  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. Specific weight - Wikipedia

    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 ...

  5. 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.

  6. Mass concentration (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Mass_concentration_(chemistry)

    Liquid water has a density of approximately 1 g/cm 3 (1 g/mL). Thus 100 mL of water is equal to approximately 100 g. Thus 100 mL of water is equal to approximately 100 g. Therefore, a solution with 1 g of solute dissolved in final volume of 100 mL aqueous solution may also be considered 1% m/m (1 g solute in 99 g water).

  7. TEOS-10 - Wikipedia

    en.wikipedia.org/wiki/TEOS-10

    In the SIA-Library of TEOS-10 implementations to convert outdated into current scales are included. [11] TEOS-10 was derived using absolute pressure P while EOS-80 used the pressure relative to the sea surface 𝑝 sea. They can be converted by: P/Pa = 101325 + 10000 ∙ 𝑝 sea /dbar (see Atmospheric Pressure).

  8. Total dissolved solids - Wikipedia

    en.wikipedia.org/wiki/Total_dissolved_solids

    where TDS is expressed in mg/L and EC is the electrical conductivity in microsiemens per centimeter at 25 °C. The conversion factor k e varies between 0.55 and 0.8. [5] Some TDS meters use an electrical conductivity measurement to the ppm using the above formula. Regarding units, 1 ppm indicates 1 mg of dissolved solids per 1,000 g of water. [6]

  9. Oceanic freshwater flux - Wikipedia

    en.wikipedia.org/wiki/Oceanic_freshwater_flux

    Sea ice is considered as part of the oceanic water budget, therefore, its melting or freezing states not an input or output of water in general. However, at a regional scale and intraannually timescale, it can present an important determinator of ocean salinity, by adding freshwater during melting process or by rejecting salt during the ...
