Anybody that has been in the ocean can tell you it is salty by the simple fact that you can taste the salt. Which leads to the question of just how much salt is there in the ocean. The answer to that question is that there are around 35 parts of salt per thousand in seawater.

This means that around 3.5% of seawater is made from dissolved salts. If you could extract the salt and weigh it, the salt from a cubic mile of salt water would weigh approximately 120 million tons. The technical term for the ratio of dissolved salt in water is salinity.
