Submarine archaeology is the study of underwater sites and artifacts to understand human history and culture. This field involves exploring shipwrecks, submerged cities, and ancient trade routes, often using advanced technology like sonar and remotely operated vehicles. Researchers in submarine archaeology aim to preserve and document findings, which can include items like ceramics, tools, and shipwrecks. These discoveries provide valuable insights into past societies, their economies, and their interactions with the environment. The work often requires collaboration with marine scientists and conservationists to protect these underwater treasures.
