New Directions for Underwater Archaeology in Virginia (2018)
More than two thousand ships have been lost in Virginia waters since the first European explorers ventured here. In addition, countless prehistoric sites and historic piers, wharves and other structures now lie underwater. Yet, except for a few significant exceptions, little emphasis has been placed on locating and studying Virginia’s submerged sites. In a partnership with the Virginia Historic Resources Department, the Archeological Society of Virginia recently formed a Maritime Heritage...
New England’s submerged pre-Contact history: identifying an intact Archaic site in Salem, Massachusetts (2015)
A portion of Salem Harbor in Massachusetts was investigated during a cultural resource management project in 2009/2010. The underwater reconnaissance included a remote sensing survey using a Klein 3.5 kHz sub-bottom profiler. An acoustic basement was recognized at approximately two meters below the sea bed, and was hypothesized to be an organic layer potentially representative of a buried land surface below marine sediment. Vibratory cores were used to ground truth the potential buried land...
New Management Strategies for Submerged Cultural Resources in the U.S. National Park Service. (2015)
With ever increasing stresses to cultural resources in the U.S. National Parks from natural and man-made threats, managers of these resources must evolve and adapt to protect and preserve them all. Some solutions limit or deny access because of the delicate state of the resource or because of the sensitive nature of its history. However, providing access and presenting the past to park visitors in a meaningful way is a primary responsibility of managing places that belong to all Americans. For...
A New Maritime Archaeological Landscape Formation Model (2013)
Underwater archaeology tends to be particularistic focusing on the human activities associated with an event, however; human behavior and its resultant material remains exist on a physical and cultural landscape and cannot be separated from it. Studying known archaeological sites within the landscape reveals patterns of human behavior that can only be identified within that context. The natural environment constrains and informs human behavior and plays an important role in the development of...

Recognizing Geomagnetic Storms in Marine Magnetometer Data: Toward Improved Archaeological Resource Identification Practices (2016)
Strong magnetic field perturbations resulting from Earth-directed solar events can adversely affect marine archaeological survey. The immediate onset of geomagnetic storms and fast compression of the magnetopause create short duration, high amplitude spikes in Earth’s magnetic field that appear similar to signatures of archaeological anomalies. Aggressive processing, analysis, and comparison of single instrument survey and observatory datasets collected during geomagnetic storms prevented...
Recording Historic Shipwrecks at the Speed of Light: An Archaeological Analysis of the ULS-200 Underwater Laser Scanner to Sonar, Video, and Photographic Recording Methodologies (2015)
Since the beginning of underwater archaeology, the effective recording of sites has always been a challenge. This study will compare the ULS-200 underwater laser scanning device to other traditional archaeological recording methods, seek to quantify the average amount of time it takes to conduct a scan underwater and evaluate its accuracy in resolving an image at different turbidities and ranges. Within its ideal range, the expected outcome is that while it will take an equal or longer amount of...
Recording Shipwrecks At The Speed Of Light: Experimental Use Of An Underwater Laser Scanner On The Confederate Ironclad, CSS Georgia (2016)
Since the dawn of underwater archaeology, the ability to record features with a high level of accuracy and detail compared to terrestrial sites has been an extremely difficult prospect. However, according to 2G Robotics, the ULS-200 underwater laser scanner can resolve features on an astounding millimetric scale, but under the most ideal conditions. While this has some very exciting implications for the field of underwater archaeology, the CSS Georgia resides in an extremely challenging and...
A Reflexive Paradigm: Improving Understanding of our Shared Human Heritage (2018)
BOEM’s historic preservation program is based in stewardship, science-informed decisions, and scientific integrity.

Sunken Aircraft of the Battle of Midway (2017)
In June of 2017, the 75th anniversary of the Battle of Midway will occur as archeologists begin the first dedicated project to discover the sunken aircraft at the atoll involved in the battle. Often considered as the turning point of the Pacific Front in World War II, Midway has been difficult to study archaeologically because of the remoteness of the location, and the difficulty in surveying around the treacherous reefs that surround it. Efforts to locate submerged aircraft have been made...
The Tanapag Coronado: a Case Study in Site Formation Processes of Submerged Aircraft Wreck Sites (2018)
The study of submerged aircraft, while not new, is still a relatively unexplored area of maritime archaeology. Receiving even less attention is the study of site formation processes as they apply to submerged aircraft wreck sites—what processes affected the site between the time it crashed and now? These studies are becoming increasingly important, especially for cultural resource managers who are responsible for managing submerged aircraft. This paper summarizes the results of a case study of a...

Tri-Closure: A Quick And Easy Way To Create A Local Coordinate System For Underwater Photogrammetric Recording (2017)
To use 3-D photogrammetric models as scientific data, it is essential for archaeologists to use local coordinate systems to constrain their photogrammetric models to 1:1 scale. This enables archaeologists to take measurements directly from their models. Direct Survey Methods (DSM) are often used to create local coordinate systems; however, DSM often requires several days of diving operations, which may become problematic when recording large or deep-water sites. As a quick alternative method,...
