Oceanic Dissolved Organic Carbon - The World Tour

Embark on a comprehensive exploration of oceanic dissolved organic carbon, one of Earth's major carbon reservoirs, in this 1-hour 20-minute AGU Reeburgh Lecture. Dive into the macro dynamics of this 660 PgC pool, examining its production, removal, and sequestration through observations of spatial and temporal variability across global oceans. Tour all ocean basins to investigate sources, sinks, and controls, while also addressing the challenges in understanding micro dynamics such as molecular composition and transformations. Cover key topics including upper ocean distribution, net community production, prokaryote abundance, and specific focuses on the Atlantic and Pacific oceans. Gain insights into the current state of knowledge and ongoing research efforts in this critical area of Earth science, concluding with a question and answer session to deepen understanding.
