Submarine Channel Morphology Measurements for Coriolis Force Analysis

A global dataset of submarine channel sinuosity and curvature measurements from nine modern systems, published in 2017. It contains measurements from hundreds of channel bends, used to reevaluate the relationship between latitude and channel sinuosity. The data and code were created by Zoltán Sylvester and accompany a SEPM Special Publication.

Use Cases

• Testing the influence of the Coriolis force on channel planform based on latitude and sinuosity data.
• Modeling the evolution of submarine channel centerlines based on curvature and sinuosity measurements.
• Analyzing the relationship between flow velocity and levee asymmetry in submarine channels.
• Comparing the geomorphic characteristics of submarine channels across different latitudinal zones.

Strengths

• Includes measurements from hundreds of channel bends across nine modern systems.
• Accompanied by openly available code for automated sinuosity and curvature calculation.
• Data supports a specific, peer-reviewed scientific publication (SEPM Special Publication 108).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
