Hi, I start this episode by satisfying my curiosity on Life of an oceanographer as a Biogeochemist. Hannah Whitby gives us great insights into the reasons why Oceans play a major role in affecting our lifestyles and climate change Listen to her as she explains how Sea level changes actually affect half of human populations as they live within about 100 kms of our oceans. Oceans give us half the oxygen we breathe. Tiny little algae work very hard to stabilise the carbon footprint.
