Example of the remotely sensed distribution of total primary production Ptot 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 ΦM and calculated ΦC according to the model of the yield (from Woźniak et al.. 2007; eq. 4 and Table 1) (a); histogram of the ratio ΦCM (b)

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