Signatures of bad data

Contents:

• (relatively) Clean ADCP data
• Acoustic (noisy) Noise
• Bad weather / heavy seas
• Acoustic Interference
• Underway Bias in Averages
• Underway Bias in Singleping data
• Underway Bias due to bad scale factor
• Heading error causes cross-track errors
• Scattering Layer
• Electrical noise (spurious signal)
