A multi-disciplinary study of methane seepage at the Kazan mud volcano in the eastern Mediterranean Sea. Data was collected via the manned submersible Nautile, ship-based sediment coring, and geophysical surveys, integrating microbiology, biomarker, pore water, and solid phase geochemistry. Results indicate an anaerobic oxidation of methane rate of 6 mol m-2 year-1 and advective flow velocities of a few centimeters per year.
Use Cases
- Modeling methane flux and anaerobic oxidation rates based on pore water geochemistry data.
- Studying spatial heterogeneity in mud volcano environments based on integrated geophysical and biogeochemical surveys.
- Analyzing isotopic signatures in macrofaunal tissues and authigenic carbonates to trace methane-derived carbon.
- Investigating microbial community structure and function in relation to gas hydrate formation predicted at ~2m sediment depth.
Strengths
- Integrates diverse data types including microbiology, biomarkers, pore water, and solid phase geochemistry.
- Provides a quantified rate of anaerobic oxidation of methane (6 mol m-2 year-1) and advective flow velocities.
- Based on direct observations and sampling from the submersible Nautile and ship-based surveys.
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 study site at Kazan mud volcano.
