Sea of Marmara about 22 parts per thousand, which is slightly greater than that of the Black Sea, but only about two-thirds that of most oceans. The water is much more saline at the sea bottom, averaging salinities of around 38 parts per thousand, similar to that of the Mediterranean Sea. This high-density saline water, like that of the Black Sea, does not migrate to the surface. Water from the Susurluk, Biga (Granicus) and Gonen Rivers also reduces the salinity of the sea, though with less influence than on the Black Sea. With little land in Thrace draining southward, almost all of these
Body water those rich in water, such as plants, raw meat, and fish. The amount of this water that is retained in animals is affected by several factors. Water amounts vary with the age of the animal. The older the vertebrate animal, the higher its relative bone mass and the lower its body water content. In diseased states, where body water is affected, the fluid compartment or compartments that have changed can give clues to the nature of the problem, or problems. Body water is regulated by hormones, including anti-diuretic hormone, aldosterone and atrial natriuretic peptide. Volume contraction is a decrease in
