(meteorology)
The layer of transition between the surface boundary layer of the atmosphere, where the shearing stress is constant, and the free atmosphere, which is treated as an ideal fluid in approximate geostrophic equilibrium. Also known as spiral layer.

In both cruises the highest larval densities were found in non-upwelling waters (middle/deep strata) below the Ekman layer (>20 m), habitat continually affected by short-term variations as well oceanographic conditions changes due to circulation in the area (Marin et al.
In this study the vertical distribution of fish larvae during coastal upwelling in September 1998 and January 1999 off Punta Angamos showed changes during day/night suggesting diel vertical migration as a strategy to avoidance of the offshore Ekman layer during upwelling events; this migratory behavior would be independent of the condition type (upwelling/nonupwelling) as well as from hydrographic conditions registered at both oceanographic surveys.
