He was the first to observe that oceans and certain lakes were fed by streams and were therefore constantly receiving more salt.Halley could not test his theories, however, because he needed to know the salt content of the oceans earlier in time to calculate a rate of accumulation (Dalrymple, 2004, p 39). Mellard Reade looked into this process and renamed it chemical denudation.One such failed dating technique is measuring the present salt content of the ocean to create a time scale to determine how long it has existed.This technique was introduced nearly 300 years ago, and it was researched by many prominent scientists for several hundred years until it fell out of favor because of obvious drawbacks in the method.If one cubic foot of sea water is evaporated, it will yield approximately 2.2 pounds of salt (Swensen).The relatively simple method of measuring the salt, along with its abundance is what made this a very appealing dating method to some.If you're seeing this message, it means we're having trouble loading external resources on our website.If you're behind a web filter, please make sure that the domains *.and *.are unblocked.

Science was born from these observations of the natural world.As the water makes its way back to the ocean, it contains a large load of dissolved minerals, a lot of which is salt.What makes the ocean salty is that when water evaporates off of the ocean, it leaves its load of dissolved salt behind and becomes fresh.This, of course, could never be known because no one was around to measure the salinity of the oceans right when they formed.Also, people assumed that the ocean is an eternal reservoir, and when the salt is dumped in the ocean, it stays there permanently.
