Mapping Channel Currents: Vessel Data Reveals Complex Tidal Flows in Colombia

Tidal currents in port channels are rarely this telling. A study of Colombia's Tumaco, Buenaventura, and Málaga bays, built on 1.48 million vessel-mounted ADCP profiles, reveals that stratification alone cannot explain vertical shear asymmetry. Buenaventura and Málaga show ebb shear exceeding flood by 1.77 times, while Tumaco stays phase-independent. That contrast points to channel geometry and friction, not just water-column structure. It is a measured, peer-reviewed step toward understanding where single moorings fall short.
