  2. Seawater - Wikipedia

    en.wikipedia.org/wiki/Seawater

    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 +

    en.wikipedia.org/wiki/Salinity

    Annual mean sea surface salinity for the World Ocean. Data from the World Ocean Atlas 2009. [1] International Association for the Physical Sciences of the Oceans (IAPSO) standard seawater. Salinity (/ s ə ˈ l ɪ n ɪ t i /) is the saltiness or amount of salt dissolved in a body of water, called saline water (see also soil salinity). It is ...

    TDS meter – used for checking of Total Dissolved solids of a liquid. Saline (medicine) – A saline solution being isotonic with that of human blood is 0.9% w/v, c. 300 mOsm/L (and this being the same as the salinity of the ocean is a common myth. The ocean on average has a much higher concentration of sodium chloride as well as many other salts.

  5. CTD (instrument) - Wikipedia

    en.wikipedia.org/wiki/CTD_(instrument)

    A CTD instrument is an oceanography sonde (French for probe) used to measure the electrical conductivity, temperature, and pressure of seawater. The pressure is closely related to depth. Conductivity is used to determine salinity. The CTD may be incorporated into an array of Niskin bottles referred to as a carousel or rosette. The sampling ...

    en.wikipedia.org/wiki/Deep_ocean_water

    Deep ocean water has a very uniform temperature, around 0–3 °C (32–37 °F), and a salinity of about 3.5% or, as oceanographers state, 35‰ (parts per thousand). [ 3 ] In specialized locations, such as the Natural Energy Laboratory of Hawaii , ocean water is pumped to the surface from approximately 900 m (3,000 ft) deep for applications in ...

  7. List of bodies of water by salinity - Wikipedia

    en.wikipedia.org/wiki/List_of_bodies_of_water_by...

    This is a list of bodies of water by salinity that is limited to natural bodies of water that have a stable salinity above 0.05%, at or below which water is considered fresh. Water salinity often varies by location and season, particularly with hypersaline lakes in arid areas, so the salinity figures in the table below should be interpreted as ...
