Regulating Scientific Diving and Underwater Archaeology: legal and historical considerations

The regulation of scientific and archaeological diving is complex but it is essential that underwater archaeologists are familiar with the requirements placed on them by legal systems. This paper outlines the history and development of current legal systems in four jurisdictions: the UK, USA, EU and Australia. This historical and legal approach informs key discussions facing maritime archaeologists; reference is made to training requirements, safety records and the question of who should be allowed to participate and who should be excluded from archaeological diving.     

广东“南澳Ⅰ号”明代沉船出水铜器腐蚀产物分析

由于海水环境中含有大量氯化物,海洋出水铜器在出水前已发生腐蚀,生成铜的氧化物及氯化物等。本文以广东"南澳Ⅰ号"明代沉船出水的22件铜器残片为研究对象,运用X-射线荧光仪(XRF)、X-射线衍射仪(XRD)和扫描电镜与能谱仪(SEM-EDS)等分析其腐蚀产物和矿物组成,结果表明腐蚀产物主要为铜的碱式氯化物,如Cu2(OH)3Cl和Cu(OH)Cl等,与国外已有研究成果类似,但Cu(OH)Cl在国外海洋出水铜器腐蚀产物中并不常见。     

New Evidence for the Submerged Ancient Harbour Structures at Tolmetha and Leptis Magna,Libya

Surveys carried out in 2009, during a project for the creation of three underwater archaeological parks in Libya, have allowed archaeologists both to analyse already known ancient structures and to discover new evidence about the harbour areas of the ancient cities of Tolmetha and Leptis Magna. © 2012 The Author     

The role of the Italian Central Institute of Restoration in the field of underwater archaeology

In 1987, given the importance and complexity of the correct recovery and conservation procedures for underwater archaeological finds, an Underwater Archaeological Operations Unit was set up within the Italian Central Institute for Restoration. This Unit is made up of archaeologists, conservators, biologists and chemists, all of whom are underwater experts. It provides consultancy services and scientific and technical assistance for problems relating to the recovery, conservation, protection, and restoration of underwater archaeological heritage at the request of the Archaeological Superintendents. Great attention is paid to the professional training of underwater conservators. Specialized courses in the conservation of materials of underwater provenance are organized as part of its programme. This paper illustrates some of the main initiatives both in the restoration of archaeological objects and in training, in which the Institute has been involved, since the Underwater Unit was created.     

Education in Maritime Archaeology: The Egyptian Case Study

The investigation of archaeological sites of maritime nature started in Egypt more than a century ago, with the discovery of the Dahshur boats (Haldane 1998) and the ancient harbour of Pharos (Jondet 1912); however, education in maritime and underwater archaeology in Egypt is still in its infancy. This paper will look at the development of maritime archaeology in Egypt as a scientific discipline and the progress achieved to date in providing Egyptian archaeologists with education and training in aspects of maritime archaeology and underwater cultural heritage.     

The HMS Swift shipwreck: The development of underwater heritage protection in Argentina

Abstract

The aim of this article is to evaluate, with a critical perspective, the legal framework for heritage protection in Argentina, viewing it within an international context and focusing on the HMS Swift shipwreck – sunk in Puerto Deseado (Santa Cruz province) in 1770 – as a case study. Moreover, some initial proposals for a management plan are presented as a first step in thinking about the challenges of preserving underwater sites in Argentinian Patagonia.

Through this analysis some interesting points are outlined, including the reasons that make the Swift shipwreck a leading case in Argentina. It is the first interdisciplinary underwater archaeology project in the country comprising archaeologists who are also divers; it is supported by national authorities; and it is the first project of its kind to give underwater archaeologists experience in dealing with archaeological research and preservation in an environment of multiple conflicting interests.

The international relevance of the Swift case relies on the nature of underwater cultural heritage as an international resource. The project's history is located in an international setting, derived from ihternational trade and communication, in which many ships and their contents have been lost far from their origin or destination. At a national level the Swift is a wreck with significant historical and cultural value. It is in a unique state of preservation and its location near to the shore makes it highly accessible. Locally,HMS Swift will be relevant when Puerto Deseado's community starts to recognise it as a significant part of their own heritage and local people become involved in the preservation of the wreck.     

More than Meets the Eyes?: Archaeology Under Water,Technology, and Interpretation

Abstract

Archaeology has had a long and interesting relationship with technology. Technology has arguably allowed us to move from antiquarian interest to the robust academic institution that we now are. The importance that technology plays within archaeology is perhaps best exemplified within the increasingly popular/populist 'sub-discipline' of underwater archaeology. After all, contemporary underwater archaeology could not exist if it was not for the invention SCUBA. Alongside the 'day-to-day' use of technology there is also a rush to latch on contemporary technologies within the sub-discipline. The reasons for this are examined within this work, however, what is argued to be more important is the implications this has had on our discipline.

This paper examines these implications on and as part of underwater archaeology. The impact of its use on interpretive thinking within the sub-discipline are analyzed by assessing the very nature of theoretical thinking within our work. This paper raises the difficult and perhaps controversial question — are underwater archaeologists merely substituting technology for theory and as such offering, admittedly impressive, complex and sound scientific computer models as interpretation, rather than the data that they really are?     

