  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 +

  3. Salinity - Wikipedia

    en.wikipedia.org/wiki/Salinity

    Seawater typically has a mass salinity of around 35 g/kg, although lower values are typical near coasts where rivers enter the ocean. Rivers and lakes can have a wide range of salinities, from less than 0.01 g/kg [3] to a few g/kg, although there are many places where higher salinities are found. The Dead Sea has a salinity of more than 200 g ...

  4. Dead Sea - Wikipedia

    en.wikipedia.org/wiki/Dead_Sea

    The Dead Sea is receding at a swift rate; its surface area today is 605 km 2 (234 sq mi), having been 1,050 km 2 (410 sq mi) in 1930. Multiple canal and pipeline proposals, such as the scrapped Red Sea–Dead Sea Water Conveyance project, [11] have been made to reduce its recession.

  5. Water - Wikipedia

    en.wikipedia.org/wiki/Water

    The salinity of water in major seas varies from about 0.7% in the Baltic Sea to 4.0% in the Red Sea. (The Dead Sea, known for its ultra-high salinity levels of between 30 and 40%, is really a salt lake.) Tides are the cyclic rising and falling of local sea levels caused by the tidal forces of the Moon and the Sun acting on the oceans.

    The National Psoriasis Foundation recommends Dead Sea and Dead Sea salts as effective treatments for psoriasis. [ 5 ] [ 6 ] High concentration of magnesium in Dead Sea salt may be helpful in improving skin hydration and reducing inflammation, [ 7 ] although Epsom salt is a much less expensive salt that also contains high amounts of magnesium ...

    en.wikipedia.org/wiki/Specific_weight

    The specific weight, also known as the unit weight (symbol γ, the Greek letter gamma), is a volume-specific quantity defined as the weight W divided by the volume V of a material: = / Equivalently, it may also be formulated as the product of density, ρ, and gravity acceleration, g: = Its unit of measurement in the International System of Units (SI) is newton per cubic metre (N/m 3), with ...

  9. Sigma-t - Wikipedia

    en.wikipedia.org/wiki/Sigma-t

    Sigma-t is a quantity used in oceanography to measure the density of seawater at a given temperature. [1] σ T is defined as ρ(S,T)-1000 kg m −3, where ρ(S,T) is the density of a sample of seawater at temperature T and salinity S, measured in kg m −3, at standard atmospheric pressure.
