Geoscience Australia Data provides a dataset on methane fluxes and transformation in cold seep sediments from the Kazan Mud Volcano in the Eastern Mediterranean Sea. The data includes pore-water and solid-phase measurements used to model anaerobic oxidation of methane (AOM) and gas hydrate formation. The dataset was last updated on 2026-03-25.
Use Cases
- Modeling methane flux and anaerobic oxidation rates based on pore-water sulfate and methane concentration profiles.
- Estimating microbial biomass contribution to organic carbon based on isotopic mass balance calculations.
- Predicting shallow gas hydrate formation rates based on modeled asymptotic methane concentrations.
- Quantifying fluid advection transport mechanisms in surface sediments using conservative pore-water constituents (Na, B).
Strengths
- Data is used to constrain a narrow depth interval (14-18 cm) for anaerobic oxidation of methane.
- Model results indicate microbial biomass from methane oxidation represents about 20% of total organic carbon.
- The proposed model approach is described for predicting gas hydrate formation and quantifying methane fluxes.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
