Underwater Cultural Heritage at Risk? Global Insights into Deep-Sea Mining and Trawling Impacts
Deep-sea mining for technology-critical minerals and expanding bottom-contact fishing threaten underwater cultural heritage (UCH). This study evaluates global exposure of UCH to these activities by integrating open-access datasets on seabed extraction, geoscience, and shipwreck locations. Documented shipwrecks are concentrated in the North Atlantic, while the Southern Ocean contains fewest documented sites. Most wrecks (95%) lie in shallow epipel…
Societal value of seagrass from historical to contemporary perspectives
Seagrasses have been entwined with human culture for millennia, constituting a natural resource that has supported humanity throughout this history. Understanding the societal value of seagrass fosters appreciation of these ecosystems, encouraging conservation and restoration actions to counteract historic and predicted losses. This study overviews the plethora of seagrass use in human history, ranging from spiritual and ceremonial roles, direct …
Climate Change Impacts on Wetland Archaeology: Mapping Drought and Assessing Wood Deformation in Åmosen, Denmark
Here we quantify the tolerance of archaeological wood to drying by analyzing in situ deformation during a severe drought. Deformation began when matrix potential dropped below 0 kPa, with severe deformation below −50 kPa. At the study site, this corresponds to soil water contents (SWC) of less than 40% and 30%, respectively. Furthermore, we evaluate the feasibility of using either a high density of handheld surface SWC measurements or drone‐based…
Using Open-Data Portals, Remote Sensing and Computational Modelling to Investigate Historic Wreck Sites and Their Environments: 45 Years on from Muckelroy
We explored site formation processes at 549 shipwrecks in the North and Baltic Seas using multibeam echosounder (MBES) data and environmental/anthropogenic variables. Phase 1 classified the structural integrity of each wreck. Phase 2 used regression modelling to explore correlations between wreck class and environmental variables at individual sites. A best-fit model comprised depth, salinity, fishing intensity, and wreck year. In phase 3 multi-c…
Monitoring Erosion of a Submerged Stone Age Site and Its Implications for Managing Underwater Cultural Heritage. A Case Study at Tybrind Vig, Denmark
Known locations with submerged and well-preserved Stone Age sites in Denmark are, in most cases, under constant threat of erosion. The results presented here have been gathered at Tybrind Vig by surveying a 165 m-long transect at 5-metre intervals from the shore, by measurements taken with a total station. To supplement this, the surrounding area was surveyed with an echo sounder/sonar unit that yielded 3D coordinates post-processed in GIS to inv…
Of time and tide: The Complex Impacts of Climate Change on Coastal and Underwater Cultural Heritage
The Intergovernmental Panel on Climate Change has documented wide-ranging changes to the world's coasts and oceans, with significant further change predicted. Impacts on coastal and underwater heritage sites, however, remain relatively poorly understood. The authors draw on 30 years of research into coastal and underwater archaeological sites to highlight some of the interrelated processes of deterioration and damage. Emphasising the need for clo…
Development of Predictive Geoarchaeological Models to Locate and Assess the Preservation Potential of Submerged Prehistoric Sites Using Remote Sensing, Palaeoenvironmental Analysis, and GIS
Using the Mesolithic site of Tudse Hage in the Great Belt of Denmark, this paper proposes a generic stepwise process to create geoarchaeological models that output seamless morphology maps in a GIS. This was achieved using remote sensing databases and the collection of marine geophysical data, above and below the seabed. On the basis of these data, key areas, with sediment sequences representative of the postglacial transgression surfaces, were i…
Characterizing the Preservation Potential of Buried Marine Archaeological Sites
The preservation potential of sediments from a submerged prehistoric site buried in a full marine environment was assessed using a combination of direct in situ measurements, measurements on extracted sediment cores and laboratory mesocosm experiments. The results show that first and foremost it is paramount to ascertain the state of preservation of the materials in the seabed—in this case wooden artifacts—that are to be preserved in situ. The re…
Rapid loss of endogenous DNA in pig bone buried in five different environments
The rate at which endogenous DNA from differently prepared (butchered, boiled and baked) compact pig bones degrades in five different Danish terrestrial and marine environments over 12 months was investigated. Although > 70% of the estimated endogenous mtDNA is lost after just four weeks of exposure, no cytosine deamination of DNA was recognised. A correlation between the presence of oxygen and the amount of preserved DNA was observed. The result…

Seagrass sedimentary deposits as security vaults and time capsules of the human past
Seagrass meadows form valuable ecosystems, but are considered to have low cultural value due to limited research efforts in this field. We provide evidence that seagrass deposits play a hitherto unrealized central role in preserving valuable submerged archaeological and historical heritage across the world, while also providing an historical archive of human cultural development over time. We highlight three case studies showing the significance …
