This article reports the results of using a sector‐scan sonar to record diverse submerged archaeological sites in shallow and deep water. The Kongsberg MS1000 sector‐scan sonar was developed for commercial applications, typically underwater inspections of bridges, dams, ports and harbours. The ability of the device to rapidly generate high‐quality, geometrically accurate scans of submerged features, coupled with its ease of use and deployment make it a potentially important, yet largely overlooked, tool for survey and management of underwater archaeological sites. As one of several technologies available, the paper examines its advantages and limitations, and considers, through case studies, under which conditions it is most effectively deployed.  相似文献

Maritime investigations along the Northern Adriatic coast have traditionally focused on the Roman and later archaeology. However, studies of post-glacial sea-level change and shoreline displacement suggest there is significant potential for the discovery of sites close inshore dating back to the early- to mid-Holocene, c .9000 BC onwards. A feasibility study for the investigation of submerged sites along the coast of Slovenia was undertaken in 2005. Here we describe the project rationale and research design, the survey and recording methods used, the logistical problems encountered, the results obtained (regardless of age), and the prospects for future research in the region.

Two Late Roman Wrecks from Southern Cyprus   总被引:1,自引:0,他引:1  
Two scattered Late Roman shipwrecks were discovered in the course of underwater survey at Cape Zevgari and Avdimou Bay off the southern coast of Cyprus. Each was transporting a primary cargo contained in amphoras, in one case either local or from nearby Syria or Cilicia, and the other certainly from the southern Levantine coast. The two wrecks offer insight into regional maritime exchange networks within the socio-economic context of late antique commerce around the island. Both sites also contribute to a greater understanding of the utility of systematic shallow-water survey to shipwreck archaeology.

This article describes fieldwork undertaken in 1972 at the harbour of the Hellenistic city of Ptolemais at Tolmeita in Cyrenaica, Libya. This survey has shown that the city possessed a sophisticated Hellenistic harbour installation, now submerged by some 2 m. It consisted of a small fishing harbour and a larger commercial harbour protected by extensive stone breakwaters built around two offshore islands. Between the harbours, remains were found under water of an extensive block‐built quay connected to one island, where there was a system of submerged rock‐cut tanks. These are interpreted as the foundations of a fish‐processing factory. Changes in sea‐level are also discussed.  相似文献

The aim of this article is to introduce to the international bibliography a report submitted to the Archaeological Society of Athens by Ephor Christos Tsoundas in 1885 summarizing what was to be the first state-sponsored underwater archaeological survey in Greece, and potentially the first such survey in general. A brief introduction is followed by a translation of the decision to conduct the survey, as well as of the final report submitted the following year. The fascinating insight which Tsoundas demonstrates in the report allows us a glimpse of the beginnings of underwater archaeology at the worthy site of the Battle of Salamis.

Since November 2007 an underwater project has been carried out by the Archaeological Research Unit of the University of Cyprus, in collaboration with the Department of Antiquities, at a shipwreck on the south coast, 14 miles south‐west of Larnaca. Its cargo consists mainly of Chian amphoras and has been provisionally dated to the 3rd quarter of the 4th century BC. The good state of preservation of the site gives an opportunity for studying amphora stowage and the wreck‐formation process. Moreover, it can shed new light on sea‐routes and trade between Cyprus and the Aegean during the late Classical period. © 2010 The Author  相似文献

By combining underwater survey with formal and compositional study of ceramics, recent work at Burgaz (south‐west Turkey) reveals a late 6th‐ or 7th‐century assemblage of wine and perhaps other agricultural products carried in LR1 and LR2‐related amphoras. Representing various south‐east Aegean and likely Cilician producers, the mixed cargo aboard this probable shipwreck offers insights into the complex dynamics of seaborne distribution at the end of Antiquity. This brief study also underscores the need for documentation in underwater survey of amphora forms and fabrics, particularly those from a period characterized by intensified and diversified production of supra‐regional ceramic types.  相似文献

Because it is often difficult to preserve fragile relics in situ at underwater cultural heritage sites, it is sometimes necessary for relics to be extracted and moved to a controlled environment on land for protection and study. This paper discusses the feasibility of using the volatile organic compound veratraldehyde as a temporary consolidant for underwater fragile relics extraction. The results show that different materials (iron, tile, sand, wood) under water can be bonded together and extracted when using veratraldehyde. The fact that veratraldehyde is difficult to spread on the surface of underwater objects is a problem that can be solved by adding a layer of strong hydrophobic polypropylene (PP) fibres onto the object, serving as a ‘package' for the relics. Under laboratory conditions, we used veratraldehyde and PP fibres to extract broken tiles from underwater sand onto an exhibition stand. The broken tiles, in both condition and distribution, were safely and completely retained as the veratraldehyde was slowly removed by the soaking process. This work fills a gap in knowledge about temporary consolidant materials in underwater archaeology, and provides a new method for extracting underwater fragile cultural relics without damaging them.  相似文献

Abstract

Florida waters are home to the remains of such diverse watercraft as galleons, freighters, sailing yachts, steamboats, and prehistoric canoes. Managing these resources, especially regarding questions of access versus preservation, can be a daunting task. Florida’s Underwater Archaeological Preserves programme is an experiment in public participation to further both the awareness and the preservation of submerged heritage through site conservation and interpretation, incorporating various stakeholders during each step in the process. The logic in Florida’s Preserves programme is that an involved public given free access to a shipwreck site can be an ingredient for, instead of a hindrance to, preservation. Although one of several programmes worldwide, the concept that sets Florida’s Underwater Archaeological Preserves programme apart is its use of public involvement to promote education that fosters attitudes of conservation and preservation. If the public feels a share as stakeholders in the preservation of their maritime heritage, then submerged cultural resources will be more effectively protected.  相似文献

