Triple

Target class: mesoscale ocean feature
Context triple: [Great Whirl, instanceOf, mesoscale ocean feature]

• A. oceanographic front
  An oceanographic front is a boundary zone in the ocean where distinct water masses with different temperatures, salinities, or densities meet, creating sharp horizontal gradients and often enhanced biological and physical activity.
• B. ocean current chosen
  An ocean current is a continuous, directed movement of seawater driven by factors such as wind, Earth's rotation, temperature, and salinity differences, which redistributes heat, nutrients, and organisms across the world's oceans.
• C. oceanographic process
  An oceanographic process is a natural physical, chemical, or biological mechanism that drives changes and interactions within the ocean system over space and time.
• D. physical oceanographic system
  A physical oceanographic system is the interconnected set of oceanic processes, properties, and structures—such as currents, waves, temperature, and salinity—that govern the movement and distribution of energy and matter in the sea.
• E. deep water mass
  A deep water mass is a large, relatively homogeneous body of seawater formed at high latitudes that sinks and spreads through the deep ocean, characterized by distinct temperature, salinity, and chemical properties.
• F. None of above.
