The subject of the paper is well outside the mainstream, and interesting for its methodological approach, the way it connects cave hydrology to air permeability of sedimentary rock, and the relevance for the protection (or lack thereof) of prehistoric cave art.

Short summary
Conservation of decorated caves is highly dependent on airflows and is correlated with rock formation permeability. We present the first conceptual model of flows around the Paleolithic decorated Cosquer coastal cave (southeastern France), quantify air permeability, and show how its variation affects water levels inside the cave. This study highlights that airflows may change in karst unsaturated zones in response to changes in the water cycle and may thus be affected by climate change.