Abstract

The 2003 and 2004 surveys at the Purrón Dam Complex (PDC) demonstrate the value of resurveying previously studied areas. Additional habitation sites, water management features, a cave with pictographs, and a major canal were discovered, increasing the number of recorded sites from eight to 57. From this survey, the collected ceramics and a synthesis of 12 chronometric dates suggest that water management was initiated in the complex by Early Formative times at ca. 1050–1100 b.c., and that the Purrón Dam was completed by the Middle Formative Period (ca. 650–450 b.c.), when settlements were small and decentralized. This challenges previous interpretations that place the PDC florescence during the Early Classic Period (ca. 150 b.c.a.d.250), a period with larger aggregated communities displaying social ranking. The results of our survey have implications for understanding the links between political complexity and agricultural intensification, and support recent ethnographic and archaeological research discrediting the argument that increasing social complexity necessarily leads to the construction of large water management systems.  相似文献

Abundant archaeological evidence and specific geomorphologic features make the upper course of the Ljubljanica River running through Ljubljana Moor (Slovenia) one of the most interesting rivers in Europe. Roman bronze vessels and iron weapons found by chance in the Ljubljanica at Vrhnika, the ancient Nauportus, led the director of the Provincial Museum in Ljubljana, Karel Dežman, to devise a large scale plan for an underwater survey of the riverbed. This, one of the first modern research projects of underwater archaeology was executed in 1884 with the help of divers from the Austro-Hungarian naval base in Pula. Investigations by the Group for Underwater Archaeology and the activities of amateur divers from 1979 onwards revealed distinctly structured distributions of underwater finds on several sites in the upper course of the river indicating possible sacred places with votive offerings and funeral sites, as well as other non-ritual concentrations.  相似文献

This paper explores the reasons behind the omission of historic acoustic values from heritage assessments in Australia. Best practice dictates that all cultural heritage values associated with significant places should be assessed in order to make informed conservation and management decisions. However, the multi‐sensory nature of aesthetics has been reframed in guidance documentation in ways that run counter to the primary frame. Conventions that have developed around the way places are assessed also work against comprehensive identification of values. As a result, the consideration of aesthetics in cultural heritage is limited to contemporary visual qualities. Furthermore, because the assessment of historic value takes a diachronic rather than synchronic approach, we have little knowledge of the places past communities valued for the sounds they experienced there. Research into landscape preference and acoustic ecology highlights the importance of identifying the inherent acoustic dimension of places and the role sound plays in developing a sense of place. Two landscape areas in Western Australia's south‐west with historic acoustic values, the Boranup Sand Patch and the Lower Reaches of the Blackwood River, illustrate how historic soundscapes can provide insightful contrasts and resonances with contemporary values, and how vulnerable such places are when the sound of place is overlooked in land management policies.  相似文献

The flexible sponge/epoxy composite can wrap underwater artefacts in any shape and forms a protective shell after curing, thus effectively wrapping and reinforcing the artefacts. However, the hydroscopicity of the sponge itself limits the underwater application of the sponge/epoxy composite. In this study, a novel polyurethane sponge was prepared by modified with super-hydrophobic multi-wall carbon nanotubes (SH-MWCNTs@PU sponge). Compared with the pristine PU sponge, the water-contact angle on the surface of SH-MWCNTs@PU sponges increased from 103.3 ± 1.82 to 152.6 ± 1.54o, and oily epoxy resin was able to cover the surface completely. The study shows that when SH-MWCNTs@PU sponges/epoxy resin composite material is used underwater, it prevents both water from entering the sponge and also the inside epoxy resin from overflowing into the water. Moreover, the composite materials have excellent toughness after reinforcement under water (flexural strength = 3.56 MPa) and the soft sponges can be moulded to wrap any type of underwater artefacts. In the laboratory, when taking a broken, three-dimensional blue-and-white porcelain pot as a research subject, the entire retrieval process—temporary stabilization, packaging, extraction and reinforcement material removal—was simulated to evaluate systematically all the technological aspects of safely excavating fragile underwater relics.  相似文献

Abstract

The general purpose of the international reburial project, Reburial and Analyses of Archaeological Remains (RAAR), is to evaluate reburial as a method for the long-term storage and preservation of waterlogged archaeological remains. Since 2001 material samples have been buried, retrieved, analysed systematically, and the results reported.

RAAR has mainly focused on the degradation of materials commonly encountered on archaeological sites, and on environmental monitoring techniques in order to determine what type of material can be reburied and for how long. The project has concluded that a heritage institution could provide short- or long-term curation for its archaeological archive by using reburial depots provided they are set up according to guidelines and restrictions stipulated by the RAAR project.

However, there are management and legal aspects that need to be discussed and resolved before each reburial project. Actual reburials that have been carried out so far are often a solution to emergency situations and lack collection and management policies. The questions ‘what’, ‘why’, and ‘for how long’ have been forgotten and need to be addressed. The legal protection of a reburial site is also important. This paper discusses these aspects and their consequences and highlights possible differences in approaches between the countries involved in the RAAR project.  相似文献

The ancient anchorage of Dor, Israel, contains wreck-sites from several periods. Underwater exploration of one Byzantine wreck discovered the remains of a medium-size boat constructed with iron nails. Coin-finds dated it to c .665 AD, after the Muslim conquest. The wreck was probably caused by natural agents, but an event in the Byzantine-Muslim conflict can not be discounted. The artefacts include a group of objects testifying to the practice of light-fishing. Literary sources indicate a prevalence of light-fishing, but archaeological finds are very rare. This discovery clearly indicates light-fishing in late antiquity. A sounding-lead and steelyard can be seen as auxiliary to the fishing.
