A plasma gun source has been successfully used to obtain sub‐bottom profiles. The profiles show better penetration than with a 3‐5 kHz source and more resolution than with an air gun. The plasma gun source is compact, self‐contained, and requires no complex auxiliary equipment. The device was deployed from large research vessels and a small boat. The plasma gun produces sufficient acoustic energy and with its characteristically short pulse length and broad bandwidth it is an attractive sub‐bottom profiler, especially in shallow fresh or salt water.
