PhytoFlash Active Fluorometer
The PhytoFlash
is a patented solid-state submersible active fluorometer
designed to detect minimum fluorescence (Fo), maximum
fluorescence (Fm), and quantum efficiency (Fv/Fm or
yield) of phytoplankton. These data can be determined
during extended deployments, CTD profiles, or in the
laboratory.
Performance Data:
Copper sulfate (CuSO4)
was used to inhibit photosynthesis in a green alga (Dunaliella)
culture to demonstrate how yield is affected by "impacted"
systems. Yield was evaluated using the PhytoFlash active
fluorometer. Measurements were taken at 1-minute intervals
over a 50-minute period for two sub-samples, a control
and an experimental sample. 100 mM CuSO4 was added to
the experimental sample at the 4-minute mark.
