The difference between 34 ppt and 36 ppt salinity doesn’t sound very much, but it is enough to cause a difference in density. Even slightly denser seawater sinks below less dense water. However, the effect is greater if the salty water gets cold, as temperature has a greater effect on density than salinity ...
Understanding why the sea is salty begins with knowing how water cycles among the ocean's physical states: liquid, vapor, and ice. As a liquid, water dissolves rocks and sediments and reacts with emissions from volcanoes and hydrothermal vents. This creates a complex solution of mineral salts in our ocean basins. … See more Surface winds drive currents in the upper ocean.
