3D in the Toolbox: An Operational Comparison of Acoustic, Photogrammetric, and Laser Scanning Methodologies Tested at Thunder Bay National Marine Sanctuary in 2016. (2017)

DOCUMENT Citation Only John C. Bright.

The clear, fresh waters of Thunder Bay National Marine Sanctuary offer an ideal testing ground for acoustic and light-based imaging systems. During the 2016 field season, Thunder Bay researchers conducted several field operations to acquire, process, and compare side scan sonar, multibeam sonar, laser-scanner, and photogrammetric data at numerous archaeological shipwreck sites. The resulting analysis provided valuable insights into this array of remote sensing systems in terms of their ability...

The Discovery of the Monterrey Shipwrecks: A Find by Design (2015)

DOCUMENT Citation Only Jack Irion. Frank Cantelas. Amy Borgens. James Delgado. Frederick H Hanselmann. Christopher Horrell. Michael L Brennan.

Roughly 200 years ago, three sailing ships met apparently violent ends in the northern Gulf of Mexico nearly 320 kilometers southeast of Galveston, crashing to the bottom over 1300 meters below. The three ships were very different: one likely a topsail schooner, fast and armed; one a small merchantman, its hold packed with bales of hides; and the third, the largest, empty of cargo, but sheathed in copper and possibly outfitted for a transatlantic voyage. These three vessels were among the...

How the Evolution of Side Scan Sonar and Marine Technology Influenced the Development of Maritime Archaeology (2022)

DOCUMENT Citation Only Vincent Capone. Stephen Nagiewicz. James Delgado. Martin Klein.

This is an abstract from the session entitled "Paper / Report Submission (General Sessions)" , at the 2022 annual meeting of the Society for Historical Archaeology. The British in World War I were the first to recognize the applications of this new sound technology which would later be embraced by other militaries and would eventually find commercial applications mapping the seafloor for natural resources, which drove the technology into more compact, powerful sonar devices, but also add...

Investigation into the Probability of the Existence of Offshore Cultural Resources in the Vicinity of the Proposed Lilco Diffuser Pipeline, Jamesport, Long Island, New York (1977)

DOCUMENT Citation Only Laraine Fletcher. John Vetter.

Multibeam Swath Bathymetry for Underwater Archaeological Investigations (2015)

DOCUMENT Citation Only Daria Merwin. Roger Flood.

Remote sensing technologies have long played an important role in underwater archaeological survey, and among the most recent (and increasingly used) additions to the toolkit is multibeam swath bathymetry, which operates by transmitting sound beams perpendicular to a research vessel's track and then processing the returned sonar data to produce a three-dimensional image of the sea floor. Multibeam survey can be particularly useful in water bodies where conditions are not conducive to other forms...

A new method of rapidly surveying submerged archaeological sites. (2013)

DOCUMENT Citation Only Mark W Holley.

Since 2007, the Underwater Archaeology Program at Northwestern Collage (USA) has been surveying submerged cultural resources both in America and Europe by utilizing sector scanning sonar equipment developed by Kongsberg-Mesotech (Vancouver, Canada). The results of these surveys have been stunning. This paper will explore the catalog of archaeological sites surveyed, methodology of deployment and how this new equipment can contribute to the development of rapid, highly detailed underwater...

Operation D-Day Mapping Expedition (2016)

DOCUMENT Citation Only Joshua A. Daniel. Andy Sherrell. Ralph Wilbanks.

On 6 June 1944, Allied forces launched the largest amphibious assault in history. In the first 24 hours, over 5,000 ships and 13,000 aircraft supported 160,000 Allied troops in their attempt to land on a 50 mile stretch of beach in Normandy. Almost 70 years later, over the course of 27 days in July and August of 2013, a team of archaeologists, hydrographers, remote-sensing operators, divers, and industry representatives surveyed over 511 km2 off beaches in Normandy. The team identified over 350...
