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.

Not every relation is a function. But every function is a relation. Function is just a part of relation.

The cubic function.

Range

A formula or graph are two ways to describe a math function. How a math function is described depends on the domain of the function or the complexity of the function.

a Fathometer measures the sea depth

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.

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.

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.

To know water depths you need a fathometer. For navigation GPS is recomended.

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.
