How does salinity differ in a river, estuary, and an ocean?

Answer:

  • Because fresh water flowing into the estuary is less salty and less dense than water from the ocean, it often floats on top of the heavier seawater.
  • For example, a heavy spring rain, or a sustained shift in local winds, can drastically affect the salinity in different parts of an estuary
