The Free Water Body subprogram (Table 4, #8.2.4) aims to describe the effects of primarily overfertilization by means of hydrographical, chemical, and biological methods. One part of the program collects samples as frequently as 18 to 25 times per year at a few sea and coastal stations. Another part collects samples only once per year, during winter, to map the extent of areas with low oxygen content and the size of the nutrient pool, which gives the prerequisites for algal bloom in spring.
