Threshold qualitative
Description of quantitative Threshold values: the threshold values are consistent with the approaches adopted by WFD and UNEP-MAP and are those published by Giani et al., 2024 as output of the EU MEDREGION project (Giani, M., Pavlidou, A., Kralj, M., Varkitzi, I., Borja, A., Menchaca, I., ... & Pagou, K. (2024). Assessment of the eutrophication status at Mediterranean sub-basin scale, within the European Marine Strategy Framework Directive. Science of The Total Environment, vol. 945, art. 173876). The threshold values are as follows: WT II: 6,9 umol/L; WT III: 1,6 umol/L.
The threshold values adopted in this subregion are the same as those established for the Western Mediterranean subregion and are as follows: WT IIW: 0,76 umol/L ; WT IIIW: 0,35 umol/L.
The threshold values adopted in this subregion are the same as those established for the Western Mediterranean subregion and are as follows: WT IIW: 1,2 ug/L ; WT IIIW: 0,48 ug/L.

Description parameter
Median 2016-2021. A definite proportion value of the MRU to be below TV in order for the criterion to be in good status has not been agreed or established at sub-regional level nor at national level. Nonetheless, considering the results obtained (over 98,86 % of the MRU is below the threshold value) we consider the status for this criterion to be good

For the 2 parameters used for D5C1, i.e. DIN and TP, a weighted average has been used (DIN= 4/7; TP = 3/7) in order to take into consideration the different level of uncertainty of the measurement.

Integration rule description criteria
A Multiparametric Index which equally combines the 3 primary criteria (D5C1, D5C2, D5C5, accounting for 33% each) has been used for the overall status assessment. For each pixel (25 km2) on the map, an assessment of GES/no GES has been made applying the type-specific threshold values. For DIN and TP within D5C1, a weighted average has been used (DIN= 4/7; TP = 3/7) in order to take into consideration the different level of uncertainty.
