Cross Jacques Cousteau with Sherlock Holmes and you get an underwater detective -- or a shipwreck recovery company like Sovereign Exploration Associates International. Through its subsidiaries, the company engages in exploration and recovery of shipwrecks believed to have cargo of historic, archeological, or intrinsic value. Sovereign Exploration Associates International concentrates on shallow-water, in-shore projects. The company has not been profitable, however, and its auditors have questioned whether it will be able to stay in business.
