Marine archaeology is also known as maritime, underwater and nautical archaeology. Each terminology has specific meaning and purpose in which water plays a dominant role. In India it is known as marine archaeology. In maritime or underwater archaeology we study the past activities of human from maritime finds, usually from shipwrecks, sunken ports and settlements. Nautical archaeology is studied and explained as maritime archaeology, specialising in maritime activities and technology of ships, boats and other crafts. Marine archaeology is primarily concerned with exploration, investigation, documentation and recovery of the material remains and physical traces of human activities found on the foreshore and intertidal zones and on the seabed. Over the years the National Institute of Oceanography has undertaken the exploration and excavation of submerged ports and shipwrecks in Indian waters.
