Pore-water and solid-phase geochemical data from the Kazan Mud Volcano in the Eastern Mediterranean Sea, published by the Australian Ocean Data Network. The dataset includes depth-dependent methane concentrations, sulfate profiles, and isotopic compositions used to model anaerobic oxidation of methane (AOM) and gas hydrate formation. The last update was recorded on 2026-06-27.
Use Cases
- Modeling methane flux and anaerobic oxidation rates based on pore-water sulfate and methane concentration profiles.
- Predicting gas hydrate formation in sediments based on modeled asymptotic methane concentrations and saturation values.
- Quantifying the microbial biomass contribution to organic carbon using isotopic mass balance calculations mentioned in the description.
- Analyzing the depth interval of anaerobic oxidation of methane (AOM) based on biomarker and isotopic data from sediment cores.
Strengths
- Includes depth-dependent pore-water data for key constituents like sulfate, methane, sodium, and boron.
- Contains isotopic compositions of organic matter and dissolved inorganic carbon for mass balance analysis.
- Model results indicate a narrow, defined AOM interval between 14-18 cm below the sediment-water interface.
- Data is associated with a specific, well-described location: 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.
- Data freshness should be verified despite the last update being 2026-06-27.
