Marine Biogeochemistry Podcast

Lennart T. Bach

Marine biogeochemistry studies how elements like carbon and phosphorus move through the ocean. In this podcast, we explore the processes that drive this cycling. I’m Lennart Bach from the Institute for Marine and Antarctic Studies at the University of Tasmania, and I invite marine biogeochemists to discuss different elements and the roles they play, from well-known to less studied. Each episode focuses on one element and a specific topic, aimed at researchers and students.

When CO2 enters the ocean it has to cross the air-sea interface. This is surprisingly slow! And, thankfully reasonably well understood due to scientists like Prof. David Ho. In this episode, I talk with David about the flux of CO2 between the atmosphere and the ocean. David assumed this would be a podcast about marine CO2 removal, which is why he uses its abbreviation "marine CDR" occasionally (sorry for the insufficient briefing David!) I had a minor sound carfuffle at the beginning and I had to cut a small part of the intro. We therefore start quite abruptly.
