Answer 1

Atlantic, Gulf of California or the Sea of Cortez (langosta) ?

OKAY, no help with that clarification so:

The average ocean salinity is 35 ppt
Salinity 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.
