Relationship between (a) biogenic silica (%BSi as SiO2 per DW) and percentage carbon (%C) content and (b) biogenic silica and d13C in macroalgae samples collected from Narragansett Bay (RI, USA). Samples are color coded by phylum (Chlorophyta, green; Ochrophyta, brown; Rhodophyta, red). The shaded area around the regression line is the 95% confidence interval.
