Two methods of determining the chlorophyll a concentration in the sea have been
formulated on the basis of artificially induced fluorescence measured with the aid
of submersible fluorometers. The method of statistical correlation is founded on
the empirical relationship between fluorescence and chlorophyll concentration. The
theoretical model of fluorescence described in Part 1 of this paper (see Ostrowska
et al. 2000, this volume) provides the basis of the other method, the physical
method. This describes the dependence of the specific fluorescence of phytoplankton
on the chlorophyll concentration, a diversity of photophysiological properties of
phytoplankton and the optical characteristics of the fluorometer. In order to assess their practicability, the methods were subjected to empirical
verification. This showed that the physical method yielded chlorophyll concentrations
of far greater accuracy. The respective error factors of the estimated
chlorophyll concentration were x = 2.07 for the correlation method and x = 1.5
for the physical method. This means that the statistical logarithmic error varies
from −52 to +107% in the case of the former method but only from −33 to +51%
in the case of the latter. Thus, modifying the methodology has much improved the
accuracy of chlorophyll determinations.
