Pore-water and solid-phase data from the Kazan Mud Volcano constrain methane fluxes and anaerobic oxidation rates in cold seep sediments. Model results indicate a narrow 14-18 cm depth interval for methane oxidation and suggest microbial biomass accounts for about 20% of total organic carbon. The dataset was published by the Australian Ocean Data Network and last updated in April 2026.
Use Cases
- Model methane flux and anaerobic oxidation rates based on pore-water sulfate profiles
- Estimate microbial biomass contribution to organic carbon based on isotopic mass balance
- Predict gas hydrate formation rates based on asymptotic methane concentration data
- Quantify methane transformation in advective sediments using the proposed model approach
Strengths
- Data includes depth-dependent methane concentrations and pore-water sulfate profiles
- Model results specify a narrow 14-18 cm depth interval for anaerobic oxidation of methane
- Isotopic mass balance suggests microbial biomass represents about 20% of total organic carbon
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 (2026-04-16)
