Calibration of forward scatter measurements. Relationship between forward scatter normalized to 1-μm calibration beads measured by SeaFlow and (a) diameter of calibration beads, (b) equivalent spherical diameter of phytoplankton cultures and (c) carbon quotas estimated with independent methods. Diameters of calibration beads were provided by the manufacturer while diameters of phytoplankton type were from electronic particle counter measurements; carbon quotas was determined by bulk measurements of particulate carbon normalized by cell number. Red lines represent Mie-based predictions using a refractive index of 1.60 (a) or 1.38 (b,c) and 1.35 and 1.41 for grey lines, relative to the refractive index of seawater (1.34).
