The Atlantic from the River Amazon, up to 300,000 cubic metres per second in the rainy season
Estuaries place can meet ocean and fresh water
Ocean water has salt and other minerals, but fresh water has no salt. Fresh water also has minerals in it, but ocean water has more.

The Pacific Ocean is salty, there is no fresh water in it.
The photic zone of the ocean is the surface of the ocean that receives sunlight.
Estuaries place can meet ocean and fresh water
rain, snow, and melting ice add fresh water to the ocean, lowering the salinity there. Salinity is also lower near the mouths of large rivers. These rivers empty great amounts of fresh water into the ocean.
Most sharks remain in the ocean, while some species of the Bull Shark (Ganges and Lake Nicaragua) have adapted to fresh water. Great Whites can briefly tolerate fresh or brackish water, also.
Ships need more ballast in the ocean because the salt helps to keep them a float.What we know is that salt water is about 3% more dense than fresh water and that ships use the water they are floating in for ballast.Say an ocean ship needs 10 tonnes of ballast to get to it's stable water line. The volume of 10 tonnes of seawater would equal 9.7m3.That same ship will float slightly lower in fresh water since fresh water is less dense. It will need 3% less ballast weight (9.7 tonnes) to get to the same stable water line in fresh water. The volume of 9.7 tonnes of fresh water would equal 9.7 m3.So, the ship in the ocean requires 3% more ballast weight than the ship in fresh water, but the ballast volume is the same in both cases.
fresh water doesnt have saltinity in it but, ocean water does.
The ocean is salt water.
The volume of Pacific ocean is 660,000,000 Km3
Volume of pacific ocean is 1.4*10^20
Salt water is more dense than fresh water. The salts and minerals in ocean water have more mass/volume than the water. So, the total density is greater .
