Integration rule description for parameters | BEAST integrates parameters based on their weight. In this case, we considered causes (25%-TP, 25%-NO2, 25%-NO3, 25%_NH4) and effects (50%Chlorophyll and 50% transparency) against national legislation (Ord.161/2006). BEAST integrates parameters based on their weight. In this case, we considered causes (25%TP, 25%NO3, 25%NO2, 25% NH4)) and effects (50%Chlorophyll and 50% transparency) against national legislation (Ord.161/2006). BEAST integrates parameters based on their weight. In this case, we considered causes (50% DIP and 50%DIN) and effects (50%Chlorophyll and 50% transparency) against GES. |

Integration rule description for criteria | TRIX and EQR M-AMBI(n) ecological indexes were used to integrate eutrophication indicators in the coastal MRUs. TRIX taking into consideration causes -nutrients (DIP and DIN) and effects (chlorophyll a and oxygen saturation) (Vollenweider et al. (1998)) and M-AMBI(n) (Sigovini et al., 2013) was used for assessing adverse effects on benthic macroinvertebrates. |
BEAST - Black Sea Eutrophication Assessment Tool. A tool similar to HEAT (HELCOM) developed for the Black Sea into Baltic2Black Project. Due to the different area, parameters, and features, BEAST was calculated taking into consideration causes - nutrients (DIP and DIN) and effects (chlorophyll a and transparency) calculated for each station. Between parameters and criteria, BEAST uses OneOutAllOut principle and EQR and gives a qualitative score - High, Good, Moderate, Poor and Bad. The threshold between Good and Moderate is considered as GES. BEAST - Black Sea Eutrophication Assessment Tool. A tool similar to HEAT (HELCOM) developed for the Black Sea into Baltic2Black Project. Due to the different area, parameters, and features, BEAST was calculated taking into consideration causes - nutrients (TP, nitrate, nitrite, and ammonia) and effects (chlorophyll a and transparency) calculated for each station. Between parameters and criteria, BEAST uses OneOutAllOut principle and EQR and gives a qualitative score - High, Good, Moderate, Poor and Bad. The threshold between Good and Moderate is considered as GES. |
