Total phytoplankton biomass was determined from triplicate
50 mL samples collected at a depth of 0.5 m. The samples were
filtered (Whatman GF/F, 25 mm), extracted (90% acetone), and the
chlorophyll-a fluorescence was measured using a 10-AU fluorometer
(Turner Designs, Inc., Sunnyvale, CA; Strickland and Parsons,
1968). Total phytoplankton biomass was then estimated based on
the chlorophyll-a fluorescence values.
