A new expedition to explore the Titanic wreck has been proposed, but the United States is opposing it. The U.S. argues that the proposed plan doesn't comply with international standards for the treatment of underwater cultural heritage sites. The expedition is intended to document the shipwreck's condition and create a 3D model for future preservation efforts. However, the U.S. believes that it could potentially disturb the site and lead to the loss of valuable historical information. The debate highlights the challenges of balancing exploration and preservation when it comes to iconic underwater archaeological sites like the Titanic.
