Abstract: The presence of subterranean conduits within the Woodville Karst Plain is inferred from statistical analysis of several sets of microgravity measurements. In addition to determining the locations of such conduits, their approximate relative depths and sizes are estimated as well. An iterated non-linear least squares method is used to fit observed gravity data to a proposed theoretical model for the conduit-gravity relation. The spatial density of the conduits is examined with respect to their relative cross-sectional areas. A known conduit’s presence is verified via the proposed method.
