ODP Leg 208: Early Cenozoic Extreme Climates: the Walvis Ridge Transect

Figure 22

Stacked sonic waveforms. Examples of the problem encountered by the P-wave labelling algorithm, in 'slow' sediments, where the formation velocity approaches those of the drilling mud (left and center) and good picking in more consolidated formation (right). The black solid lines represent the results of the wave labeling algorithm.
