U/W Archaeology

Underwater archaeology is the study of past human life, behaviors and cultures using the physical remains found in salt or fresh water or buried beneath water-logged sediment. It is most often considered as a branch of maritime archaeology. Due to the difficulties of accessing underwater sites, the application of archaeology to underwater sites emerged from the skills and tools developed by salvagers, and underwater archaeology initially struggled to establish itself as proper archaeological research. Underwater archaeological sites consist of wrecks (shipwrecks or aircraft); the remains of structures created in water (such as crannogs, bridges or harbors); refuse or debris sites where people disposed of their waste, garbage and other items by dumping into the water; or places where people once lived, that have been subsequently covered by water due to rising sea levels or other phenomena.
