| GES description | D5 Eutrophication |
Good ecological status is achieved when the biological community is in balance and retains all necessary functions in the absence of adverse disturbances associated with eutrophication (e.g. excessive phytoplankton growth, low oxygen concentrations, etc.) and/or when there are no impacts related to excessive nutrient enrichment of waters on the sustainable use of ecosystem goods and services. Good ecological status is achieved when: - either nutrient levels are not high (criterion 5.1) and there are no direct (criterion 5.2) or indirect (criterion 5.3) impacts related to excessive nutrient enrichment of waters on the sustainable use of ecosystem goods and services; - or there are no direct impacts (criterion 5. 2) or indirect (criterion 5.3) impacts of excessive nutrient enrichment of waters on the sustainable use of ecosystem goods and services, despite high nutrient levels (criterion 5.1).

Evtrofikacija zaradi dejavnosti človeka, in njeni škodljivi učinki, kot so upad biotske raznovrstnosti, degradacija ekosistemov, škodljiva cvetenja alg in pomanjkanje kisika v spodnjih plasteh voda, je minimalna. |
In order to achieve GES in the marine environment, it is necessary to keep nutrients -compounds of nitrogen and phosphorus – in the water column at levels which do not accelerate primary production. If there is no excess organic matter and increased suspended algae, water transparency will be satisfactory allowing photosynthesis process to evolve naturally and allow perennial seaweeds and sea grasses to grow. In addition, chlorophyll concentration in the water column will not be increased and oxygen levels will establish a satisfactorily oxygenated environment without anoxic or hypoxic conditions. When an ecosystem is in GES the nutrients are preserved at moderate levels and any human-induced eutrophication phenomena are prevented. Hence, the floristic composition of the marine environment is not altered disturbing the diatom to flagellate ratio, or causing toxic algal blooms. As a result, the ecosystems retain their balance and biodiversity is preserved. Therefore, the overall quality of the marine environment is maintained.In the subregion examined it is deemed that only a maximum proportion of 5% of the assessment area is not in Good Environmental Condition, and as a result occasionally presents eutrophication phenomena due to anthropogenic intervention. There are particular hot spots in coastal areas, mainly enclosed gulfs, where nutrients concentrations exceed threshold values as a result of land –based or sea based human activities; Amvrakikos Gulf and Patraikos Gulf. |
The marine environment of Cyprus is considered to be in good environmental status by the year 2020 if human-induced eutrophication is minimised, especially adverse effects thereof, such as losses in biodiversity, ecosystem degradation, harmful algae blooms and oxygen deficiency in bottom waters. |

V obalnih predelih je mejna vrednost dobrega okoljskega stanja določena z vrednostjo indeksa za makroalge EEI-c. V odprtih vodah je stanje dobro, ko evtrofikacija zaradi dejavnosti človeka ne povzroča škodljivega cvetenja. |

Na sedimentnem dnu infralitorala je dobro okoljsko stanje določeno s primernim stanjem travnikov morskih cvetnic. V odprtih vodah je dobro okoljsko stanje določeno s prostorsko in časovno razporeditvijo koncentracij raztopljenega kisika v pridnenem sloju. Dobro okoljsko stanje predstavljajo razmere, ko so epizode pomanjkanja kisika (hipoksije) v pridnenem sloju časovno in prostorsko tako omejene, da ne povzročajo trajnih poškodb habitatov na morskem dnu. |
