Where in the ocean would salinity be highest?

Salinity is highest in the subtropics, between 30°N and 30°S latitude. This is because the subtropical zones are characterized by high levels of evaporation, which leads to a decrease in water volume and an increase in salt concentration. Additionally, the subtropical zones are located away from major sources of freshwater, such as rivers and glaciers, which can dilute the salinity of the ocean. As a result, the subtropical oceans are the saltiest regions in the world, with salinity levels reaching up to 37 parts per thousand (ppt).
