Having found my first shipwrecks in 1960, I am one of the "founding fathers" of underwater archaeology. My expertise is in the archival research of the history of particular shipwrecks, the search for and exploration of shipwrecks, and the commercial or archaeological salvage of shipwrecks. I have researched tens of thousands of shipwrecks, and made hundreds of discoveries. I work with both for-profit (treasure hunting) groups and nonprofit (educational and research) groups. My work is not related to marine biology or to paleontology.
