Underwater archaeology, a branch of maritime archaeology, is the study of past human life, behaviors, and cultures using the physical remains found in bodies of water or buried beneath water-logged sediment. Researchers in this field generally examine the sites of shipwrecks, submerged airplanes, structures created by humans in water bodies, and places where people once lived that have since been flooded or covered by water. How do divers record their findings underwater? Discuss
