Maritime archaeology is the study of human interaction with the sea, lakes, and rivers through the recovery and analysis of submerged artifacts and structures. This field explores shipwrecks, harbors, and coastal settlements to understand historical trade routes, naval warfare, and cultural exchanges. Researchers in maritime archaeology use various techniques, including underwater excavation and remote sensing, to locate and document sites. Notable discoveries include ancient shipwrecks, sunken cities, and maritime trade routes, which provide valuable insights into past societies and their relationship with water.
