This lecture explores the hidden circulation of the deep ocean and why the waters around Antarctica are so important to the global ocean system.
It examines how warm ocean currents and eddies interact with Antarctic ice shelves and sea ice, driving melting from below and releasing cold, fresh meltwater back into the ocean.
The lecture then looks at how this meltwater reshapes the surrounding ocean by changing water properties, currents, and the exchange between Antarctica and the open ocean.
Finally, it explores how changes around Antarctica can reach far beyond the polar regions, influencing the global transport of heat, carbon, and the deep overturning circulation.
Bishakhdatta Gayen is an ocean and fluid dynamics researcher who studies how the ocean influences the planet’s climate. He is an Associate Professor at the Indian Institute of Science (IISc), Bengaluru, and also holds an Associate Professor and Australian Research Council Future Fellow position at the University of Melbourne, Australia. His research spans geophysical fluid dynamics and physical oceanography, with a particular focus on deep-ocean circulation, Antarctic ice–ocean interactions, and the processes governing the transport of heat and mass through the oceans.
His research has been recognised across the world through several prestigious awards and fellowships, including the Andreas Acrivos Best Dissertation Award in Fluid Dynamics from the American Physical Society (APS), USA, an Australian Research Council (ARC) DECRA Fellowship, the R. J. L. Hawke Fellowship of the Australian Antarctic Division, an ARC Future Fellowship, and the John Booker Medal of the Australian Academy of Science. His work has appeared in leading journals including Nature Climate Change, Reviews of Geophysics, and the Annual Review series, PNAS, Phys Today.
