From: Magnitude of nitrate turbulent diffusion in contrasting marine environments

Partial effects and residuals of nitrate diffusive flux as a function of predictors. The response variable was computed as a smooth function of sea surface temperature (SST), vertical nitrate gradient (grNO3) and surface chlorophyll-a (sCHL-a) for tropical and subtropical regions (T), the Northwest Mediterranean (M), the Galician coastal upwelling (G), the Antarctic Peninsula (A), and for the complete dataset except those stations collected in the Antarctic Peninsula (GM). All terms were centered in zero. Relationships where p-value < 0.05 are indicated as solid black lines, whereas no significant relationships are indicated as empty pannels. Intercepts and parameters are indicated in Table 3.
