Combustive sound source (CSS) data collected on single hydrophone receiving units; in water depths ranging from 65 to 110 m; during the Shallow Water 2006 experiment clearly show modal dispersion effects and are suitable for modal geoacoustic inversions. CSS shots were set off at 26 m depth in 100 m of water. The inversions performed are based on an iterative scheme using dispersion-based short time Fourier transform in which each time-frequency tiling is adaptively rotated in the time-frequency plane; depending on the local wave dispersion. Results of the inversions are found to compare favorably to local core data. © 2008 Acoustical Society of America;
