Odyssey Marine find two new shipwrecks in the English Channel

Odyssey, which is battling Spain over the rights to another shipwreck, said it had not identified either of the new sites. The company has been locked in a legal fight with the Spanish government over a shipwreck site it found last year with an estimated $500 million worth of gold and silver coins. Odyssey has code-named the site "Black Swan."

"Both sites lie within the general area of the English Channel but are outside the territorial waters or contiguous zones of any sovereign nation," the Tampa-based company said in a statement.

"The sites both contain cannon and other artifacts which are believed to date from the colonial period."

Potential claimants would be notified if either site can be identified, said Odyssey, adding that it has filed documents in the U.S. federal court in Tampa to protect its salvage rights to the sites.

On Tuesday Odyssey announced a $2 million deal with the Discovery Channel to produce a television series about the company's explorations.
