Professor Mike 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 globalclimate, the ice sheets, and the interdisciplinary ocean system. He is an Honorary Professor at the University of Bristol, aFellow of the Royal Geographical Society, and a NERC Individual Merit Promotion (Band 2) scientist. He has publishedmore than 200 papers in international journals, and was the inaugural Chair of the Southern Ocean Observing System. Heled the design and delivery of the multi-institute ORCHESTRA programme, which is unravelling the role of the SouthernOcean in controlling global climate. He was recently coordinating lead author for the IPCC Special Report on Oceans andCryosphere in a Changing Climate. In 2018, Mike 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, forhis contributions to marine science. Professor Alberto Naveira Garabato is an oceanographer interested in the processes governing ocean circulation and its rolein climate. His group’s research focuses on unravelling the dynamics connecting the breadth of scales of oceanic flow—from small-scale turbulence to the basin-scale circulation—through the development and application of new approaches tomeasure the ocean. He holds a Chair of Physical Oceanography at the University of Southampton, and is an Honorary Fellowof the British Antarctic Survey. His work has been recognised with the Outstanding Early Career Scientist Award of theEuropean Geosciences Union (2008), an Honorary Fellowship of the Challenger Society (2010), a Philip Leverhulme Prize(2010) and a Royal Society Wolfson Research Merit award (2014). He was the lead proponent of the RoSES programme,which is assessing the role of the Southern Ocean in the global carbon cycle. He is the founding director of the NEXUSSCentre of Doctoral Training, which is training 45 PhD students at 10 UK institutions in the use of cutting-edge sensor andautonomous system technologies for environmental science.
