Biogeochemical and Ecological Data from Kazan Mud Volcano, Eastern Mediterranean

A multidisciplinary dataset integrates observations from the manned submersible Nautile, ship-based sediment coring, and geophysical surveys at the Kazan mud volcano. The data focuses on biogeochemical processes like anaerobic oxidation of methane (AOM) and associated microbial and macrofaunal communities. The dataset was published by Geoscience Australia Data and was last updated on 2026-04-30.

Use Cases

• Modeling methane oxidation rates based on reported AOM rate of 6 mol m-2 year-1 and advective flow velocities.
• Studying spatial heterogeneity in biogeochemical conditions based on integrated pore water and solid phase geochemistry.
• Analyzing community structure of seep-associated microbiota and macrofauna based on carbon isotopic measurements of organic matter and tissues.
• Investigating gas hydrate formation dynamics based on predicted occurrence at sediment depths of about 2 meters.

Strengths

• Integrates multiple data types including microbiology, biomarkers, pore water geochemistry, and geophysical surveys from a specific field site.
• Reports specific quantitative findings, such as an AOM rate of 6 mol m-2 year-1 and advective flow velocities on the order of centimeters per year.
• Data collection utilized advanced tools like the manned submersible Nautile for visually selected site sampling.

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.
