Variosens fluorometer

Figure 2. The Variosens fluorometer calibration curve consisting of chlorophyll a concentration vs. the sample/hold output voltage. The general equation for an exponential function was chosen to describe the data, and the coefficients were obtained from a multiparameter fit that minimized (5).

Figure 3. Chlorophyll transect obtained from a constant depth tow at 11 m. Key a, raw Variosens data b, the same data filtered with a binomial smootning function having the best-fit value of a = 3,4 s and c, data from the Turner 111 fluorometer where samples are transmitted continuously (5).
