Dissolved materials in soft fresh water vary in amount from prac- tically zero to about 65 parts per million. Lakes and ponds with hard water exhibit a variety of higher values for salt content, but the value given in the table, 300 ppm, is representative. Salt lakes may contain exceptionally large amounts of dissolved substances. In contrast to the extreme variability in the salt content of inland waters, the open ocean tends to remain highly uniform in salinity over huge areas (Fig. ). A fish could swim up the middle of the Atlantic Ocean, for example, from the Cape of Good Hope almost Fig. The surface salinity of the Atlantic Ocean.
