Question

Arabian sea salinity​

Answer 1

Answer:

The Arabian Sea has a dense, high-salinity layer (37 parts per thousand) to a depth of about 400 feet (120 metres) because of high evaporation.

Answer 2

Answer:

here is your answer mate

Explanation:

The Arabian Sea has a dense, high-salinity layer (37 parts per thousand) to a depth of about 400 feet (120 metres) because of high evaporation rates at subtropical temperatures with moderate seasonal variations. Salinity in the surface layer of the Bay of Bengal is considerably lower, often less than 32 parts per thousand, because of the huge drainage of fresh water from rivers. High surface salinity (greater than 35 parts per thousand) is also found in the Southern Hemisphere subtropical zone between 25° and 35° S; while a low-salinity zone stretches along the hydrological boundary of 10° S from Indonesia to Madagascar. Antarctic surface-water salinity generally is below 34 parts per thousand.
