Why do we measure water depth in fathoms? Do you ever get the feeling that you are in over your head? That you just can't fathom something? That, in short, it's too deep? There is something so elemental about the ocean depths that we embrace it as a metaphor for the unknown or the unknowable.

The ocean environment is divided into two broad categories, known as realms: the benthic realm (consisting of the seafloor) and the pelagic realm (consisting of the ocean waters). These two realms are then subdivided into separate zones according to the depth of the water.

Measuring water depth: Echosounding ... Soundings are now made by sending a sound pulse into the water. To use sound to measure water depth we need to know how sound travels through the ocean. The speed of sound depends on the temperature of the water, its salinity, and the pressure (which is equivalent to depth below the...

ACRS 1989: Oceanography; Water depth determination from satellite data ... Remote sensing from satellites appears to hold promise for obtaining depth information in shallow coastal waters. In this paper the physical principles, an optical model and algorithm for water depth determination from remote sensing techniques are given.
