Relation between Upwelling Intensity and the Variability of Physical and Chemical Parameters in the Southern Benguela Upwelling System

Table 2

Linear regression coefficients (slopes) for physical and chemical variables as a function of the upwelling index at the surface (3 to 5 m) and at 20 m sampling depths, for stations 1 to 12. Bold values indicate slopes that are significant at < 0.01.
