Dr Stephen Dye
Deputy Chief Scientist
Stephen is Deputy Chief Scientist for Cefas and a Principal Physical Oceanographer and Marine Climate Change Scientist. He coordinates the activities of the Chief Scientist Office (CSO) and works across Cefas to enable the delivery of the Cefas Science, Evidence and Advice Strategy (SEAS).

Stephen has worked on our strategic science direction since 2018 initially as co-lead for Ecosystem Change & Variability and since 2021 enabling the strategic science work across Cefas as Science Lead and now as Deputy Chief Scientist. In this role he also coordinates the activity of the Chief Scientist’s Office and has responsibility for internal investment in innovative science as well as engagement with academia through doctoral training.
His science and advisory background is as a Principal Marine Physical Oceanographer & Climate Scientist. He has >25 years’ experience as a physical oceanographer examining the variability of marine physical processes on seasonal to decadal time-scales using moored instruments, hydrodynamic models and hydrographic data-sets. He works to understand the role of the ocean in the climate system and interactions between ocean and atmosphere so that we can predict how ocean basin-scale processes in the North Atlantic and sub-Arctic seas affect ecosystems in the UK’s shelf seas. He has played a leading role in assessing and communicating the effects of climate change in the marine environment through national and international collaborations such as the Marine Climate Change Impacts Partnership (MCCIP), OSPAR Quality Status Reports and the ICES Report on Ocean Climate.
Stephen is an Honorary Associate Professor at UEA where he is Deputy Director of the Cefas-UEA Collaborative Centre for Sustainable Use of the Seas, he is a Fellow of the Challenger Society for Marine Science (2006) and is Chair of the Editorial Board for the society’s publication Ocean Challenge. Since 2020 he has been Cefas’s representative on the Steering Group for the First Light Festival, a free science, music and arts festival on the beach in Lowestoft.
