I found on the web that the British ship Madagascar a famous blackwaller of Green and C° who left Melbourne for London in August 1853 whith more than two tons of Australian gold had been found by an international team of researchers. Now they plan to organize an archeological expedition to visit the ship and to save the gold. They don't say of course where the ship is lying and at what depth. See www.shipmadagascar.com if you want to learn more. The loss of the Madagascar is one of the greatest sea mystery of the nineteenth century... Who has more info about this incredible discovery?
