Endangered maritime archaeology in North Africa – the MarEA Project
Maritime cultural heritage in the Middle East and North Africa (MENA) is increasingly threatened by conflict, climate change, and urbanization. The Maritime Endangered Archaeology (MarEA) Project, launched in 2019, addresses this crisis by rapidly assessing vulnerabilities and aiding management strategies for at-risk sites. A key finding highlights the dual approach of MarEA: a generalized threat assessment applied across all sites, demonstrated through the historic port of Suakin (Sudan), and a site-specific shoreline change analysis to evaluate coastal erosion impacts, showcased at the UNESCO World Heritage Site of Sabratha (Libya). This methodology provides a comprehensive framework for preserving maritime heritage under mounting pressures.
The Detachment Physical Weathering Form Group Affecting Stone Building Materials at The Archaeological Site of Sabratha, Northwest Libya
A comprehensive analysis of the Archaeological Site of Sabratha, a UNESCO World Heritage Site in Libya, reveals that nine primary physical weathering forms—belonging to the 'detachment group'—are significantly affecting its stone monuments. These weathering processes, ranging from non-visible damage (0 degrees) to moderate damage (3 degrees), are primarily driven by diurnal and seasonal temperature variations, relative humidity fluctuations, salt crystallization, moisture content, and water exposure. The study employed a methodology based on the classification system developed by Fitzner and Heinrichs (2002, 2004), which includes fifteen individual weathering forms. To visualize damage distribution, contour maps were created for each form, alongside linear and progressive damage indices. The findings underscore the urgent need for government institutions to prioritize the preservation of Sabratha's built heritage, given the severity and extent of the observed weathering damages.
Impact of coastal environmental conditions on building materials of The Roman Theater at the archaeological site of Sabratha, Libya.
Coastal environmental conditions significantly impact the durability of building materials at Sabratha's Roman Theater, leading to structural degradation such as collapsing and disintegration. The study reveals that limestone, marble, and mortars used in the theater's construction undergo alterations due to exposure to coastal elements. Analytical techniques like XRD, XRF, PM, and SEM were employed to identify mineral composition and its changes, alongside evaluating physio-mechanical properties. These findings highlight the vulnerability of monumental structures in harsh coastal environments, offering insights into preservation challenges for UNESCO World Heritage Sites.
