    There is gold in the seawater but it is not enough to get rich,
    Kelly Kenison-Falkner and John Edmond foundd that in the Atlantic and north Pacific there is just 1 gram of gold for every 100 million tonnes of sea water.
    Many people have tried to make money from this. But as analytical techniques have improved the ammount of gold in the oceans is estimated less as before There may indeed be gold in the oceans, but not enough to make anyone rich.
