Quizplus · Accepted Answer

At high latitudes, the salinity of ocean water is generally lower near the surface due to the input of fresh water from melting ice and precipitation. This fresh water dilutes the surface salinity. As you go deeper, the influence of these fresh water sources decreases, and the salinity increases.
