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, 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 … See more Salinity Although the vast majority of seawater has a salinity of between 31 and 38 g/kg, that is 3.1–3.8%, seawater is not uniformly saline throughout the world. Where mixing occurs with … See more The water in the sea was thought to come from the Earth's volcanoes, starting 4 billion years ago, released by degassing from molten rock. More recent work suggests much of … See more Accidentally consuming small quantities of clean seawater is not harmful, especially if the seawater is taken along with a larger quantity of fresh water. However, drinking … See more ASTM International has an international standard for artificial seawater: ASTM D1141-98 (Original Standard ASTM D1141-52). It is used in … See more Climate change, rising levels of carbon dioxide in Earth's atmosphere, excess nutrients, and pollution in many forms are altering global oceanic geochemistry. Rates of change for some aspects greatly exceed those in the historical and recent geological record. … See more Minerals have been extracted from seawater since ancient times.

WebSalinity Conversion Calculator. This calculator converts between various units of salinity. Note that relative specific gravity (sg) and conductivity (mS/cm) measurements are inheritly temperature-dependent and that this calculator follows the prevailing standard of assuming a temperature of 25C/77F. Most salinity measurements in literature ... WebTherefore, the specific gravity (which is dimensionless) for a liquid has the same numerical value as its density in units of g/cm3. Since the density of a fluid varies with temperature, … ejse studio
