Mapping the landscape of marine cultural heritage research from 2000 to 2023: A bibliometric analysis

As our understanding of the world's ocean and their history deepens, research on Marine Cultural Heritage (MCH) is increasingly vital for the preservation and maintenance of our shared cultural legacy. This paper conducts a bibliometric analysis of global MCH literature from January 1, 2000, to November 2, 2023, using Web of Science and VOSviewer. The results reveal three particularly interesting trends. Firstly, a significant increase in the volume of publications related to MCH research since 2018. Researchers in this field primarily hail from the Global North, particularly European countries, with their affiliated institutions displaying an international and diverse research profile in the MCH domain. Secondly, MCH research spans various disciplinary fields, including oceanography, environmental studies, ecology, and anthropology, forming the foundation for comprehensive MCH research. It encompasses a spectrum from traditional ecological knowledge to the impacts of climate change, extending to the influence of international law and policies. Thirdly, research hotspots in the MCH field include cultural heritage and climate change, coastal resilience and management, underwater cultural heritage, heritage conservation, and sustainable tourism, as well as Geoheritage and Geotourism. Building upon the bibliometric analysis, we provide suggestions for future research endeavors, emphasizing potential areas for further exploration and investigation.
