Does open oceand have both saltwater and freshwater?

The open ocean does not have freshwater. It contains saltwater, which is a mixture of water and various dissolved salts, including sodium chloride (NaCl), commonly known as table salt. The open ocean is characterized by high salinity levels due to the accumulation of these dissolved salts over time. Freshwater, on the other hand, has a low concentration of dissolved salts and is typically found in lakes, rivers, streams, and glaciers.
