Answer 1

Answer:

Salinity is the saltiness or amount of salt dissolved in a body of water, called saline water (see also soil salinity). This is usually measured in {\displaystyle {\frac {g\ {\textrm {salt}}}{kg\ {\textrm {sea}}\ {\textrm {water}}}}}{\displaystyle {\frac {g\ {\textrm {salt}}}{kg\ {\textrm {sea}}\ {\textrm {water}}}}} (note that this is technically dimensionless). Salinity is an important factor in determining many aspects of the chemistry of natural waters and of biological processes within it, and is a thermodynamic state variable that, along with temperature and pressure, governs physical characteristics like the density and heat capacity of the water.

A contour line of constant salinity is called an isohaline, or sometimes isohale.

Answer 2

Answer:

Because ocean water is so salty of course. The concentration of dissolved salt in a given volume of water is called salinity. Salinity is either expressed in grams of salt per kilogram of water, or in parts per thousand (ppt, or ‰).
