        "note": "An echo sounder or sonar measures the two-way travel time, so the distance to the bottom or target = sound speed × time ÷ 2 (the sound goes out and comes back). At a typical 1,500 m/s, a one-second round trip is 750 m away. The accuracy rests on the assumed sound speed, which is why survey-grade echo sounders measure the real sound-speed profile (see /v1/sound-speed) rather than assume it.",
