Description The oceanic environment is the biggest biome on earth and its biota plays a
significant role in global, biological and chemical cycles. (Lawrence and Katherine,
1995). Most of the world's oceans with the exception of the Arctic and Antarctic and
possibly parts of the Central Pacific have a region at depth that reflects or scatters
sound. This is known as the Deep scattering layer (DSL). The Deep scattering layers
in the oceans were first recognized in 1942. The DSL is a layer of living organisms
ranging from about microscopic zooplankton, shrimps, meso pelagic fishes and
cephalopods that prey on one another. This layer migrates vertically in the water
column depending on light intensity and occurs at depths between 230-800m during
the day and 50-100m depth during night. The DSL is an important ecosystem of the
world oceans and supports a wide assembly of zooplankton, macro and micro nekton.
