Salinity and density share a positive relationship. As density increases, the amount of salts in the water—also known as salinity, increases. Various events can contribute to change in the density of seawater. Salinity can decrease from the melting of polar ice or increase from the freezing of polar ice.
Salinity is directly proportional to the density of Ocean water. In other words, As salinity increases, density of water also increases and vice-versa.

Hope this helps!
good job
