Description
Summary:The data from the SACLANTCEN June 1986 Cruise is analysed to characterise sound-propagation environment. The cruise was conducted in the Faeroese Channel and the southern Norwegian Sea as the initial cruise of the Atlantic Inflow Experiment. The sound propagation environment of the upper portion of the water column is described. The mixed layer is defined in terms of the density, Brunt-Vaisala frequency, temperature, and in terms of the sound velocity minimum. The sound-velocity profile and the characteristics of its horizontal distribution are described. The importance of wind and vertical heat flux to the mixed layer is discussed relative to its distribution.
