 is approximately 39 centimetres (15.4 in). The length of the cannon itself is approximately 209 centimetres (82.3 in). Upon retrieval from the ocean, the cannon was encrusted with coral and the salt water had caused rusting and deterioration.

Recovery and conservation

The cannon was found about 70 feet (21.3 m) off the coastal waters of Catalina Island in the Dominican Republic. The cannon was only 10 feet (3 m) below the surface of the water. After it was extracted from the ocean, the cannon was transported to Indiana University to be studied. Initial investigations of the coral

conservation treatments to remove salt from the years of immersion in the ocean. Indiana University will construct a mold of the cannon and make museum-quality, exact reproductions which will be sent back to the Dominican Republic for development of a land-based exhibit on shore by the shipwreck. The cannon will continue to undergo the electrolytic conservation treatment when it arrives at the Children's Museum of Indianapolis for the National Geographic Treasures of the Earth exhibit.Following the discovery, Indiana University has designated the site a "Living Museum in the Sea."

The cannons, anchors, and wreckage from the Cara Merchant were first discovered by a local man who reported what he had found to the Dominican Republic's government. The government made a request to Charles Beeker who has been conducting research in the Dominican Republic for nearly twenty years and his research team at Indiana University to investigate and examine the remains. Beeker, the director of the Office of Underwater Science at Indiana University has been authorized to bring the cannon to his lab for five years for conservation and observation.
