 Abstract

Organic carbon OC in marine sediments is a critical component of the global carbon cycle, and its degradation influences a wide range of phenomena, including the magnitude of carbon sequestration over geologic timescales, the recycling of inorganic carbon and nutrients, the dissolution and precipitation of carbonates, the production of methane and the nature of the seafloor biosphere. Although much has been learned about the factors that promote and hinder rates of organic carbon degradation in natural systems, the controls on the distribution of organic carbon in modern and ancient sediments are still not fully understood. The result shows that higher OC content (>1.2 to 4.4%) is present in the top 2 m and lower content (<1 to 0.3 %) is present in the rest of the core with minor fluctuation. The low OC content in the early Holocene sediments may be due to the low productivity. High OC content during the late Holocene was due to the higher productivity in the study area.
