Achieve good and avoid deterioration of the sediment bottom in relation to the condition of the marine phanerogflowers.

Orthophosphate (PO4) to 4,6 ?g/L.

The water column maintains a situation where there is no excessive phytoplankton flowering, and the composition of the phytoplankton organisation is typical for the anthropogenic relatively unladen environment. The existing good status with regard to the concentrations of chlorophyll a is maintained. The concentration of chlorophyll a in the surface layer of sea water does not exceed the limit value for good status determined by intercalibration at the level of the region of the Mediterranean Sea: 1,5 ?g/L.

The current good state of transparency is maintained in the light of the specific situation of marine waters, in the competence of R Slovenia. The annual average values of transparency shall not exceed the indicative transparency threshold set at national level: 6.1 m.

The dissolved oxygen concentrations at the bottom must be suitable for the survival of demersal fauna. An episode of oxygen deficiency (hypoxia) in the bottom layer of the water column should be so limited in time and place that it does not cause the demersal organisms and permanent damage to the seabed. The total lack of oxygen at the bottom (anoxj) must not occur. The existing good status is maintained. The dissolved oxygen concentrations at the bottom may not be below 2 mg/L, which is the pituxial limit.
