TheDenbighProject: initial observations on a Civil War blockade-runner and its wreck-site

The role of scour in shipwreck site formation processes and the preservation of wreck-associated scour signatures in the sedimentary record – evidence from seabed and sub-surface data

“…In archaeological investigations, scour signatures are reported from nearshore shallow-water submerged wreck sites [1,6,22,24,27,42,43,48,51] to deep-water archaeological sites on the continental shelf [2,3,19,44]. Scour signatures are reported from intact and scattered wreck sites [1,6,22,24,27,42,43,48,51] and from individual artefacts and artefact scatters [2,3,19] emanating from wrecks.…”

“…Scour signatures are reported from intact and scattered wreck sites [1,6,22,24,27,42,43,48,51] and from individual artefacts and artefact scatters [2,3,19] emanating from wrecks. Although frequently reported and often described in a qualitative (or at best semi-quantitative) manner, there is a distinct paucity of quantitative discussion in the archaeological literature on the role of scour in shipwreck site formation processes.…”

The Denbigh Project: test excavations at the wreck of an American Civil War blockade-runner

“…Historical evidence for the Denbigh was presented in detail in the ® rst preliminary report (Arnold et al 1999). She was an iron-hulled, side-wheel steamship 182ft (55.5m) long, displacing 258 tons, built by Laird, Sons & Co. of Birkenhead (Merseyside, England).…”

“…A report published on the ® rst ® eld season in 1998 covers the pre-disturbance survey, including extensive remote-sensing, as well as the ship's history as it was then known (Arnold et al 1999; see also the project website, http: //nautarch.tamu.edu/projects/ denbigh/denbigh.html). The present paper is the second in a projected series of progress reports, and provides updated ® ndings on the ship's history as well as a summary of the results of the 1999 test-excavation phase of the project.…”

Comparison of the maritime Sites and Monuments Record with side‐scan sonar and diver surveys: A case study from Rathlin Island, Ireland

“…Therefore, the only satisfactory method presently available for quantifying marine archaeogeophysical data is to physically ground-truth any ambiguous reflectors, either through diver or remotely operated vehicle (ROV) investigations. With the increase in predevelopment and researchorientated geophysical surveys (Quinn et al, 1997bArnold et al, 1999;Momber and Geen, 2000;Simms and Albertson, 2000), combined with initiatives to substantiate SMRs, a rapid and accurate method for ground-truthing geophysical data is essential. This paper details the methodology and results of such an exercise VOL.…”
