• Salinity
  • How salty the water is. Brine has a very high salinity. Fresh water has a salinity of zero.
Abstract from DBPedia
    Salinity (/səˈlɪnɪti/) is the saltiness or amount of salt dissolved in a body of water, called saline water (see also soil salinity). It is usually measured in g/L or g/kg (grams of salt per liter/kilogram of water; the latter is dimensionless and equal to ‰). Salinity is an important factor in determining many aspects of the chemistryof 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.

    塩分濃度(えんぶんのうど、英: salinity)は、水に溶けている塩(えん)の量である。ここで言う「塩分」とは、塩化ナトリウム(NaCl) だけでなく、硫酸マグネシウム(MgSO4) や硫酸カルシウム(CaSO4)そして炭酸水素塩などの塩類を含める場合が多い。 オーストラリアや北アメリカでは、この語が往々にして土壌に含まれる塩分を示唆し得る。
