WebWhen the Practical Salinity Scale was adopted by oceanographers, they defined salinity as follows: a seawater of salinity 35 (S = 35) has a conductivity ratio of unity with a solution of 32.4356 grams of potassium chloride in 1 kg of solution at 15C and 1 atmosphere. This value for salinity was determined by extensive testing of seawater samples. WebMuch like percentage, parts per thousand (ppt) is a ratio often used to refer to the concentration of solutes in solutions, such as salts in water (i.e. salinity). “The average salinity in ocean water”, you will read in most introduction to oceanography textbooks, “is 35 ppt”. But in reality, “hardcore scientists” do not use ppt as ...
