Explanation / Answer
STEP 1
Define salinity and what its measures
The concentration of dissolved salt in a given volume of water is called salinity.
Salinity is the measure of all the salts dissolved in water. Salinity is usually measured in parts per thousand (ppt or )
STEP 2
What is the average salinity of the oceans?
he average ocean salinity is 35ppt
STEP 3
How is chlorinity related to salinity? Explain.
The empirical relationship between salinity and chlorinity, as established by the International Commission, is
[Equation]
The chlorinity that appears in this equation is also a defined quantity and does not represent the actual amount of chlorine in a sample of sea water. Both salinity and chlorinity are always expressed in grams per kilogram of sea water—that is, in parts per thousand, or per mille, for which the symbol ‰ is used.
STEP 4
What happens to local salinity when evaporation rates increase: Rises or Lowers?
Rises.
What happens to local salinity when ice formation rates increase: Rises or Lowers?
Rises
What happens to local salinity when rain increases: Rises or Lowers?
Lowers
What happens to local salinity when river input increases: Rises or Lowers?
Rises
