Dr Ajit Subramaniam was recently on board a 100-metre research ship, on an epic 55-day expedition across the equatorial Atlantic, uncovering the secret life of phytoplankton and the future of ocean health. This in-depth interview explores the critical role of oceanography in understanding climate change and its impact on food security, marine ecosystems and more.
Dr Subramaniam is a Lamont Research Professor at the Lamont Doherty Earth Observatory of Columbia University. He is an oceanographer with expertise in biogeochemical cycles, remote sensing, bio-optics, and phytoplankton physiology. He is interested in advancing our ability to observe the ocean and expand our understanding of how marine ecosystems work.
In this interview, we dive deep into: • How phytoplankton regulate global CO2 and oxygen levels • The dangers of marine heatwaves, ocean acidification, and rising seas • Cutting-edge technologies like robotic floats, gliders, and AI-driven sensors • India’s role in monitoring monsoons via equatorial moorings • Breakthroughs in Marine Carbon Dioxide Removal (MCDR) as a nature-based climate solution
