Methods & Sampling

Methodology:

Duplicate cultures of Synechococcus WH8102 (axenic), Synechococcus WH7805 (xenic) and Prochlorococcus marinus MED4 (xenic and axenic) were sampled every other day for 17-19 days for the quantification of single cells, suspended aggregates (aggregates ca. 5-60 μm), and TEP. TEP concentrations were determined as in Passow and Alldredge (1995). The stock of Alcian-Blue dye used for TEP quantification had a calibration factor (f-factor) of 415.
