The Ocean Explorer team conducted between June 6–19, 2011 together with Franskabolaget.com a search expedition to find more of the sunken treasures of the Sea of Bothnia (northern Baltic Sea). The treasures consists of alcoholic beverages such as Champagne, Wine and Cognac laying in the holds of small Swedish merchant ships sunk by the Germans during the first world war.
The most famous wreck so far is with out doubt the small ketch "Jönköping" which was sunk on the 3 November 1916 by the German Uboat U 22 with 3000 bottles of Heidsieck & Co MONOPOLE Gôut Américain champagne from 1907, and 67 barrels of Bisquite & Duboché Cognac, each barrel containing 600 litres in her holds. Some of the champagne bottles has been sold for as much as EUR 20 000 per bottle.
This years first search/salvage expedition was granted with for the season terrible weather which did the search nearly impossible and is a reason why the Ocean Explorer team will continue the search for the "fluid gold" later during this summer.
However, on the 19 June a very strange anomaly was found during a sonar survey of the sea floor. Peter Lindberg, the initiator of the expeditions, says that he has never seen anything like it . . ..
