Pore Water Geochemistry of Eastern Mediterranean Mud Volcanoes: Fluid Transport and Origin

Pore water chemistry from mud volcanoes in the Olimpi and Anaximander Mountains areas reveals moderate upward fluid advection velocities of 3-50 cm per year. The dataset, hosted by the Australian Ocean Data Network, was last updated in June 2026. It includes calculated formation water temperatures ranging from 55 to 145 °C, used to infer fluid origin depths and geochemical subsurface reactions.

Use Cases

• Modeling fluid advection and bioirrigation rates based on measured pore water profiles.
• Mapping spatial heterogeneity in fluid chemistry to infer discrete subsurface conduits.
• Predicting depth of fluid origin using theoretical geothermometers on calculated formation temperatures.
• Investigating the role of clay mineral dehydration in pore water freshening observed in surface sediments.

Strengths

• Includes quantified advective flow velocities (3-50 cm y⁻¹) and bioirrigation rates.
• Provides calculated formation water temperatures for two distinct geographic areas (55-80°C for Olimpi, 80-145°C for Anaximander).
• Data profiles were successfully simulated by accounting for upward advection and bioirrigation.

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 specific study areas in the eastern Mediterranean.
