A high-resolution seismic-reflection survey was run on the Mississippi River using marine common-depth-point (CDP), digital, and multichannel techniques in an attempt to locate a possible fault that had been interpreted by others from magnetic and land seismic data to be in the vicinity of Lock and Dam No. 26.

Audio bit depth. An analog signal (in red) encoded to 4-bit PCM digital samples (in blue); the bit depth is four, so each sample's amplitude is one of 16 possible values. In digital audio using pulse-code modulation (PCM), bit depth is the number of bits of information in each sample, and it directly corresponds to the resolution of each sample.
