A ship that sank off the coast of California decades ago was recently reconstructed in detail. The 3D digital model even included hundreds of sponges (海绵动物) that have gathered on the ship's surface since it sank.

Named American Heritage, the supply ship sank in Santa Monica Bay on May 4, 1995, and for decades its exact location was unknown. Researchers with the Monterey Bay Aquarium Research Institute (MBARI) spotted a strange shape in that area in 2008. But it wasn't until May 2018 that MBARI scientists identified its exact location and mapped the site in detail, showing what appeared to be a shipwreck (失事船只).

Even then, the identity of the shipwreck was uncertain. Yet another MBARI team revisited the location to do further exploration. They sent remotely operated vehicles (ROVs) and took photos of the damaged ship. Though it was covered with deep-sea sponges and other animals, the scientists were able to spot letters spelling out its name, confirming that the shipwreck was American Heritage.

As one of the MBARI scientists who found American Heritage, chief ROV pilot Knute Brekke had worked on the ship before. And he was on duty with the diving company American Pacific Marine — the owner of American Heritage — that night the ship began taking in water and eventually sank.

MBARI spokesperson Kim Fulton-Bennett said to Live Science about the discovery, "The model is not complete, as floating ropes and poor visibility kept the pilots from getting too close to the wreck. But the 3D reconstruction is detailed enough to show that American Heritage is now home to thousands of sponges. Shipwrecks often turn into the shelter for diverse communities of ocean life. "
