The 18S T-RFs also differed between bloom and non-bloom
samples. T-RFs 302B and 212G were observed only in the nonbloom
samples (both total and >5 mm size fraction), and T-RFs 141G, 313B and 260B were observed only in the >5 mm size
fraction of the non-bloom samples, while in both size fractions TRFs
324B was only detected in the bloom (Fig. 5C and D).
