We invite you to revisit British photographer Alastair Miller’s conversation with the accomplished Dr. James Delgado—maritime archaeologist, preservation expert, historian, author, television host and explorer. With more than four decades of experience in underwater exploration, Dr. Delgado often appears on the National Geographic series Drain the Oceans, a program that can be viewed on our ocean ships. During his conversation with Alastair, James shares insights into underwater archaeology while recounting some of the incredible discoveries he has made over the years.
