How is seawater's salinity expressed

Web20 apr. 2024 · The electrical conductivity of seawater ranges from 44,000 to 58,000 µmhos/cm (or µS/cm) with an average of about 50,000 µmhos/cm. Of course, conductivity and salinity are highly and positively correlated. A multiplier of 0.69 may be used to convert conductivity to salinity for practical purposes. The pH of seawater ranges from 7.6 to 8.4. Web1 jan. 2024 · For example, ocean water typically has about 35 grams of salt in one kilogram of water, so its salinity can be expressed as 35/1000 or 0.035. This can also be expressed as 3.5% or 35 parts per thousand (ppt). Salinity is often used to describe seawater and brackish water, but it can also be used to describe fresh water and brines.

Salinity was formerly … WebOn average, sea surface salinity is about 35 PSS. Over the globe, sea surface salinity varies from 32 to 37 PSS. Salinity variations are caused by precipitation, evaporation, runoff, and ice freezing and melting. Seawater's density – mass per volume – is governed by temperature, salinity, and depth. Ocean circulation below the wind-driven ... WebSalinity is expressed by the amount of salt found in 1,000 grams of water. Therefore, if we have 1 gram of salt and 1,000 grams of water, the salinity is 1 part per thousand, or 1 ppt. The average ocean salinity is 35 ppt. This number varies between about 32 and 37 ppt. Rainfall, evaporation, river runoff, and ice formation cause the variations. cryptic female choice example
