There is a possibility that nutrients of anthropogenic origin may be introduced from the ?Coastal waters? of this area. The situation is more acute in this area due to the pattern of movement of marine waters and the short distance between the coast and the geographical outer limit defined for the coastal area. However, there are no registers on de-oxygenation in this area.

Information on oxygen, phosphorus, nitrogen and organic matter is missing for this area. However, the majority is the deep and deep sea, where the height of the water column ranges from 200 to 4 000 m. Based on satellite data it was possible to infer that they are areas with low nutrient and low chlorophyll concentration. Nutrient deposition of air origin is not expected to have impacts on benthic and pelagic ecosystems due to the rapid assimilation of the surface into the area and the activities of anthropogenic origin that could lead to the eutrophication of the environment by far and the assessment of the ?Intermedium waters?, despite the degree of reliance at LOW, shows that there is no risk of nutrient inputs or organic matter that could cause changes in benthic biotopes.

The data available in this area show an enrichment of nutrients as a result of plumes from the estuaries that flow into this area, similar to what was observed in the initial assessment report. However, it should be noted that an increase in Chlorophyll a is not observed. The distribution of Chlorophyll-Satellite is similar to that reported in the initial assessment report. Existing data made it possible to identify small areas with oxygen deficiency in the port areas. The average of phytoplankton-producing events (blooms) of marine biotoxin-producing phytoplankton between 2012 and 2016 was 28 events, compared to 53 events in the previous period (2006-2011). It was not possible to establish an area with the greatest occurrence of these events due to the one-off nature of these events. Studies on benthic invertebrate communities show the presence of communities adapted to the type of substrate without signs of structural changes compatible with eutrophication of the environment, such as the appearance of opportunistic species. In contrast, other studies highlight the degradation of macroalgal communities as a result of the introduction of anthropogenic nutrients from the Mondego estuary, and even predict a loss of seagrass beds by 2050. The assessment area receives drainage from the hydrographic basins from Minho and Lima, from Cávado, Ave and Leça, from Douro, from Vouga, Mondego and Lis. Within the scope of the WFD, it appears that the total area covered by the various hydrographic basins, classified as REASONABLE/MEDIOCRE is extensive (about 45% of the total area). The classification attributed by the WFD is the result of the combination of ecological status/potential and chemical status, but it does not allow distinguishing whether the classification is due only to the influence of nutrients. Using the criteria and data available for this assessment it is concluded that the conditions reported in the initial assessment report are maintained. Thus, it is considered that this area reached GES, even though the degree of confidence in this assessment is low due to the reduced number of data and criteria used.

There is evidence of nutrient enrichment, but no excessive increase of Chlorophyll a. the distribution of Chlorophyll ? is similar to the one reported in the initial assessment report. There are no reports of oxygen deficiency areas and the average phytoplankton blooms producer of marine biotoxins is similar to the one observed during the initial assessment period, i.e. about 28 events. However, it is not possible to establish the area of influence of these events due to their one-off nature. The insufficiency of benthic data does not allow to conclude on the existence of benthic community changes due to the anthropogenic input of nutrients. In this area rapidly reaching depths up to 100 m, particularly in the Central South region, by drastically reducing the area that could be affected by these changes. The BC area comprises the water catchment areas of the Tagus and Ribeiras do Oeste, Sado and Mira and Ribeiras do Algarve. According to the classification of the WFD, 35 % of the coastal water bodies associated with the Tajo and Ribeiras do Oeste river scored BOM and 65 % of INSUREFFICIENT. Of the water bodies associated with the Sado and Mira river basins, 67 % was classified as BOM and 22 % as KNOWN. The classifications attributed to the water bodies associated with Ribeiras do Algarve were: Excellent (44 %), BOM (44 %) and RAZOABLE (12 %). As a result of the above, it is considered that the area BC has reached the Good Environmental State. The confidence level of this assessment is low and is justified by the limited number of data and criteria used.

The satellite Chlorophyll-satellite data show that, compared to the 2012 valuation, the situation remains unchanged.
In this area the risk of introduction of nutrients from ?Coastal waters? to ?Intermedium? is relatively low, given their large area and the consequent dilution effect of the increased distance to the coast. It is not expected that there will be an increase of nutrients in these waters by anthropogenic introduction, or even because of atmospheric deposition and thus deoxygenating because of this.

Information on oxygen, phosphorus, nitrogen and organic matter is missing for this area. However, the majority is the deep and deep sea, where the height of the water column ranges from 200 to 4 000 m. Based on satellite data it was possible to infer that they are areas with low nutrient and low chlorophyll concentration. Nutrient deposition of air origin is not expected to have impacts on benthic and pelagic ecosystems due to the rapid assimilation of the surface into the area and the activities of anthropogenic origin that could lead to the eutrophication of the environment by far and the assessment of the ?Intermedium waters?, despite the degree of reliance at LOW, shows that there is no risk of nutrient inputs or organic matter that could cause changes in benthic biotopes.

There is no evidence of nutrient enrichment in this area, but an excessive increase of chlorophyll a is observed in the coastal zone adjacent to the river Guadiana. The distribution of Chlorophyll-Satite is similar to the one reported in the initial assessment report. There are no reports of oxygen deficiency areas, but the average phytoplankton blooms of marine biotoxins is higher than in the initial assessment period. As observed in the remaining areas, it is not possible to establish the catchment area of these events due to the one-off nature of these events. Insufficient benthic data also does not support the conclusion that there are changes in benthic communities due to anthropogenic input of nutrients This area comprises the water catchment areas of the Guadiana and Ribeiras do Algarve. Under the WFD, BOM classification has been assigned to coastal water bodies associated with Ribeiras river basins of the Algarve, and RAZOBLE water bodies associated with the Guadiana river basin. This area, however, represents less than 5 % of the CC area. For this reason, it is considered that this assessment area has reached the Good Environmental State, albeit with a low degree of confidence, due to the limited number of data and criteria used.
