    Professor Michael Meredith is an oceanographer and Science Leader at the British Antarctic Survey (BAS) in Cambridge, UK. He is head of the Polar Oceans team at BAS, which has research foci on determining the role of the polar oceans on global climate, the ice sheets, and the interdisciplinary ocean system. He is an Honorary Professor at the University of Bristol, a Fellow of the Royal Geographical Society, and a NERC Individual Merit Promotion (Band 2) scientist. He has published more than 200 papers in international journals, and was the inaugural Chair of the Southern Ocean Observing System. He led the design and delivery of the multi-institute, £10M ORCHESTRA programme, which is unravelling the role of the Southern Ocean in controlling global climate. He was recently Coordinating Lead Author for the IPCC Special Report on Oceans and Cryosphere in a Changing Climate. In 2018, Michael was awarded the Tinker-Muse Prize for Science and Policy in Antarctica, in recognition of his contributions to the study of the Southern Ocean and its global impacts, and the Challenger Medal, for exceptional contributions to Marine Science. In 2020, he was awarded the Polar Medal. In 2022, Michael was elected President of the Challenger Society for Marine Science, the UK’s pre-eminent learned body for research of the ocean.


    More than 200 papers in international journals.
