Carbon-14 Modelling of Cold Seep Carbonate Crusts

Australian Ocean Data Network hosts a dataset from a scientific journal paper investigating hydrological controls on cold seep carbonate crusts. It uses numerical modelling of carbon-14 (D14C) concentrations to study fluid convection processes in the eastern Mediterranean Sea. The dataset was last updated in April 2026.

Use Cases

• Simulate crust D14C levels based on fluid CH4, Ca2+, and HCO3 concentrations using the provided numerical model.
• Constrain chemical and hydrological conditions of crust formation by reproducing the 14C content of eastern Mediterranean Sea samples.
• Assess the impact of convection versus advection, bioirrigation, eddy diffusion, and bioturbation on crust D14C signatures.
• Investigate the influence of host sediment carbon age (old or modern carbon) and crust formation time on final D14C values.

Strengths

• Data is derived from a peer-reviewed scientific journal paper, ensuring methodological rigor.
• Numerical model allows for controlled investigation of multiple chemical and hydrological variables.

Limitations

• Specific dataset size, row count, and column details are unknown.
• Geographic scope is limited to cold seeps in the eastern Mediterranean Sea.
