Pore-water and solid-phase data from cold seep sediments in the Kazan Mud Volcano region of the Eastern Mediterranean Sea. The dataset likely contains depth-dependent methane concentrations, sulfate profiles, and isotopic compositions used to model anaerobic oxidation of methane (AOM) and gas hydrate formation. It was published by the Australian Ocean Data Network and last updated on 2026-06-16.
Use Cases
- Modeling methane fluxes and anaerobic oxidation rates based on pore-water sulfate and methane concentration profiles.
- Estimating gas hydrate formation potential based on modeled asymptotic methane concentrations and saturation values.
- Analyzing microbial biomass contribution to organic carbon pools using carbon isotopic mass balance data.
- Studying the impact of fluid advection on methane transport and transformation in marine sediments.
Strengths
- The description specifies a modeled, narrow depth interval of anaerobic oxidation of methane (AOM) between 14-18 cm below the sediment-water interface.
- The model results indicate microbial biomass from AOM represents about 20% of the total organic carbon, a quantified significant pool.
- The dataset is associated with a specific geographic feature, the Kazan Mud Volcano in the Eastern Mediterranean Sea.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Freshness should be verified as the last update date is in the future (2026-06-16).
