A global survey of long-term organic carbon decomposition in marine sediments: constraints to methanogenesis, gas hydrate formation, and C cycle budget

为旨在改进海洋沉积物中颗粒有机碳长期分解的量化的项目提供了资金。PI将对DSDP、ODP和IODP收集的POC数据进行全球调查，以测试将沉积物年龄和温度与POC分解率相关联的模型，这些模型将分别针对不同环境进行平均。结果将提供海洋甲烷生成和碳循环预算的限制。这项研究希望能够促进对长期有机碳循环的理解，这在气候变化中起着重要作用。两名本科生将参与这项研究，其中一名将从海洋领导计划联盟招募，该计划针对代表性不足的少数民族。

Funds are provided for the project that aims to improve quantification of long-term particulate organic carbon (POC) decomposition in marine sediments. The PI will conduct a global survey of POC data collected by DSDP, ODP, and IODP to test models relating sediment age and temperature to POC decomposition rates, which will be averaged separately for different environments. Results will provide constraints on marine methanogenesis and the carbon cycle budget. The study hopes to advance understanding of the long-term organic carbon cycle, which plays a role in climate change. Two undergraduate students will be involved in the research, one of which will be recruited from a Consortium for Ocean Leadership program that targets underrepresented minorities.
