n. The saltwater of a sea or ocean.


n. water containing salts; "the water in the ocean is all saltwater" [syn: saltwater, brine] [ant: fresh water]


Seawater, or salt 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, or 599 mM). This means that every kilogram (roughly one litre by volume) of seawater has approximately of dissolved salts (predominantly sodium and chloride ions). Average density at the surface is 1.025 kg/ l. Seawater is denser than both fresh water and pure water (density 1.0 kg/l at ) because the dissolved salts increase the mass by a larger proportion than the volume. The freezing point of seawater decreases as salt concentration increases. At typical salinity, it freezes at about . The coldest seawater ever recorded (in a liquid state) was in 2010, in a stream under an Antarctic glacier, and measured . Seawater pH is typically limited to a range between 7.5 and 8.4. However, there is no universally accepted reference pH-scale for seawater and the difference between measurements based on different reference scales may be up to 0.14 units.
