Description parameter |
Underground flows in most of the islands are higher than surface run-off, accounting for 53.2 % of the total on the island of Flores, 55.0 % in Santa Maria, 67.9 % in São Miguel, 75.7 % in Terceira and 85.6 % in São Jorge. and 89.7 % in Graciosa
|
Higher values of chlorophyll are recorded for the northern area of the Exclusive Economic Zone surrounding the EEZ of the Azores together with the adjacent area of the extended continental shelf claimed by Portugal, i.e. between 28° and 40° N, 17° and 41° W, whereas variability has been higher in...
|
On the island of São Miguel, for a total of 38 samples, 22 were positive for the occurrence of PSts. 7 absorption values were thus detected above the legal threshold for two starfish species (Ophidiaster ophidianus and Marthasterias glacialis) followed by molluscs belonging to the species Stronit...
|
On the islands of São Miguel, Santa Maria and Terceira, it was observed that the depth values of the euphotic zone varied between 30 and 130 m, 20 m and 105 m and 53 m and 130 m respectively. In addition, values for the euphotic area of 33 m and 4 m respectively...
|
In the Azores, dissolved oxygen concentrations in seawater show a variation of approximately 5 to 6 ml/l (surface) to < 4 ml/l in the deep water areas, with, on the surface, a tendency to increase and decrease respectively to the north and south and south-east of the Azores. Winter a...
|
In the Azores, there are sites without registration of opportunistic species and the maximum figure for the average proportion of these species was 0.38 for the island of Santa Maria. 4 species of opportunistic macroalgae have been identified: Chaetomorpha pachynema, Ulva Compressa, Ulva intestin...

The Azores vary widely and seasonally in oceanographic conditions. Given the high exposure of the coasts of the Azores islands resulting from their oceanic position associated with high seas and a strong wave, as well as the great distance between them, the oligotrophic nature of marine water bod...
|
The concentrations of the sea chlorophyll are not particularly high in the Region of the Azores, with these low values, together with other chemical parameters, one of the indicators confirming the marine oligotrophic nature of the Azores-Madeira region. However, it is recognised that the annual ...
|
Not qualitatively or quantitatively assessed as they require further studies on the subject, including monitoring of the occurrence and patterns of evolution of the various toxic substances which have been identified in the meantime. However, some important aspects regarding algal blooms and the ...
|
The Azores being a oligotrophic region that is open in an open ocean area, the light is not a limiting factor and the occurrence of most nutrients is expected at the surface level by a dynamic process, such as an oceanic filament or a redemolition. However, the depth of the euphotic area is small...
|
In the Azores region, although there is a clear link between the depth and the oxygen (dissolved oxygen, apparent use of oxygen and oxygen saturation) and the nutritional parameters (nitrates, phosphates and silicates), some distinct spatial patterns have been observed, which appear to show some ...
|
There is, in the Azorean coastal areas in general, an ecological quality that can be considered as Good and/or Eled. Furthermore, according to all water bodies analysed, they meet the environmental requirements established by the WFD, where most of them are of high quality. [reference to: Please see attached written report]

Not applicable to the Azores. [further details and related bibliographic references are available in the written report]
|
In the Azores, the inter-tidal communities have a smaller variety of invertebrates associated with them compared to other regions of the Atlantic, which is probably due to the lesser extent of their inter-tidal biotopes resulting from very high wave power and high wave power. However, despite the...

As a result of agricultural fertiliser application on grassland, nitrogen leaching is an environmental pressure factor that negatively affects water quality in the Azores. Groundwater discharges, usually characterised by a higher concentration of nutrients, are an important element of the ocean?s...
|
The same increase is due to the rapid cooling of the ocean associated with the passage of storms and the resulting conds-to-water phenomena of the mixing of water bodies as well as the input of nutrients from the deeper areas of the thermoclina and the transport of phytoplanktonic cells from the ...
|
There is little information about phytoplankton, although there is some knowledge about algal blooms in other parts of the world, with the most common sources of nutrients corresponding to the domestic effluents, the run-off of intensive farming activity as well as the food industry?s effluents. ...
|
In the eiphic area (15 m), the development of a 40 registered biocenosis biocenosis in the euphotic zone has been observed after a year of exposure, but there has been a reduction in icnodiversity from the depth of 15 m due to a limitation on light availability associated with a gradual...
