Active oolitic sandbars like those in the Bahamas (Figure 1) exhibit complex internal architecture with a multitude of stacked sedimentary structures. Ooids are round, carbonate-coated grains that form in tropical climates. The internal anatomy of carbonate sandbars is often too complex to be captured in one- and two-dimensional data. Outcrops, cores, and 2D geophysical profiles provide a limited vertical view of the geologic record. Depositional processes are confined to the momentary subhorizontal boundary surface between sediment and water or air. Vertical 2D views limit the visibility of features developed on subhorizontal surfaces, making interpretation of 3D internal anatomy...
