A recording of depth or distance under water made by an echo sounder.
- ‘An echogram of the kind pioneered by Maurice Ewing shows this clearly.’
- ‘With radar, sonar, fish-finders and echograms she could pinpoint and capture whole schools of fish with chilling effectiveness.’
- ‘Dives of exactly the same appearance were also evident in echograms recorded when the AUV was unattended; it is data from those dives that are considered in this paper.’
- ‘A small bowel series, a computed tomography scan, and an abdominal echogram revealed a mass in the terminal ileum along with multiple nodules in the liver.’
