Syria's coastal and nearshore zone contains a significant, but under-researched, record of maritime cultural heritage (MCH) ranging from prehistory to the present. This is exemplified by a lack of underwater investigations, but also limited investigation of key onshore maritime sites such as ports and harbours. There is also a lack of specialist in-country management regarding maritime cultural heritage research and protection. This situation has been worsened by the ongoing conflict (since 2011), which has reduced (already limited) field investigation. To assist in the advancement of Syrian maritime archaeology, this paper presents a baseline assessment which makes use of a geospatial database generated from satellite imagery as well as both published and grey literature. This assessment reviews past coastal environment changes affecting the Syrian littoral, and then highlights past disturbances and potential future threats impacting the MCH. This is done through analysis of all coastal/nearshore sites documented to date and showcased in more detail using two case studies: Tabbat al-Hammam and Ras Ibn Hani. This enables discussion of the current state of Syrian maritime archaeology and suggests ways forward for its future management and investigation. [ABSTRACT FROM AUTHOR]

Tropical cyclones are among the most detrimental hazards to the environment, societies, and economies, each year affecting millions of people and resulting in substantial casualties and material destructions in coastal communities. In this context, maritime cultural heritage, encompassing material evidence for the engagement of people with the sea, both on land and under water, is particularly vulnerable. Despite the significant number of archaeological sites exposed to tropical cyclones and other extreme sea-level events, maritime cultural heritage in the MENA region is rarely included in coastal vulnerability indices or incorporated in mitigation strategies, disaster management, sustainability, and resilience policies. In this study we examine the impact of tropical cyclones on the maritime archaeology of Oman with emphasis on the Dhofar region. This paper builds on existing coastal research in the Dhofar region—an area identified as the most cyclone-prone administrative region in Oman, but also an area that contains substantial archaeological remains. Central among Dhofar's maritime cultural heritage is Al-Baleed, a Medieval seaport with unparalleled evidence of engagement with international trade networks. [ABSTRACT FROM AUTHOR]

For millennia, the Middle East and North Africa (MENA) region has been a culturally dynamic zone, bounded by maritime societies dependent on the sea for communication, trade and livelihoods. The archaeological evidence of these past societies represents an extraordinary physical legacy of human endeavour and presence across this region, contributing to senses of place, identity and belonging amongst contemporary coastal communities. However, the coastal landscapes and marine environment of the MENA region are undergoing a period of profound change, associated with large-scale human development and climate change. In order to assess this change and the level of impact on the resource, the Maritime Endangered Archaeology project (MarEA) was established in 2019 to document cultural heritage sites and landscapes across the coastal and near-shore zones of the survey region. This paper introduces the work of the project and outlines a series of case studies presented in this volume that are representative of the variety and depth of work being undertaken within the project.

Conservation of historic shipwrecks is prohibitively expensive and in situ preservation and recording are the preferred archaeological approaches. Non-destructive high-definition 3D imaging is therefore essential for recording and managing submerged historic shipwrecks. Multibeam echosounders (MBES), the standard tool for hydrographic survey, can produce point clouds to image complex 3D structures. However, wreck imaging is often done using MBES in traditional survey mode optimised for morphological characterisation of the seafloor. This does not necessarily provide high-definition imagery required by archaeologists. This study demonstrates key factors influencing high-definition MBES imaging of wrecks through a controlled field experiment. Results show that optimal high-definition 3D imaging is achieved through maximising the pulse rate, narrowing the angular sector, using the highest frequency and shortest pulse lengths, applied to at least 3 to 5 overlapping centreline-parallel and offset passes with additional perpendicular/oblique lines. Variations in survey design are demonstrated to exert strong controls on sounding density and distribution, with high-density on horizontal and vertical wreck surfaces enabled by a combination of overlapping passes and offset lines. Adoption of this method would result in more widespread high-definition 3D imaging of wrecks to benefit archaeological research and develop effective mitigation strategies to minimise loss of the fragile underwater resource.

In recent years, increased attention has been turned towards the role of coastal environments in facilitating the global dispersal of humans. Previous approaches have focused on locating, dating and linking coastal archaeological sites, in order to create an overall impression of population movement across continents. When considerations of the actual process of colonization have been presented, they have been predicated on a series of assumptions regarding the nature of the coastal environment. The most important of these is that the coastal zone is homogenous and stable, on space and time scales relevant to human migration. This paper aims to test this and other assumptions by considering the true nature of the palaeo-coastal zone on global to continental scales and on timescales commensurate with migrating populations. Evidence is presented from Pleistocene and Holocene palaeo-environmental and archaeological records, so covering the major migrations of the Palaeolithic and Mesolithic. The principal conclusion of this study is that the coastal zone is in fact characterized by a significant degree of environmental heterogeneity and instability on a multitude of spatio-temporal scales. This in turn has significant implications for how we interpret the actual process of colonization. [ABSTRACT FROM AUTHOR]

The original version of this article was revised: Additional correction in Table 1: please delete (') in the second column heading was incorrectly carried out. It should read "Acquisition settings test"; by this, the author meant only to delete the apostrophe symbol, not the entire second column heading. [ABSTRACT FROM AUTHOR]
