Figure 4

(A) Abundance of bacteria (cell ml⁻¹) and associated standard deviation from duplicates. Black line represents 40 m samples; red, 60 m; blue, 110 m and green, 180 m. The estimated equivalent in carbon (µmol l⁻¹) is presented in (B) for 40 m, (C) for 60 m, (D) for 110 m and (E) for 180 m. The bold line represents estimates following cell biomass conversion factor⁴², the shaded area around the line represents for lower and upper values using lower and values for the cell biomass conversion factor as described in ref.⁴¹.
