Prof. Stephanie Henson is a Principal Scientist at the National Oceanography Centre and Honorary Professor at the University of Southampton, where she leads a large, active research group in global biogeochemical oceanography. Her particular research interests aim at understanding the natural variability and climate change effects on phytoplankton populations, and subsequent impacts on the biological carbon pump. Her research exploits autonomous vehicles, satellite and in situ data, as well as output from biogeochemical models. In 2012, she received the EGU Award for Outstanding Young Scientist for her ‘fundamental contribution to the study of marine ecosystems’, in 2016 she was awarded a highly competitive European Research Council Consolidator Grant, in 2018 she became the Challenger Society Fellow for Biological Oceanography, and in 2024 she received the EGU Fridtjof Nansen Medal for ‘distinguished research in oceanography’.  She was a lead author on the Intergovernmental Panel on Climate Change’s 6th Assessment Report, on the chapter “Carbon and other biogeochemical cycles and feedbacks”.
