Climate control on terrestrial biospheric carbon turnover

Timothy Eglinton et al.

Summary: Terrestrial vegetation and soils hold significantly more carbon than the atmosphere. Human activities impacting these reserves may exacerbate climate change uncertainties, particularly in extrapolating point-source observations to ecosystem-scale budgets. The turnover of organic carbon in river basins is influenced by mean annual temperature and precipitation, with implications for soil organic carbon vulnerability on a global scale. The scaling of riverine biospheric-carbon ages with soil OC turnover reveals the potential for constraints on carbon dynamics across broad spatial scales.

Controls on Organic Carbon Burial in the Eastern China Marginal Seas: A Regional Synthesis

B. Zhao et al.

Summary: The study revealed that there is selective decay of younger, more labile OC from both marine and terrestrial sources in the suspended particulate matter of the Changjiang River, while there is less decay of terrestrial OC along the Yellow River sediment dispersal pathway. The burial efficiency of OC in the mud areas of the Bohai Sea is significantly higher than in the Yellow and East China Seas, due to rapid deposition. The burial flux of biospheric OC in the Eastern China Marginal Seas was estimated to be 7.00 +/- 0.79 Mt yr(-1), with river damming significantly reducing OC burial and impacting the coastal ocean carbon budget.

Coal fly ash is a major carbon flux in the Chang Jiang (Yangtze River) basin

Gen K. Li et al.

Summary: The research found that the fossilized particulate organic carbon (FOCash) in fly ash, a byproduct of coal burning, has a significant flux in rivers like the Chang Jiang in China. This highly recalcitrant FOCash is difficult to oxidize, unlike the more labile FOCrock derived from shale. The high FOCash flux in the Chang Jiang was attributed to increased coal combustion and construction of dams, leading to a substantial impact of anthropogenic activities on the global riverine FOC flux to the oceans.

Degradation and Aging of Terrestrial Organic Carbon within Estuaries: Biogeochemical and Environmental Implications

Pengfei Hou et al.

Summary: Estuaries are crucial for organic carbon degradation and aging, which impact the export and burial of terrestrial organic carbon in marginal seas. This study found that fatty acid C-14 ages increased along the Pearl River estuary, indicating selective degradation of labile and younger organic carbon leading to apparent aging.

Contrasting fates of terrestrial organic carbon pools in marginal sea sediments

Meng Yu et al.

Summary: The burial of terrestrial organic carbon in marginal sea sediments plays a crucial role in the carbon cycle and has long-term impacts on atmospheric CO2 and climate. This study assessed the burial efficiency and fate of terrestrial organic carbon in the Bohai Sea and Yellow Sea, revealing spatial variability and highlighting the importance of organic matter age and composition in determining the fate of OCterr in marine sedimentary environments. The results suggest that OCterr in the mixed layer of sediments in this shallow marginal sea system is predominantly composed of millennial-aged organic carbon, with varying burial potential among different pools of OCterr.
