Accumulation of pressures that may cause the significant modification of the salinity regime in the South Atlantic Demarcation (EM SUD PRE Salinity)

To identify those areas of the South Atlantic Demarcation whose saline regime can be significantly altered, a semi-quantitative index has been developed that takes into account all the elements described below: All cells located less than 5 km from: some sewage plants, municipalities with desalination capacity (in the absence of the location of the discharge points) and the mouths of rivers that may be altered by regulatory issues (assuming that anything further away is likely to affect rivers or transitional waters and would therefore not directly alter coastal waters). Double scores have been awarded to sewage plants designed for more than 100,000 equivalent inhabitants. In addition, 0.25 has been added to cells matching a wastewater discharge. Finally, everything has been added, being the resulting range of values: Very High: 6 to 7.25/High: 5 to 6/Medium: 2 to 5/Low: 1 to 2/Very Low: minor 1
