Abstract
Reverberation data collected during the CEAREX 89 experiment in the Greenland Sea are analyzed to describe the spatial variability of surface and bottom reverberation and estimate short‐range backscattering strengths. Features of the time‐azimuth decay of reverberation are identified by comparison with model propagation calculations, and backscattering strengths are estimated from the data using the measured reverberation and calculated propagation losses. Statistical measures of variability are applied in an attempt to characterize the spatial variability of surface (under‐ice) and bottom reverberation.
