Organic Carbon Burial and Diagenesis - How Much Organic Carbon Is Actually Preserved?

Explore the fascinating process of organic carbon burial and diagenesis in marine environments through this informative 27-minute video. Discover the three major types of marine sediment and learn about the journey of organic matter from production to preservation. Understand the various factors that degrade organic carbon in the water column, at the seafloor, and beneath it. Delve into the concept of sediment diagenesis, including pore water-sediment reactions and post-depositional mineral transformations. Gain insights into the surprisingly small fraction of organic carbon that ultimately gets preserved and the resulting sediment zones. Perfect for earth science enthusiasts and students looking to deepen their understanding of marine geochemistry and microbiology.
