UNDERWATER ARCHAEOLOGY
[noun]
archaeology practised underwater; the studying of shipwrecks and other human debris found in the ocean. Its acceptance as a formal and valid discipline has been a relatively late development due to a) difficulties involved with accessing and working in underwater sites, b) the application of archaeology to underwater sites only emerged from the skills and tools developed by shipwreck salvagers.
