Did you know the Atlantic Ocean is saltier than the Pacific

The Atlantic Ocean does have a higher salinity than the Pacific Ocean [1]. There are a couple of reasons for this:

• Freshwater input: Large rivers like the Amazon pour a lot of freshwater into the Atlantic, diluting the salt concentration in some areas. However, the Atlantic is a more enclosed basin compared to the Pacific, so the overall salinity stays higher.

• Evaporation and precipitation patterns: The Pacific experiences more rainfall near the equator, further reducing surface water salinity. The Atlantic has a stronger north-south circulation pattern that helps to trap saltier water in its depths.
