Dataset: Microbial abundances from the Cariaco Basin

All samples were collected via Niskin bottles.

Total microbial biomass and flagellate abundance was determined by staining formaldehyde-preserved seawater with acridine orange and filtering onto black polycarbonate 0.2um or 0.8um filters, respectively, according to Hobbie et al. (1977) and Taylor et al. (2001). Cells were enumerated visually on a Zeiss Axioscope epifluorescent microscope with the appropriate filter set. Viral-like particles were stained with SYBRgreen, filtered onto 0.02µm black Anodisc filters and visually enumerated on the epifluorescent microscope with the appropriate filter set, according to Noble and Fuhrman (1998) and Taylor et al. (2001).
