Web9 May 2024 · Organic matter burial in marine sediments comprises an integral component of the global carbon cycle and is of fundamental importance in regulating the balance of CO 2 and O 2 in the atmosphere on geological timescales ( Berner, 2001; Mills et al., 2024 ). Web8 Oct 2024 · Knowledge about organic carbon loadings (ratio of sedimentary organic carbon (SOC) content to specific surface area (SSA)) and the fate of organic carbon (OC) is critical to understand the marine carbon cycle. We investigated the variations in the patterns of OC loadings and the preservation capacities of sedimentary OC in the Yap Trench and … m.a. economics
