During the cruises of R.V. VARUNA in the Laccadive Sea, observations were carried out on bio-acoustic scattering in the shallower depths off the atolls as well as on the Deep Scattering Layers (DSL) in the oceanic areas between Minicoy and Agathi Islands, off Pitti, Kavaratti, Kalpeni, and Androth Islands. Three Simrad Echo-scunders were used for obtaining continuous traces on echograms from different depth ranges for finding out the characteristics of the DSL before and after dusk, before and after dawn, and at different hours during day as well as at night.
