Summary of the average percentage of colonial Crocosphaera watsonii-like cells (± standard error) in a given colony with higher 15N, 13C, or both 15N and 13C enrichment than the mean for the colony. The mean number of cells per colony is also provided.

jpy12057-sup-0003-FigS2.tifimage/tif11221KFigure S2. NanoSIMS imaging of colonial Crocosphaera watsonii-like cells shows evidence for diazocytes. (a-b) the 13C/12C and the 15N/14N of a colony from 12.3 h of incubation. (c-d) the 13C/12C and the 15N/14N of a colony from 18.3 h of incubation. Note in the 15N/14N images small localized areas of high enrichment similar in size expected of storage granules. Scale bar is 5 μm.
