Methane Flux and Geochemistry Data from Kazan Mud Volcano, Eastern Mediterranean

Eastern Mediterranean Sea cold seep sediments from the Kazan Mud Volcano contain pore-water and solid-phase data for modeling methane fluxes and anaerobic oxidation. The dataset includes depth-dependent methane concentrations, sulfate profiles, and isotopic compositions, used to constrain microbial activity and gas hydrate formation. It was published by the Australian Ocean Data Network and last updated in April 2026.

Use Cases

• Modeling methane flux and anaerobic oxidation rates based on pore-water sulfate and methane profiles
• Estimating microbial biomass contribution to organic carbon based on isotopic mass balance calculations
• Predicting shallow gas hydrate formation rates based on asymptotic methane concentration data
• Analyzing fluid advection transport mechanisms based on conservative pore-water constituents like sodium and boron

Strengths

• Data supports a modeled, narrow depth interval (14-18 cm) for anaerobic oxidation of methane
• Includes isotopic compositions and biomarker distributions indicative of near-complete methane oxidation
• Model approach is described for predicting gas hydrate formation in surface sediments with fluid advection

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Description metadata is limited; actual data quality requires manual inspection after download
