Abstract :
Seabed properties are determined using a matched field geoacoustic inversion approach with towed, horizontal array data. Towed acoustic systems are advantageous because they are easy to deploy from a ship and the moving platform offers the possibility for estimating spatially variable (range-dependent) seabed properties. In this paper inversion results using measured, towed array data are presented. Simultaneously collected vertical array data are also inverted and used for comparison
