Preserving Pavlopetri
The submerged prehistoric town of Pavlopetri, Laconia, Greece, offers a unique lens through which to examine the interplay between coastal environmental dynamics and the preservation of underwater cultural heritage. This paper explores the ongoing threats to Pavlopetri, including natural forces such as sediment transport, wave action, and storm surges, as well as human-induced impacts from boat traffic and coastal infrastructure. By integrating a…
Documenting Change on the SS Thistlegorm, Red Sea, Egypt
The SS Thistlegorm, a British World War II cargo vessel sunk in 1941 in the Red Sea, is one of the world’s most visited wreck dives, attracting thousands of divers annually. This popularity has accelerated structural deterioration and artefact loss through unsustainable mooring practices, looting, and unintentional diver impacts. The Thistlegorm Project—a collaboration between Alexandria University and the University of Edinburgh—conducted high-r…
Iron Age construction and Early Medieval reuse of crannogs in Loch Awe, Argyll
Despite its influence on Scottish crannog studies, absolute dating evidence for activity on the crannogs of Loch Awe has been lacking. This paper presents previously unpublished radiocarbon dates from six crannogs in the loch. Of these, five sites have provided dates within the 1st millennium BC, confirming the existence of Iron Age crannogs in the loch – four of which may have been occupied contemporaneously. The dates fit in to the now widely a…
Rising from the Depths Network
The Rising from the Depths (RftD) network aims to identify the ways in which Marine Cultural Heritage (MCH) can contribute to the sustainable development of coastal communities in Kenya, Tanzania, Mozambique and Madagascar. Although the coastal and marine heritage of eastern Africa is a valuable cultural and environmental resource, it remains largely unstudied and undervalued and is subject to significant threat from natural and anthropogenic pro…
Brochs and beyond
Completely unknown until 1975, when it was revealed during the construction of a new road, Old Scatness is a multi-period site that has provided unequivocal evidence dating broch construction to the mid first millennium cal BC, alongside a firmly dated sequence that is crucial to understanding the long Iron Age in Atlantic Scotland. Excavations were carried out at the site between 1995 and 2006 by local volunteers and staff and students from the …
The Ocean Decade Heritage Network
The Decade of Ocean Science for Sustainable Development 2021–2030 is a UN initiative that promotes a common framework for supporting stakeholders in studying and assessing the health of the world’s oceans. The initiative also presents a vital opportunity to improve the integration of archaeology within the marine sciences. With the First Global Planning Meeting of the Decade held in Copenhagen at the National Museum of Denmark in May 2019, steps …
Using Sector-Scan Sonar for the Survey and Management of Submerged Archaeological Sites
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 mak…
Mapping Submerged Archaeological Sites using Stereo-Vision Photogrammetry
Creating photo-mosaics and plans of submerged archaeological sites quickly, cost-effectively and, most importantly, to a high level of geometric accuracy remains a huge challenge in underwater archaeology. This paper describes a system that takes geo-referenced stereo imagery from a diver-propelled platform and combines it with mapping techniques widely used in the field of robotic science to create high-resolution 2D photo-mosaics and detailed 3…
An Iron Age crannog in south-west Scotland
As part of the second phase of the South West Crannog Survey, the crannog in Loch Arthur, New Abbey, Dumfries and Galloway, was surveyed and small-scale excavations were carried out on submerged eroding deposits. The crannog was seen to be at threat from erosion for a number of reasons, including insect infestation, aquatic plants and wave action. The eroding deposits were sampled and their ecofactual content analysed and structural timbers from …
A 1st millennium bc Atlantic roundhouse in Argyll
A detailed survey of the Atlantic roundhouse at Loch Glashan was carried out over two weeks in June 2003 alongside a small excavation to assess the extent of damage caused by encroaching vegetation and to obtain dating evidence. The structure is a large dry-stone circular building located above Loch Glashan, and the excavations produced architectural evidence suggesting more than one phase of occupation, alongside Iron Age artefacts and radiocarb…
The Atlantic Iron Age
Underwater Excavation at Ederline Crannog, Loch Awe, Argyll, Scotland
A trial excavation was carried out on the near-submerged crannog at Ederline Boathouse, Loch Awe, in July 2004. A trench measuring 3 × 5 m was opened on the northern side, in c.3 m of water. Around 1 m of organic deposits was encountered, along with structural timbers and animal bones. Despite a previous 4th century BC radiocarbon determination from a structural timber, a sherd of E ware from a sealed context gives an Early Historic date for the …
The Scottish Wetland Archaeology Programme
The Scottish Wetland Archaeology Programme (SWAP) was established to promote coherent research projects concerned with the investigation, preservation and manage- ment of the Scottish wetland resource. Two such research projects began in 2002. The Moine Mhór Cultural Heritage Project is concerned with developing methods to establish the location and extent of wetland deposits using predictive modelling techniques and other non-invasive methods of…
Excavations on a Bronze Age Cairn at Hardendale Nab, Shap, Cumbria
The cairn on Hardendale Nab was excavated in 1986 in advance of destruction by quarrying, and this allowed the reconstruction of a complex sequence of development. Construction of the cairn appears to have begun in the Early Bronze Age, although it might have been earlier. Phase 1 comprised a simple cist burial, and small earthen mound, with a number of secondary burials made in and around the original monument. Unusual rectangular features might…

A survey of crannogs in the Lake of Menteith, Stirlingshire
Identifies four sites with the aid of aerial photography, side-scan sonar survey, echo-sounding and underwater exploration by divers
Islets through Time
Scottish crannogs or lake dwellings are considered to be structurally varied sites with an extremely wide distribution, used from the neolithic up until at least the 17th century AD. As a result assumptions about the dating and form of individual sites are considered impossible without excavation. This paper demonstrates that the current classifications lack utility and that the long chronology view is misleading. It is suggested that there is a …
The Iron Age Enclosures and Prehistoric Landscape of Sutton Common, South Yorkshire
The Early Iron Age enclosures and associated sites on Sutton Common on the western edge of the Humberhead Levels contain an exceptional variety of archaeological data of importance not only to the region but for the study of later prehistory in the British Isles. Few other later prehistoric British sites outside the East Anglian fens and the Somerset Levels have thus far produced the quantity and quality of organically preserved archaeological ma…
