"One of the last remaining and persistent mysteries of the Pearl Harbor attack is that of the Japanese Midget Submarines. It is a fascinating story of innovation, courage, secrets, and failed expectations. And it is not only a story of the morning hours of December 7, but of the years before to develop these weapons and the years after, where they were deployed in the great Pacific War and how they fared as weapons of war." These words by Daniel J. Basta, Director of the Office of National Marine Sanctuaries, from the foreword of this manuscript, capture both the essence and the impact of this work, assembled by James P. Delgado and his coauthors. Th e authors have combed the records of the Imperial Japanese Navy and the recollections of its veterans as well as US Department of Defense archives. They have logged hours of direct observation and research on the mini-subs in their final resting places, in some cases more than 1,000 feet below the surface of the Pacific. And in the end, they have woven a tapestry of scholarship, historical sleuthing, scientific insight, and good storytelling that will enthrall specialists and history buff s alike.

In The Origins of the Lost Fleet of the Mongol Empire, Randall Sasaki provides a starting point for understanding the technology of the failed Mongol invasion of Japan in 1281 CE, as well as the history of shipbuilding in East Asia. He has created a timber category database, analyzed methods of joinery, and studied contemporary approaches to shipbuilding in order to ascertain the origins and types of vessels that composed the Mongol fleet. Although no conclusive statements can be made regarding the origins of the vessels, it appears that historical documents and archaeological evidence correspond well to each other, and that many of the remains analyzed were from smaller vessels built in China's Yangtze River Valley. Large, V-shaped cargo ships and the Korean vessels probably represent a small portion of the timbers raised at the Takashima shipwreck site.

Entranced by history and myth, captivated by the wonders of nature, Damian Le Bas explores the meaning we find in sunken ruins around the world.

Thousands of years ago, an island off the Straits of Gibraltar went to war with ancient Athens. The battle was lost, and an earthquake cleaved the land in two. Overnight the island sank beneath the waves – or so legend tells.

As a young boy, Damian Le Bas was captivated by the story of the lost city of Atlantis. As an adult, he dreams of diving to discover its ruins. After the death of his father, torn between his lifelong desire and the taboo his Romany culture places on the ocean, he comes by chance across a dive shop. He can’t help but go in.

Under the waves, Damian enters a breathtaking world. As he masters the skills of this exhilarating sport, diving with seals in the Farne Islands, exploring submerged Roman ruins in Naples and mapping the sunken city of Port Royal in Jamaica, he is entranced anew, by wonders both man-made and natural.

Plato's writings on Atlantis were a parable about the hubris of humankind; in witnessing our effects on oceans and ocean communities, Damian finds echoes of this in the modern world.

A spellbinding love letter to diving, The Drowned Places is also a profound examination of the power that myth has over us, and what happens when it crosses over into reality.
