Microscopic examination of white floc 2 (panels A through D) and orange floc (panels E through H). Paired phase contrast (A) and epiflourescent (B) images of DAPI-stained cells in white flocculent material from the Subway snowblower vent. SEM images of white floc show large clumps (C) and filaments (D) of microbial cells. Paired phase contrast (E) and epiflourescent (F) images of DAPI-stained cells in orange flocculent material from the seafloor surrounding Marker 33. SEM images of orange floc showing eukaryotic debris and hollow sheaths (G and H).
