Description

Total bacterioplankton ("bacteria"), including Archaea and Prochlorococcus, determined by flow cytometry from the POWOW1 (TN277) cruise.

Methods & Sampling

Bacterioplankton (i.e. ‘bacteria’) were enumerated using a FACSCalibur flow cytometer (Becton Dickinson) and populations characterized as previously described (Johnson et al., 2010). Briefly, cells were excited with a 488 nm laser (15 mW Ar) and inelastic forward (<15°) scatter, inelastic side (90°) scatter (SSC), green (530 ± 30 nm) fluorescence, orange fluorescence (585 ± 42 nm), and red fluorescence (> 670 nm) emissions were measured. Bacterioplankton were quantified by staining the samples with the nucleic acid stain SYBR Green –I (Molecular Probes Inc.) (Marie et al., 1997).

Data Processing Description

Cells counts were normalized to volume sampled to determined cells per mL.

BCO-DMO edits made:
- Parameter names have been changed to conform to BCO-DMO conventions.
- month_utc, day_utc, and year were added, based on the original date field.
- Original version of data (dated 22 March 2013) replaced with updated version 28 May 2013.

Instruments

Flow Cytometer

Supplied Description:

A FACSCalibur flow cytometer (Becton Dickinson) was used to enumerate bacteria.

Instrument Type

Generic Name: Flow Cytometer

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/LAB37/

Generic Description:

Flow cytometers (FC or FCM) are automated instruments that quantitate properties of single cells, one cell at a time. They can measure cell size, cell granularity, the amounts of cell components such as total DNA, newly synthesized DNA, gene expression as the amount messenger RNA for a particular gene, amounts of specific surface receptors, amounts of intracellular proteins, or transient signalling events in living cells.
