Example of the remotely sensed distribution of total primary production P_{tot} for the whole Baltic (from Darecki et al. 2008) |
Quantum yield of photosynthesis Φ in the Baltic at different stations and at various depths in the sea: comparison of measured Φ and calculated _{M}Φ according to the model of the yield (from Woźniak et al.. 2007; eq. 4 and Table 1) (a); histogram of the ratio _{C}Φ (b)_{C}/Φ_{M} |

**Example maps of remotely sensed distributions in the Baltic Sea at 11:00 UTC on 24 April 2011:**

**(a) the depth of the euphotic zone z_{e}; (b) the photosynthetic index ε_{tot}; (c) the maximum quantum yield of carbon ﬁxation Φ_{max}; (d) the phytoplankton assimilation number P^{B} (e) the non-photosynthetic pigment factor f_{a}**

**Comparison of the statistical relationships between the relative concentrations of photoprotective carotenoids C _{PPC tot}/C_{chl a tot} and the optical depth τ (dots – experimental data, line – approximation of equation (5 in the paper) obtained for Baltic waters (a) (the results obtained in this study) and ocean waters (d) (Majchrowski 2001); comparison of empirical data C_{PPC tot, measured }and C_{PPC tot, calculated} approximated with the relevant equation (b, e); histograms of the ratios C_{PPC tot, meas}/C_{PPC tot, calc} for Baltic and ocean data respectively (c, f) (from Stoń-Egiert et al., 2012, OCEANOLOGIA, 54 (1), pp. 7–27, Fig. 5; see more in the paper).**