Local Resources,Global Heritage: An Introduction to the 2001 UNESCO Convention on the Protection of the Underwater Cultural Heritage

On January 2, 2009, the 2001 UNESCO Convention on the Protection of the Underwater Cultural Heritage entered into force, setting an international precedent for the protection and preservation of underwater archaeological resources and providing guidelines for site management and responsible investigation. Historically, submerged cultural resources, particularly shipwrecks, have been exploited primarily for their potential monetary value. Over the last 50 years archaeologists have challenged this perception, demonstrating the cultural and scientific value of submerged cultural resources.     

A Colonial Shipwreck in Saipan,Northern Mariana Islands

Previous underwater cultural heritage investigations conducted in the western Pacific's Northern Mariana Islands largely focused on the submerged World War Two remains, despite the islands’ rich colonial history. The island chain was the setting of numerous historical occupations including indigenous Chamorro populations, Spain, Germany, Japan and the United States, all of which created a lasting maritime heritage legacy on land and under water. This paper presents the first colonial shipwreck investigation to be undertaken by archaeologists and fills a gap in our history and knowledge of the Mariana Islands’ pre‐World War Two era.     

An Early Bronze Age Logboat from Degersee, Southern Germany

In 2004 the remains of a logboat were discovered in Degersee, a small lake near Lake Constance, southern Germany. Dating to the beginning of the 2nd millennium BC, it is an important find from a period with scarce archaeological evidence and only a few previously-known logboats. The vessel was situated in lake sediment and documented in situ . Our investigations can be linked to palaeo-environmental studies carried out at Degersee and adjacent lakes, and to palaeo-climatic research in the northern Alpine region. After investigation by underwater archaeologists the boat was moved to a sheltered place in deeper water.

Rigorous Reasoning, Reflexive Research and the Space for 'Alternative Archaeologies'. Questions for Maritime Archaeological Heritage Management.

As England's heritage policy is shaped around us, it is vital that there is debate, and some consensus, among the maritime archaeological community on core management questions. These include approaches to degrading underwater sites, how to deal with shipwrecks threatened by development, and crucially, who should be driving these decisions. This paper argues that there is a need for self-critical analysis of the meaning of 'heritage'. It problematises the notion of professional archaeologists as 'guardians of the archaeological record' and the conception of 'heritage' formed without reference to ideas of the past being a product of the present and, therefore, the potential for the production of multiple pasts.

Demonstration Survey of Prehistoric Reef‐Net Sites with Sidescan Sonar,near Becher Bay,British Columbia,Canada

Sidescan sonar was deployed in challenging shallow‐water conditions to demonstrate the potential for recording anchor‐stones left on the sea‐bed from prehistoric fishing operations. In less than three hours the survey successfully mapped a reef‐net site originally recorded in 1985 by diving archaeologists over many hours. In addition, 8 km of coastline were surveyed, resulting in the discovery and recording of one new underwater reef‐net site. Our understanding of evolving subsistence practices of the Straits Salish, for whom reef‐net fishing was a critical activity, may be enhanced by this survey method which provides cost‐effective access to data not otherwise being recorded. © 2011 The Authors     

UNESCO, URI, and Archaeology in the Deep Blue Sea: Archaeological Ethics and Archaeological Oceanography

Multiple groups have interests that intersect within the field of deep submergence (beyond the 50 meter range of SCUBA) archaeology. These groups?? differing priorities present challenges for interdisciplinary collaboration, particularly as there are no established guidelines for best practices in such scenarios. Associating the term ??archaeology?? with projects directed at underwater cultural heritage that are guided by archaeologists poses a real risk to that heritage. Recognizing that the relevant professional organizations, local laws, and conventions currently have little ability to protect pieces of cultural heritage across disciplines and international boundaries, the authors propose institution-specific mechanisms, called Archaeology Review Boards, guided by local and international laws and conventions concerning cultural heritage, as the best means to provide oversight for academically centered archaeological activities at the local level.     

Archaeology’s quest for a seat at the high table of anthropology

Between 1900 and 1970, American archaeologists perceived themselves as second-class anthropologists because the archaeological record suggested little not already known ethnographically, archaeology served anthropology by testing ethnologically derived models of cultural evolution, the archaeological record was ethnologically incomplete as a result of poor preservation, and archaeologists used but did not write anthropological theory. Ethnologists of the period agreed with these points and regularly reminded archaeologists of their limited role in anthropology. A few archaeologists claimed in the 1950s that archaeology could contribute to anthropological theory but they were ignored. The claim was reiterated by new archaeologists of the 1960s, and by the 1970s worries about the poor preservation of the archaeological record had softened. However, most archaeologists after 1970 (and before 1990) used anthropological theory and did not write new theory on the basis of archaeological data. The root cause of American archaeology’s ninety-year absence from anthropology’s high table of theory seems to be the discipline-wide retention of the ninety-year old belief that archaeology is prehistoric ethnology and the (unnecessary and constraining) corollary that archaeologists must use anthropological theory to explain the archaeological record.     

