Maritime Aspects of Medieval Siraf,Iran: a pilot project for the investigation of coastal and underwater archaeological remains

Siraf is well‐known archaeologically and historically as an ancient port in the Persian Gulf that prospered during the medieval period. Siraf played a leading role in facilitating maritime and terrestrial trade, connecting long‐distance Indian Ocean and China routes with those in the Gulf region. Despite its history, no previous research has been dedicated to the maritime infrastructure of Siraf. Through the ‘2012 Siraf pilot project’ a preliminary survey of the underwater and shoreline remains of this ancient port city was conducted. The site's location is unique in many respects to trade routes and logistical considerations; however, its maritime infrastructure is difficult to assess in light of the extensive threats to the site.     

Fishing Gear from a 7th-Century Shipwreck off Dor, Israel

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.

Florida’s Underwater Archaeological Preserves: Public Participation as an Approach to Submerged Heritage Management

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.     

The 4th-century B.C. shipwreck at Mazotos,Cyprus: New techniques and methodologies in the 3D mapping of shipwreck excavations

Abstract

Well preserved ancient shipwrecks are rare in the archaeological record, but when discovered, they can provide valuable information on a wide range of research issues if analyzed and documented properly. In this paper we discuss the significance, potential, and constraints of mapping methods applied during the underwater excavation of shipwreck sites with special emphasis on stratigraphy, documentation of finds, and reconstruction of site formation processes. As a case study, we present the digital photogrammetry and computer vision software programs used in the excavation of the 4th-century b.c. shipwreck at Mazotos, Cyprus. Our goal is to develop a targeted documentation and mapping method of ongoing shipwreck excavations so that others can address complex research questions concerning this unique discipline of archaeology.     

The Australian Historic Shipwreck Preservation Project: In situ Preservation and Long-Term Monitoring of the Clarence (1850) and James Matthews (1841) Shipwreck Sites

Increasingly, archaeologists are opting for on-site examination, reinterment, and in situ preservation of underwater cultural heritage sites as the first option in the management of sites at risk, as opposed to the more traditional excavation, recovery, conservation, and display/storage methods. This decision will inevitably be based on significance assessment, degree of perceived risk, and resourcing issues. However, long-term monitoring must become an integral part of these management programmes in order to quantitatively evaluate the effectiveness of the in situ preservation techniques employed. In 2012 the Australian Historic Shipwreck Preservation Project (AHSPP) was awarded a large Australian Research Council (ARC) Linkage Grant, enabling ten partner organizations and three Australian universities to collaborate in one of the largest multi-organizational maritime archaeology projects to be undertaken in Australia to date. One of the major aims of the project is to develop a protocol for the excavation, detailed recording and reburial of significant shipwrecks under threat, fostering a strategic national approach for the management of underwater cultural heritage (UCH) sites at risk. Two historically significant shipwreck sites that are considered under threat were chosen for this longitudinal comparative study — the Clarence (1850) located in Port Phillip Bay, Victoria; and the James Matthews (1841) which lies in Cockburn Sound, Western Australia. Both sites have been preserved in situ using two very different but innovative remediation strategies. More importantly, long-term monitoring programmes have been implemented on both sites, which will characterize changes in the reburial environment and the effect on the reinterred materials. In this way, the efficacy of both in situ preservation techniques will be systematically tested, providing a comparative analysis of practical protocols for the long-term protection and management of underwater cultural heritage.     

A Critical Analysis and Philosophical Review of ‘Rapid Reburial’: the Clarence project

In 2012, Australian cultural heritage practitioners and conservation scientists collaborated on a national underwater cultural heritage (UCH) reburial project, known as the Australian Historic Shipwreck Preservation Project (AHSPP) funded by the Australian Research Council. This resulted in the excavation, documentation and reburial of the ‘at risk’ shipwreck Clarence. Following the excavation, the site and associated artefacts were reburied and subsequently covered by shade cloth and finally, with polyvinyl chloride (PVC) tarpaulins. After completion of the in situ reburial, a number of critical issues were put into sharp relief including: what constitutes the accurate identification of a site as being ‘at risk’; and the implications of ‘rapid reburial’.     

A Late Antique Ceramic Assemblage at Burgaz,Datça Peninsula,South‐west Turkey,and the ‘Normality of the Mixed Cargo’ in the Ancient Mediterranean

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.     

Mapping Submerged Landscapes Using Multibeam Bathymetric Data: a case study from the north coast of Ireland

This paper outlines work currently being undertaken to reconstruct submerged archaeological landscapes off the north coast of Ireland. This research uses the recently‐completed Joint Irish Bathymetric Survey (JIBS), which has provided full‐coverage high‐resolution multibeam bathymetric data for the sea‐bed off the north coast. This data has been examined for evidence of past sea‐level change and been used to produce palaeo‐geographic reconstructions of the past landscape, which in turn have facilitated the identification of ten areas of high archaeological potential. The results presented here will form the basis of a future programme of archaeological survey and prospection. © 2010 The Authors     

Two Late Roman Wrecks from Southern Cyprus

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.

The Odyssey Case: press,public opinion and future policy

The Odyssey Case refers to the dispute between Odyssey Marine Exploration Inc. (OME) and the Kingdom of Spain in the US courts to determine the ownership of more than 500,000 coins, as well as other artefacts, that OME recovered from a wreck‐site it had code‐named Black Swan. However, the process was much more than a dispute over the coins. It reflected many of the components involved in the protection of underwater archaeological heritage, especially when economic and political interests are at stake. Written from the perspective of an archaeologist working for the regional authority responsible for developing archaeological policy, this paper tries to assess the case's impact on future policy development.
