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
Anthropometry of the upper arm anthropometric measures of the upper arm are the upper arm length, the triceps skin fold (TSF), and the mid-upper arm circumference (MUAC). The triceps skin fold is the width of a fold of skin taken over the triceps muscle. It is measured using skinfold calipers. (See body fat percentage#Skinfold methods for general information on skinfold fat measurements.) The measurement is taken at a standardized position (one of eight standard skinfold measurement points) at the midpoint of the back of the upper arm. The skinfold calipers are spring-loaded. Holtain skinfold calipers are marked with 0.2 mm gradation, Lange calipers with 0.5
