A Multisensory Analysis of the Moisture Course of the Cave of Altamira (Spain): Implications for Its Conservation

A novel multisensory analysis reveals how moisture dynamics within the Cave of Altamira threaten its Paleolithic cave paintings. The study identifies critical zones of humidity infiltration and dripping, particularly influenced by the dolomitic layer and central fracture, which vary in their preservation impact depending on whether they are sealed with calcium carbonate or actively dripping. Using advanced remote sensing techniques—including 3D laser scanning, ground-penetrating radar, photogrammetry via unmanned aerial vehicles, and high-resolution terrestrial methods—the research provides a detailed spatial mapping of moisture pathways. This approach offers targeted insights for conservation strategies to mitigate water-induced deterioration in rock art, benefiting both professionals and researchers.
