WebApr 20, 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. WebMar 28, 2024 · Water with a salinity of 17ppt freezes at about 30°F (-1°C) and 35ppt water freezes at about 28.5°F (-2°C). However, sea ice itself contains very little salt, about a tenth of the amount of salt that sea water has. This is because ice will not incorporate salt into its crystal structure. Newly formed sea ice can trap pockets of salty water ... WebThe concentration of salt in seawater (salinity) varies with temperature, evaporation, and precipitation.
