TAMPA, Fla. AP – Florida deep-sea explorers have gone on the offensive in a legal dispute with the Spanish government over a treasure-laden shipwreck, asking a federal judge to protect the secret locations of possible wreck sites and demanding damages for the nation’s “appalling” interference with its operations.

Odyssey Marine Exploration wants protective orders to maintain the confidentiality of three shipwreck sites it has located and compensation for Spain’s “illegal” seizure and interference with its ships working out of the British port of Gibraltar, according to documents filed late Monday in federal court in Tampa.
