Target class: physical oceanography concept
Context triple: [Ekman transport, instanceOf, physical oceanography concept]

• A. ocean current
  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.
• B. 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.
• C. ocean observing program
  An ocean observing program is a coordinated, long-term effort that systematically measures and monitors physical, chemical, biological, and geological properties of the ocean to support research, forecasting, and resource management.
• D. ocean
  The ocean is a vast, continuous body of saltwater that covers most of Earth's surface, regulating climate and supporting diverse marine ecosystems.
• 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. chosen
