Chroococcoid cyanobacteria in the sea: A ubiquitous and diverse phototrophic biomass1
Open accessAbstract
In the photic zone of the open sea, procaryotic cells with an ultrastructure typical of chroococcoid cyanobacteria and similar sized populations of autofluorescent bacteria (0.5–1.0 × 1.0 µ m) were observed at concentrations usually between 10 3–10 4 cells per ml. The ubiquitous ultrastructural type was an orange‐autofluorescing, phycoerythrin‐containing cyanobacterium amenable to culture. Two other morphological types which have not been cultured occur sporadically in larger concentrations, one apparently favoring deeper water. These phototrophs can account for about 20% of the total bacterioplankton biomass and from 6 to 15% of the total microbial plankton. These cells may play a significant role in oceanic primary productivity.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
