Methane Flux and Geochemistry Data from Kazan Mud Volcano

Carbon Geochemistry of Cold Seeps dataset contains pore-water and solid-phase measurements from sediments at the Kazan Mud Volcano in the Eastern Mediterranean Sea. The Australian Ocean Data Network published this research data, which models methane concentrations, anaerobic oxidation rates, and gas hydrate formation potential. The dataset was last updated in April 2026.

Use Cases

• Model methane flux and anaerobic oxidation of methane (AOM) rates using pore-water sulfate profiles and advective flow velocity estimates.
• Analyze carbon isotopic compositions of organic matter and dissolved inorganic carbon to trace methane-derived carbon pools.
• Predict gas hydrate formation zones by correlating asymptotic methane concentration data with in situ saturation values.
• Study biomarker depth distributions, such as those from 14-18 cm below the sediment-water interface, to validate near-complete anaerobic oxidation.

Strengths

• Data supports a detailed isotopic mass balance, quantifying that microbial biomass represents about 20% of total organic carbon.
• Modeling approach constrains processes to a narrow, specific depth interval of 14-18 cm below the sediment-water interface.

Limitations

• Dataset size, row count, and specific column details are unknown.
• Geographic scope is limited to a single location: the Kazan Mud Volcano in the Eastern Mediterranean Sea.
