TAMPA, Fla. -- A ship belonging to Florida deep-sea explorers has left Spanish waters, ending the latest round in an increasingly nasty dispute with that nation's government over the rights to a vast sunken treasure.
Odyssey Marine Exploration's ship chugged out of Spanish waters Thursday, a day after Spanish authorities released the vessel. They seized the ship July 12 after it left British-controlled Gibraltar to search the vessel for clues as to the origins of an estimated $500 million in silver coins and other artifacts salvaged from a still undisclosed shipwreck.
Some experts believe Odyssey found the wreck of the Merchant Royal, a British ship loaded with tons of Spanish coins that sank off the southwestern tip of England in 1641. The company received exclusive salvage rights to a wreck site in the area where the Merchant Royal is believed to have gone down.
