Free Online Event

Join us for this free online event with Dr Russell Arnott, who will dive into the captivating world of why the Antarctic and Arctic Ocean currents play pivotal roles in regulating planetary climate systems, impacting global ocean currents and supporting marine biodiversity.
He will explain how processes in the polar regions drive global ocean circulation, such as ‘brine rejection’ during sea ice formation, which creates cold, salty, dense water that initiates the global ‘oceanic conveyor belt’.
Dr Russell Arnott holds a combined master's degree in oceanography from the University of Southampton, UK, and a PhD in marine biology from the University of Bath, UK, where he studied phytoplankton morphology and its influence on turbulent interactions.
He has worked as a commercial oceanographer, and his research has taken him all over the world, from the Southern Ocean with the British Antarctic Survey up to the Gulf of Bothnia in northern Sweden. Having worked as a science consultant on a number of books, Russell recently co-wrote his first book, Ocean Endangered, with researcher Celine Van Weelden.
Russell works with the charity Incredible Oceans, appearing on TV and radio, and speaking at science events around the world. He is currently a Teaching Fellow in Oceanography at University of Exeter’s Centre for Geography and Environmental Science and an Associate Lecturer in Ocean Science and Conservation at Falmouth University.
Russell’s talk will last about 40 minutes, after which he will be taking audience questions.
