Question
Describe the salinity variation in the Pacific Ocean.
Solution
The salinity variation in the Pacific Ocean:
i. The salinity variation in the Pacific Ocean is mainly due to its shape and larger areal extent.
ii. Salinity decreases from 35 o/oo - 31 o/oo on the western parts of the northern hemisphere because of the influx of melted water from the Arctic region.
iii. In the same way, after 15° - 20° south, it decreases to 33 o/oo.
