Podemski, Ph.D., Dean, Graduate School Date ACKNOWLEDGMENTS This thesis was a long series of very fortunate and unforgettable events. It began as a research project where UWF was contracted as a trained archaeological dive crew, and I was lucky enough to be chosen to participate. As a project started by the wonderful archaeologists at BOEM/BSEE, and headed by Dr. Chris Horrell and Melanie Damour, it was prepared and completed with the hard work of Tesla Offshore’s Dr. Amanda Evans and Matt Keith. Without these individuals, I would not have the wonderful experience to share with others as I progress professionally in the field. Of course, the UWF archaeology institute that provided me with countless experience with this, and other adventures, will forever be remembered as the greatest gift which I cannot ever nearly repay. Within the Anthropology Department, I must thank the wonderful men and women who made my experience possible. Dr. Greg Cook brought me into this field, and ultimately gave me experience and practical knowledge on marine archaeology I would be nothing without. Dr. John Bratten was always calmly there to incredibly illuminate my perspective on a situation or concept. Dr. Derek Zumbro kept my wandering mind at bay and gave me the inspiration to pursue battlefield archaeology in ways I had not realized before. Thank you for being omnipresent during this incredible process. I must thank the following people for giving me the love I needed to get through it all: Dave Swanson, Peggy Swanson, Tyler Swanson, Angie Hester, Sophia Antone, Dr. Elizabeth Benchley, Fritz Sharar, Steve and Gale McLin, Bill Neal, Norine Carroll, John Phillips, Cindi Jackson, Rey “Del” Delos Santos, Erin Voisin, Joanne Alexander, and Albert Alexander. “The preoccupation of minds on drawing dividing lines makes it impossible for them to build bridges.” – Dr. Rob Floyd iv TABLE OF CONTENTS ACKNOWLEDGMENTS ............................................................................................................. iv LIST OF TABLES ....................................................................................................................... viii LIST OF FIGURES ....................................................................................................................... ix ABSTRACT ...................................................................................................................................xv CHAPTER I: INTRODUCTION .....................................................................................................1 Research Problem .................................................................................................................1 History and Background Information ..................................................................................2 Data and Methods ................................................................................................................7 Theory ................................................................................................................................11 Significance ........................................................................................................................12 Research Presentation ........................................................................................................14 CHAPTER II: RESEARCH CONTEXT .......................................................................................15 Introduction ........................................................................................................................15 Physical Environment ........................................................................................................17 Historic Context .................................................................................................................22 The Attacks .............................................................................................................31 Theoretical Foundations .....................................................................................................38 CHAPTER III: RESEARCH BACKGROUND ............................................................................47 Previous Investigations ......................................................................................................47 v CHAPTER IV: METHODOLOGY ...............................................................................................66 Introduction ........................................................................................................................66 Historical Research Methodology ......................................................................................67 Archaeological Methods ....................................................................................................70 Post-Processing Methodology ............................................................................................79 CHAPTER V: RESULTS ..............................................................................................................84 Introduction ........................................................................................................................84 Findings ..............................................................................................................................84 Historical Background .......................................................................................................85 Remote-Sensing .................................................................................................................92 Diver Ground-Truthing ....................................................................................................106 The S.S.
