(a) Dissolved phosphate (μmol/L) near surface
(b) Dissolved phosphate (μmol/L) at 20 m depth
(c) Chl- (mg/m3) near surface
(d) Chl- (mg/m3) at 20 m depth
Figure 4: Inshore-offshore near-surface (a and c) and 20 m depth (b and d) variability over time for dissolved phosphate (a and b) and Chl-a (c and d). Dissolved phosphate (μmol/L) and Chl-a (mg/m3) values are indicated as labels on respective isobars. The dissolved phosphate ranged between <0.5 μmol/L (grey) and >2 μmol/L (dark orange). Chl-a ranged between <4 mg/m3 (white) and >20 mg/m3 (dark green).
