  "term": "Bathymeter",
  "field": "Meteorology and atmospheric science",
  "definition": "An instrument used for measuring the depth of a body of water, such as an ocean, sea, or lake. Modern bathymeters are typically echo sounders that operate by transmitting a sound pulse (a ping) from the surface and measuring the time it takes for the echo to return from the bottom. The depth is calculated based on the two-way travel time and the speed of sound in water.",
