200 times more than the land surface
1 1/2 pounds per person
about each human can get about 2.7 pounds of gold
A whole lot! There is a huge quantity of gold is seawater. But it's distributed widely - across all the oceans of all the world - and is incorporated on the atomic level. That makes it very, very hard to separate out. No one has demonstrated that it can be done economically. The concentration of gold in seawater varies from place to place, and ranges between 5 to 50 ppt (about .005 to .05 tonnes (5 to 50 kg) per km3) Given that the volume of all the seas is about 1.37 billion km3 The total amount of gold in all the seas is about 7 to 75 billion kg.
95% of the worlds gold comes from Africa

As PURE sodium, practically none. But a good part of all sodium in the world is in the oceans- in the form of sodium chloride- salt. The total amount would be in the billions of tons. Seawater is about 3.5% salt.
because its the ocean ;D
Well here is one resource that pirates would have loved. There is GOLD in the ocean. In fact there is so much gold in the oceans that everyone in the world would get a fair share of it.

as per findings only 3 % of the total available water in earth is drinkable. 97% is either seawater or non potable
97% seawater, other 3% is freshwater.
On average, seawater in the world's oceans has a salinity of about 3.5% The salinity of human blood is 0.9%. So sea water is roughly 3.5 times as salty as blood.
It is not known how much of the plastic in the world ends up in the ocean. The oceans are becoming more polluted with various types of debris and trash.
