Table 1.

Environmental data for T₁ to T₇ from 20 m and the surface (Surf) and subsurface chlorophyll maxima (SCM) at T₁ for Stn 101 and at T₂ for Stn 115; Temperature (T) in °C, salinity (S_P), dissolved oxygen (DO) in µM, relative fluorescence of colored dissolved organic matter (fCDOM), nitrite (NO₂), nitrate (NO₃), phosphate (PO₄) and silicate (Si) in µM. Ration of silicate to nitrite + nitrate (Si:N).
