Overview
This course explores the process of organic carbon burial and diagenesis, focusing on the preservation of organic carbon in marine sediments. By examining microbial zonation, types of marine sediments, production of organic matter, degradation processes in water and at different sediment layers, students will learn about sediment diagenesis and the factors affecting organic carbon preservation. The course also covers pore water-sediment reactions, subsurface microbial degradation, and resulting sediment zones. The intended audience includes individuals interested in geosciences, environmental sciences, or marine biology. The teaching method involves a video lecture format with detailed explanations and visuals to enhance understanding.
