AUVs using side-scan sonar imaged a cylindrical object on the seafloor that looks similar to a cannon. On closer inspection it was found not to have the characteristic features which are evident on a cannon from the H.M.S. Cerberus Site. Both the Cerberus and Lark were burned and sunk to avoid capture, and the Lark’s onboard supply of gunpowder exploded, destroying the frigate and creating a large debris field. This is an example of why it’s important for archaeologists to closely examine each object to establish their context in time and space in order to interpret past events.
