damage ships. Photographs of damaged sites underscore his findings. Brennan feels that fishing gear is one of the greatest threats to underwater cultural heritage. Martin Gibbs and Brad Duncan’s “Cultural Site Formation Processes Affecting Shipwrecks and Shipping Mishap Sites” considers salvage as a site formation process. They note that researchers should note the distinction between “pre-impact actions” and “Crisis,” “Survivor,” “Systematic,” and “Opportunistic” salvage and the purposeful abandonment of vessels. Part III focuses on site formation and heritage management. Ian Oxley describes how English Heritage uses wreck site information and site formation theory to develop policies for historic marine environments. Standardization in reporting was imperative to the creation of its National Heritage Protection Plan, which determines priorities based on research and creates a framework for management. The “DeepWrecks Project” in the Gulf of Mexico ends the book. Daniel Warren’s “Acoustic Positioning and Site Formation on Deep-Water World War II Shipwrecks in the Gulf of Mexico” demonstrates how acoustic positioning data are important to determining site distributions. Robert Church’s “The U-166 and Robert E. Lee Battlefield: The Equation of Site Distribution” builds on Warren’s data to understand the battle and the sinking of both vessels. From this methodology, sites may be more clearly delineated and protected. Matthew Keith ends noting that site formation studies provide information for archaeologists and heritage managers. The multidisciplinary approach demonstrates the complexity of underwater research and underscores the need for specialization. Keith has brought together an informative volume. The discussions are nuanced and sophisticated. The target audiences of Submerged Shipwrecks are advanced undergraduates, graduate students, and professionals. All will appreciate this fine book.
