Billions of ounces of gold lie on the ocean floor, washed down by rivers over millions of years. Offshore suction dredging is the most dangerous and rewarding method of recovery in existence.

In the Bering Sea off Nome, Alaska, dredgers use massive 10-inch suction houses on ice-strengthened barges to suck gold-bearing glacial till from the sea floor.
Target Depth:
Most operations occur in 15 to 40 feet of water. Divers face extreme cold and zero visibility.
Not just Alaska. The coasts of Namibia and South Africa produce massive amounts of "Marine Diamonds," often associated with high-purity gold deposits in ancient submerged riverbeds.
The ocean is a dynamic environment. Unlike river dredging, you face tides, swells, and unpredictable weather systems. **Equipment failure offshore is often a fatality.** Professional operations require redundancy in breathing systems and hull integrity.
Ocean swells cause the suction hose to "heave," potentially crushing a diver against the sea floor.
Sucking the sea floor creates a "blackout" cloud. Divers work primarily by touch.
Decompression sickness (The Bends) is a constant threat for deep-water divers.
Strategic weight valuation. Calculate the spot yield of your discovery and bridge the target gap to a physical ounce.
"The gap to a full ounce is only 30.10 grams..."
