Inside the World of Shipwreck Archaeology | Dr. James Delgado

Maritime archaeologist James Delgado joins John Michael Godier to explore how shipwrecks on the ocean floor are rewriting our understanding of history. From luxury liners and forgotten trade ships to war graves and deep-sea wrecks only reachable by modern submersibles, Delgado explains how archaeologists find, map, and interpret these sites, what the Titanic and other iconic wrecks really tell us, and why the deep ocean has become one of the most important archives of human activity on Earth. Along the way he tackles the ethics of disturbing wrecks, the role of cutting-edge technology in underwater exploration, and what unanswered questions still lie in the dark beyond the reach of today’s cameras.The Great Museum of the Sea is Delgado’s sweeping exploration of the world’s oceans as a vast, interconnected archive of human history, where every shipwreck, artifact and submerged landscape becomes a curated exhibit in the planet’s oldest and most expansive museum.https://global.oup.com/academic/product/the-great-museum-of-the-sea-978019778075600:00 Introduction00:18 Who is James P.
