The five ocean basins, the Atlantic Ocean is the saltiest. On average, there is a distinct decrease of salinity near the equator and at both poles, although for different reasons. Near the equator, the tropics receive the most rain on a consistent basis.
Intruiging… What is in equator that makes the salinity high? Or why is it more salty in Atlantic?
Atlantic is below the equator which makes it salty because of the icebergs that are being melted and also from the poles that surrounds it. That makes the salinity higher.
If Atlantic is really salty, can people swim there? Or dive?
Yes, there are beaches near Atlantic where you can swim. Swimming in Atlantic itself is still allowed with the guidance of life guards. Also remember to bring floats and follow their instructions on what area is swimmable.
