The water in the ocean actually holds gold! The gold in the ocean is so mixed in that the concentration is very low. There is about only 1 gram of gold for every 100 million metric tons of ocean water. That gold has dissolved in that water over thousands of years. Dissolution is when a substance gets broken down into smaller and smaller pieces until it mixes with the liquid it is in. There is also undissolved gold in or on the seafloor. Those gold deposits are all covered with dense layers of rock, which makes that gold really hard to get. People have not found a way to extract that gold yet. That is how there is about 9 pounds of gold in the entire world’s oceans!
