  • Seawater - Wikipedia
    Seawater, or sea water, is water from a sea or ocean On average, seawater in the world's oceans has a salinity of about 3 5% (35 g L, 35 ppt, 600 mM) This means that every kilogram (roughly one liter by volume) of seawater has approximately 35 grams (1 2 oz) of dissolved salts (predominantly sodium (Na+) and chloride (Cl−) ions)
  • Seawater | Composition, Properties, Distribution, Facts | Britannica
    Seawater, water that makes up the oceans and seas, covering more than 70 percent of Earth’s surface Seawater is a complex mixture of 96 5 percent water, 2 5 percent salts, and smaller amounts of other substances, including dissolved inorganic and organic materials, particulates, and a few atmospheric gases
  • Sea Water - National Oceanic and Atmospheric Administration
    One of the most well known qualities of the ocean is that it is salty The two most common elements in sea water, after oxygen and hydrogen, are sodium and chloride Sodium and chloride combine to form what we know as table salt Sea water salinity is expressed as a ratio of salt (in grams) to liter of water, It is written parts per thousand (ppt)
