Mangrove Sediment Nitrogen and Carbon Cycling Under Salinity Stress

Microcosm experiments using mangrove sediments under a salinity gradient of 0-30 psu quantify nitrogen transformation rates and carbon dynamics. The dataset includes measurements from geochemical analysis, functional gene quantification, and 15N isotope tracing to assess microbial processes like denitrification, anammox, and DNRA. It demonstrates how freshening from 30 to 10 psu reduces nitrogen removal efficiency by approximately 20% and impacts carbon preservation.

Use Cases

• Modeling nitrogen removal efficiency based on salinity and nitrate concentration data.
• Analyzing the stoichiometric shift in TA:DIC ratios to assess coastal acidification potential.
• Investigating sulfur-mediated regulation of nitrogen partitioning under different nitrate conditions.
• Correlating functional gene quantification data with measured rates of denitrification, anammox, and DNRA.
• Assessing the impact of ionic stress on carbon decomposition rates in wetland sediments.

Strengths

• Dataset size is 24469 units, suggesting a substantial volume of measurements.
• Employs a controlled microcosm experiment with a defined salinity gradient (0-30 psu).
• Integrates multiple analytical methods: 15N isotope tracing, geochemistry, and functional gene quantification.

Limitations

• Column names and a precise row count are not provided, limiting understanding of data structure.
• The dataset appears to be supplementary to a manuscript, which may limit standalone interpretability.
• The 'Last updated' date of 2026-03 23 is a future date, indicating a potential metadata error.
