- FIG. 1.
Schematic diagram of the FluoroMAP fluorometer (A) and close-up of the fluorescence sensor and sample volume (B).
- FIG. 2.
FluoroMAP fluorescence intensities (•) (mean ± standard deviation; arbitrary units [a.u.]) and cell concentrations (□) (cells/μl) determined by flow cytometry during simulated blooms for cultures of P. lutheri (A1) and C. muelleri (B1). Representative cytograms show the fluorescence intensity (red fluorescence) and size (side scatter) of populations of P. lutheri (A2) and C. muelleri (B2).
- FIG. 3.
(A) High-resolution vertical profile of fluorescence intensity (arbitrary units [a.u.]) with depth in the Southern Ocean. (B) Enlarged section of the fluorescence microstructure shown in panel A between 23.7 and 24.7 m, showing a typical peak structure for a 1-m section.
- FIG. 4.
(A) High-resolution vertical profile of fluorescence intensity (arbitrary units [a.u.]) with depth in the eastern English Channel. (B) Enlarged section of the fluorescence microstructure shown in panel A between 6.5 and 7.5 m, showing a typical peak structure for a 1-m section.
- FIG. 5.
(A) Comparison of the FluoroMAP fluorescence intensity (arbitrary units [a.u.]) time series determined in situ at a depth of 17 m in Southern Ocean waters (gray) and in the laboratory for a solution of MilliQ water (black). (B) Close-up of the fluorescence intensity of the MilliQ signal in panel A between 20 and 30 s.
