摘要：
Organic matter preservation in marine sediments helps sequester CO2 from the atmosphere. This paper reviews this preservation process. Topics discussed include (1) molecularly uncharacterized organic matter, (2) organic matter preservation in marine sediments, (3) "mechanisms" of preservation, (4) preservation as a result of the inhibition of remineralization, (5) relationship between physical protection, oxygen exposure, and abiotic condensation reactions in sediment carbon preservation and (6) organic matter preservation in marine sediments and sediment organic carbon budgets.
