Welcome To Whitehall Township Whitehall Township is located in the center of the Lehigh Valley. The Township is one hour north of Philadelphia and an hour and half from New York City.
SALINITY OVERVIEW Salinity is the concentration of dissolved salts in water, usually expressed in parts per thousand (ppt). Objects float higher in salt water than fresh water because salt water is denser (heavier per unit of volume).
Conductivity is the measure of a materialâs ability to conduct an electric current. In ocean sciences, the electrical conductivity of seawater is used as an indication of salinity. The saltier the water, the higher the conductivity will be.Seawater salinity can be calculated from measured values of conductivity and temperature. Salinity refers to the amount of salts dissolved in water, expressed as parts per thousand, or ppt.This corresponds to the amount of salt in grams dissolved in 1000 grams of water. However, salinity is difficult to measure directly and is generally calculated from conductivity and temperature measurements.he saltier the water, the higher the conductivity will be. Seawater salinity can be calculated from measured values of conductivity and temperature. Salinity refers to the amount of salts dissolved in water, expressed as parts per thousand, or ppt.
