The echo sounder, a device used for measuring the depth of water by emitting sound waves and timing their return, was first discovered in the early 20th century. The exact year of discovery can be attributed to various inventors and researchers who contributed to the development of this technology.
What else can I help you with?
How do you calibrate the echo sounder?
Echosounder calibration is an involved process and should be well understood before embarking upon it.
What echosounder use for?
Echosounders are primarily used for measuring the depth of water. They use sound waves to determine the distance between the sensor and the seabed or any underwater object. This technology is commonly used in navigation, fishing, hydrography, and oceanography.
How do you map ocean floors?
Hydrographic surveyors (as people who map the ocean floor are called) typically utilize sonar systems to measure water depths. The simplest form is a single beam echosounder mounted on the underside of a boat floating on the surface. Like a flashlight that illuminates a small area in the direction it is pointed, a single beam sonar is pointed down and ensonifies a small area on the seafloor beneath it. The echosounder emits a pulse of acoustic energy into the water. This energy will travel down through the water; when it hits the seafloor (or anything else in the water column) some of the energy will be reflected back towards the echosounder. The speed of sound in water varies based on temperature, salinity and pressure, but is usually in the neighborhood of 1500 meters per second. By measuring the amount of time it takes for the acoustic energy to make its round-trip journey, and multiplying it by the speed of sound in water, we are able to calculate the depth.
What is the past tense of discovered?
The past tense of "discovered" is "discovered."
