Underwater archaeology is the study of human history and prehistory through the excavation and analysis of submerged sites. This field often involves exploring shipwrecks, ancient harbors, and submerged settlements, providing valuable insights into past cultures and civilizations. Techniques such as remote sensing and diving are commonly used to uncover artifacts and structures that have been preserved underwater. The preservation of artifacts in underwater environments can be exceptional due to the lack of oxygen and the stable temperatures found in many bodies of water. Notable discoveries in underwater archaeology include the Titanic and the Antikythera Mechanism, which have both contributed significantly to our understanding of maritime history and technology.
