Threshold qualitative
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 IIW: 6,9 umol/L; WT IIIW: 1,6 umol/L.
The threshold values applied are consistent with the results of the Mediterranean Intercalibration exercise for the BQE Phytoplankton (cfr. Giovanardi et al., Ecological Indicators 93 (2018) 316-332) and with the decisions made by UNEP-MAP (UNEP/MED WG 563/7). The threshold values are as follows: WT IIW: 0,76 umol/L coastal; WT IIIW: 0,35 umol/L.
The threshold values applied are those established by Commission Decision 2018/229 for Type IIW (West) coastal waters and Type IIIW (West) coastal waters, hence are coherent with the WFD approach. These threshold values are consistent with decisions made by UNEP-MAP (cfr. Giovanardi et al., Ecological Indicators 93 (2018) 316-332, and UNEP/MED WG 563/7). The threshold values are as follows: WT IIW: 1,2 ug/L coastal; WT IIIW: 0,48 ug/L.

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 99,17 % of the MRU is below the threshold value) we consider the status for this criterion to be good

Pressures have decreased (nutrient loads from riverine inputs and urban watewaters)
Analysis of % variation of surface chl 'a' concentration from Copernicus data shows a negative trend (increased concentration) in most of the MRU, hence the general trend of the element is improving. Nonetheless, localised positive trends have been registered in coastal areas of the Gulf of Salerno and the Gulf of Gaeta.
No hypoxias or anoxias events have been registered

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.
