Discussion

Study investigates sediment carbon and nitrogen distribution in coastal wetlands, suggesting how environmental factors regulate these elements.

Microbial biomass carbon and nitrogen decrease significantly with depth, with MBC dropping 45% and MBN by 50%.
Total carbon peaks at 6.49 g/kg in the 40-60 cm layer, while total nitrogen declines from 0.51 to 0.24 g/kg at depth.
Environmental factors such as tidal scouring and chemical stressors significantly influence sediment characteristics.
Understanding these dynamics aids in assessing carbon storage and managing coastal wetland ecosystems effectively.

Zhang et al. (2025) studied this question.