As the Sand Settles: Education and Archaeological Tourism on Underwater Cultural Heritage

Underwater cultural heritage sites draw thousands of diving tourists lured by the excitement of shipwrecks and the beauty of the marine environment. Through scientific research and interpretation, archaeologists have the opportunity to educate these visitors about the history of the sites and, perhaps more importantly, about the need for preservation. Effective interpretation leads to appreciation of underwater cultural heritage sites as links to our past, rather than simply as mines of ‘treasure’ to be salvaged for personal gain or sites of interest to be consumed by tourists. This paper describes a selection of interpreted maritime sites from the continental US (with specific reference to Florida), the Caribbean, and the Pacific to show how archaeological tourism, specifically shipwreck preserves and heritage trails, can begin to change mindsets, engage emotions, and inform visitors. It also discusses ways in which we can improve upon assessment, monitoring, and long-term preservation strategies after the trails are created and the sand has settled.     

The Western Ledge Reef wreck: a preliminary report on investigation of the remains of a 16th-century shipwreck in Bermuda

In September 1988 archaeologists and students from the Program in Maritime History and Underwater Research at East Carolina University (PMHUR) identified the remains of an early shipwreck during a survey of the Western Ledge Reefs carried out for the Bermuda Maritime Museum (BMM). Structural material exposed at the wreck site proved to be a section of lower hull containing the keel, hull planking, frames, and a portion of the keelson that included a mast-step. In order to recover the archaeological record preserved at the site, the BMM applied for, and received, a licence from the Receiver of Wreck. As work at the site intensified, a prior claim to the wreck was discovered. Discovery of that claim ultimately led to a co-operative agreement between Brian Malpas, Donald Canton and the BMM that permitted on-site investigation to continue. During 1989 and 1990, the site was excavated by the Museum's underwater archaeological staff, the staffand students of the PMHUR and volunteers. In 1990, a comprehensive in situ map of the hull remains was completed and in accordance with the terms of an agreement between Malpas and Canton and the BMM, a team of archaeologists, students and volunteers raised the remains of the Western Ledge shipwreck in August 1991. Each recovered element of the wreck was transported to storage facilities at the museum and catalogued, cleaned, recorded and documented using techniques developed to record the Red Bay galleon. That work was completed in the autumn of 1991 and on 31st October 1991 the wreck structure was donated to the museum for study and possible display.     

Refining the identification of native American pipestone quarries in the midcontinental United States

Midcontinental pipestone quarries in Missouri, Minnesota, Wisconsin, Illinois, Ohio, and Kansas were utilized by a number of native cultures from 5000 YRBP through historic times. Except for Gunderson’s pioneering work on catlinite, the mineralogy of these sources was poorly understood until recently. For fifteen years, a University of Illinois team of archaeologists and geologists has used well-established mineralogical methods (X-ray diffraction [XRD] and reflectance near-infrared spectroscopy [NIS]) to identify and characterize nine pipestone quarries and match sources with archaeological artifacts from major Hopewell and Mississippian culture sites. NIS analyses of raw materials from nine major pipestone quarries show distinct mineralogical differences between sources but relatively uniform composition within each source. The major distinguishing minerals estimated from NIS spectra match very well with earlier results from XRD and inductively-coupled plasma (ICP) analyses. Results demonstrate that NIS is a reliable non-destructive technique for discriminating between midcontinental pipestones and for sourcing pipestone artifacts.     

考古发掘与考古发现

考古发现和考古学理论方法是考古学赖以进步的两条腿。考古发现不断刷新考古学家的视野并为考古学研究的深入提供新的资料,考古学理论方法使考古学的眼睛更加明亮,分析和思考更具有科学的力量。理论方法让考古学家对考古发现有更深入的认识,考古发现同时也推动综合研究和理论方法的进步。此外,考古发现往往会引起社会的关注,考古发现和考古学知识的普及可以为考古学的进步提供良好的社会环境,从而对考古学的发展产生强大的推动力量。考古学的持续发展要求考古学家必须正确处理考古发现、考古学自身理论方法的完善以及考古学与化遗产保护、公众知识状况和社会需求的关系。     

Confessions of an Archaeological Tour Guide

This article examines the contradictions, responsibilities and opportunities that inhere when the authenticity of the tourist experience results at least in part from having an archaeologist guide. It is argued that archaeologists are always participants in tourism, through the visions of the past they offer in even the most scholarly of papers, that make their way to tourists and tour guides through a wealth of secondary literature. It is argued that, even if most are not aware of it, archaeologists are engaged with the cultural heritage industry and it would be irresponsible to try to step aside. It is argued that archaeologists should take responsible action in light of the undeniable influence of archaeologists in defining the routes and meanings of site tours.     

American digger and archaeology (Respond to this article at http://www.therai.org.uk/at/debate)

This editorial reflects on the nature of public archaeology. It looks at the relationship archaeologists have with popular TV, focusing in particular on the new series American digger by Spike TV, and Diggers by National Geographic, and reflects on the relationship archaeologists have with amateurs using metal detectors to uncover treasures.
