At the present time we still do not have appropriate numerical Bioactive Compound Library cost data characterizing the accuracy of current and/or forecast estimates

of other structural and functional parameters of marine ecosystems, in particular the concentration of chlorophyll a, which would support the usefulness of such coupling. Even so, this usefulness is being confirmed by the preliminary results of analyses, the results of which will be published at a later date. The work done so far in the SatBałtyk project confirms the usefulness of satellite systems for the comprehensive and effective monitoring of the current state of the marine environment, and also to a large degree for the forecasting of a whole range of natural phenomena taking place in Baltic waters and in the atmosphere above, including the monitoring of the water’s purity and the extent of its eutrophication. These satellite systems enable the production of maps of spatial distributions of many state parameters of this environment, as well as certain state parameters and optical properties of the atmosphere, surface

temperatures in different basins and hence surface currents and upwelling events, the range and direct spread of river waters in the Baltic, water transparency and the optical properties of the sea, the depth of the euphotic zone, the radiation balance at the sea surface and in the upper layers of the atmosphere, the intensity of UV Protein tyrosine phosphatase radiation PFI-2 in vivo over the sea and coastal areas, the distributions of irradiance energy useful for photosynthesis PAR, the concentration of chlorophyll and other pigments in the water, the primary production of organic matter and the photosynthetically released oxygen in

the sea, as well as the extents of phytoplankton blooms (including toxic cyanobacteria). It is also possible to determine a range of biological parameters characterizing, among other things, the condition of marine life, in particular algae and their physiological and phytophysiological parameters like the maximum assimilation number, the factor of non-photosynthetic pigments, the efficiency of photosynthesis at different depths, and the maximum quantum yield of photosynthesis in water of a given trophicity. Specific examples of many of these physical, chemical and biological parameters characterizing the sea-atmosphere system and marine ecosystems and the processes taking place in them will be described and discussed in Part 2 of this series of articles (see Woźniak et al. (2011) in this issue). This will show distribution maps of some of these parameters in the Baltic Sea, produced using the algorithms of the SatBałtyk Operational System. These examples provide an ample illustration of the merits and potential uses of these algorithms. “
“The present article (Part 2) brings to a close the summary of the results of the first year and a half of SatBałtyk’s implementation.
