Australian Ocean Data Network provides pore-water and solid-phase data from cold seep sediments in the Eastern Mediterranean Sea. The dataset likely contains depth-dependent methane concentrations, sulfate profiles, and biomarker distributions used to model anaerobic oxidation of methane (AOM) and gas hydrate formation. It was last updated on 2026-05-05.
Use Cases
- Modeling methane fluxes and oxidation rates based on pore-water sulfate profiles.
- Estimating gas hydrate formation potential based on asymptotic methane concentration data.
- Analyzing microbial biomass contributions based on carbon isotopic compositions of organic matter.
- Studying the impact of fluid advection on methane transport based on conservative pore-water constituents (Na, B).
Strengths
- Data includes depth-dependent methane concentrations and sulfate profiles for modeling.
- Model results indicate a narrow depth interval of AOM at 14-18 cm below the sediment-water interface.
- The biomass of the microbial population carrying out AOM represents about 20% of the total organic carbon.
- The predicted asymptotic methane concentration is close to the in situ saturation value with respect to gas hydrate.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect geographic bias inherent to the single-site study at Kazan Mud Volcano.
