Ekman layer

n.
In a rotating fluid, a layer of relatively uniform fluid between a boundary (such as the surface) and the bulk of the fluid, especially the upper layer of the ocean whose currents are largely driven by the force of wind on the surface.

[After Vagn Walfrid Ekman (1874-1954), Swedish oceanographer.]

Fish eggs and larvae with near-surface distribution are more susceptible to the offshore transport in the Ekman layer associated with coastal upwelling (John & Re, 1995; Smith & Suthers, 1999; Rojas et al.
2001), during upwelling events the upper 20 m of the water column represent the Ekman layer, the 80-20 m stratum shows a reversal flow, and the 200-80 m stratum is a deep and more stable layer.
The Ekman layer velocity data have shown three types of systematic deviations from the situation described by the classical Ekman theory (Ekman 1905).
Attempts to observe the structure of the Ekman layer in the surface layers of the sea have been successful.
