Scientific paper

In this study, these variable density algorithms were applied to acoustic data acquired at a site known to contain the buried skeletal remains of a dinosaur. For one of the algorithms tested, images of object function and normalized density and compressibility of a buried bone were reconstructed that exhibited image sharpness consistent with the frequencies employed. In addition, the images of this bone, that was subsequently excavated, properly render its size and location and yielded qualitatively correct density and compressibility.
