<P> The world's oceans contain gold . Measured concentrations of gold in the Atlantic and Northeast Pacific are 50--150 femtomol / L or 10--30 parts per quadrillion (about 10--30 g / km). In general, gold concentrations for south Atlantic and central Pacific samples are the same (~ 50 femtomol / L) but less certain . Mediterranean deep waters contain slightly higher concentrations of gold (100--150 femtomol / L) attributed to wind - blown dust and / or rivers . At 10 parts per quadrillion the Earth's oceans would hold 15,000 tonnes of gold . These figures are three orders of magnitude less than reported in the literature prior to 1988, indicating contamination problems with the earlier data . </P> <P> A number of people have claimed to be able to economically recover gold from sea water, but they were either mistaken or acted in an intentional deception . Prescott Jernegan ran a gold - from - seawater swindle in the United States in the 1890s, as did an English fraudster in the early 1900s . Fritz Haber did research on the extraction of gold from sea water in an effort to help pay Germany's reparations following World War I. Based on the published values of 2 to 64 ppb of gold in seawater a commercially successful extraction seemed possible . After analysis of 4,000 water samples yielding an average of 0.004 ppb it became clear that extraction would not be possible and he stopped the project . </P> <P> Gold artifacts found at the Nahal Kana cave cemetery dated during the 1980s, showed these to be from within the Chalcolithic, and considered the earliest find from the Levant . Gold artifacts in the Balkans also appear from the 4th millennium BC, such as those found in the Varna Necropolis near Lake Varna in Bulgaria, thought by one source (La Niece 2009) to be the earliest "well - dated" find of gold artifacts . Gold artifacts such as the golden hats and the Nebra disk appeared in Central Europe from the 2nd millennium BC Bronze Age . </P> <P> The oldest known map of a gold mine was drawn in the 19th Dynasty of Ancient Egypt (1320--1200 BC), whereas the first written reference to gold was recorded in the 12th Dynasty around 1900 BC . Egyptian hieroglyphs from as early as 2600 BC describe gold, which King Tushratta of the Mitanni claimed was "more plentiful than dirt" in Egypt . Egypt and especially Nubia had the resources to make them major gold - producing areas for much of history . One of the earliest known maps, known as the Turin Papyrus Map, shows the plan of a gold mine in Nubia together with indications of the local geology . The primitive working methods are described by both Strabo and Diodorus Siculus, and included fire - setting . Large mines were also present across the Red Sea in what is now Saudi Arabia . </P>
