a Sampling location (yellow star) overlaid on MODIS-Aqua chlorophyll-A data averaged between March 1 and March 31, 2018, with dissolved iron profile at the sampling location. b Biological diversity of the proteins identified in the single-colony metaproteomes, with abundances of all detected proteins summed by major taxonomic groupings and separated by colony morphology. * Indicates significant difference from puffs without particles at p < 0.1, ** the same at p < 0.05, Welch’s unequal variance t-test. c–f Representative images of puff colonies with particles, g puff without particles, and h a tuft with some particles. Images were collected in epifluorescent mode using a DAPI long-pass filter set, without dyes. The scale bar in (c) applies to all images.
