Basic Concept: Fathometer surveys determine water depths by repeatedly transmitting seismic energy through the water column and recording the arrival time of the reflected energy from the water bottom. The instrument calculates the water depth from these data and prints a depth value as a continuous graphic profile. Most fathometers use a narrow bandwidth 200 kHz seismic signal. They provide accurate depth information, but very little information about the subbottom. Fathometers that use a lower frequency, e.g., 20 kHz, can detect reflections from subbottom interfaces such as the bottom of an infilled scour hole.

What does fathometer measure?
A fathometer measures the depth of water by sending sound waves to the seafloor and calculating the time it takes for the waves to return. This information is then displayed on a screen in terms of depth measurements.
Fathometer is used to measure?
Ocean depth
What did Reginald Fessenden invent?
Fessenden's InventionsHe invented the radio and Fathometer
What does a fathometer measure?
A fathometer measures the depth of water by using sound waves to calculate the distance between the sensor and the seafloor. It is commonly used on boats and ships for navigation and safety purposes.
When was the first echo sounding device created?
The first echo sounding device, known as a fathometer, was created in 1912 by Reginald Fessenden. It used sound waves to measure the depth of water beneath a boat.
if you need to see water depths and navigation routes for travel on water, you need to get a?
To know water depths you need a fathometer. For navigation GPS is recomended.
What is the depth of the sea when a ship receives the sound produced by its fathometer after 3.5 second?
The speed of sound in water is roughly 1.5 km per second. You need to multiply the time by the speed to get the total distance traveled. Then - since the sound has to move back and forth - you divide that result by 2.
What tool would be used to measure the water depth at the edge of a pond?
A fathometer.
What is Electronic depth-sounding equipment which allowed scientists in the 1920's and later to precisely measure the ocean depth?
The equipment is called a "fathometer" or "echo sounder." It works by emitting sound waves from a transducer on a ship, which bounce off the seafloor and return to the transducer. By measuring the time it takes for the sound waves to return, the depth of the ocean can be accurately determined.
