Sound speed profile means the sound speed-depth function. It is measured either directly by sound speed meters (subsect. 3.2.3.3.1) or by determinations of temperature, salinity and depth (subsect. 3.2.5.3).
25 Νοε 2022 · The sound speed profile (SSP) refers to a sets of sound speed values at different depths and at specific latitude and longitude coordinates, which represents a column vector.
Sound channels are levels in the ocean that trap sound waves. A sound channel can occur anytime there is a minimum in a vertical sound speed profile. The deep sound channel occurs deep in the ocean, typically at depths around 3000 ft. Secondary sound channels also occur, typically at shallower depths.
