NED1 Entity disambiguation (via context triple) gpt-5-mini-2025-08-07
Target entity: Ekman spiral
Context triple: [Ekman layer, hasPart, Ekman spiral]
  • A. Ekman layer
    The Ekman layer is the thin region of fluid near a boundary (such as the ocean surface or seafloor) where the balance between friction and the Coriolis effect causes the flow to spiral with depth.
  • B. Ekman transport
    Ekman transport is an oceanographic process in which wind-driven surface waters move at an angle to the wind direction due to the Coriolis effect, causing net water transport perpendicular to the wind.
  • C. Ekman
    Ekman is a Swedish surname borne by several notable figures in Sweden’s cultural and public life.
  • D. Langmuir circulation
    Langmuir circulation is a wind-driven pattern of shallow, counter-rotating vortices in the upper ocean that organizes floating material into parallel streaks on the water surface.
  • E. Taylor–Proudman theorem
    The Taylor–Proudman theorem is a fundamental result in geophysical fluid dynamics stating that in a rapidly rotating, inviscid, incompressible fluid, steady flows tend to be uniform along the axis of rotation, leading to columnar motion.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
