glaciology Centre at the University of Bristol talks about her goals of determining the role of glaciers and ice sheets in regulating global biogeochemical cycles, including evaluating the impacts of nutrients/carbon exported from ice sheets upon marine productivity and the impact of methane emission from subglacial and permafrost wetlands upon the atmosphere. Along with understanding water flow through cryospheric systems and the associated feedbacks with ice dynamics and glacial ecosystems. Futhermore, she is involved with the development and validation of in situ sensing technologies and autonomous platforms for the survey of icy ecosystems, including subglacial lakes and ice stream beds. Her lab uses Thermo Scientific IC tools to accomplish these goals.
