Figure 21. Box-whisker plots of laboratory-measured porosity of whole-core samples (modified from Cunningham, 2004). See figure 20 for an explanation of box-whisker plots. Box-whisker plots
are for samples from the following ground-water flow classes: horizontal conduit ground-water flow
class (GWFC2); leaky, low-permeability ground-water flow class (GWFC3); and diffuse-carbonate
ground-water flow class (GWFC4); and arranged according to sampling from subtidal cycles (HFC4
and HFC5) of the Miami Limestone and vertical position within upward-shallowing brackish- or
freshwater-capped cycles of the upper part of the Fort Thompson Formation.
