11: Seabed Geoacoustic Structure at the Meso-Scale
نویسندگان
چکیده
The observational approach is based on direct path measurements of seabed reflection and scattering. The key advantages of this approach are: 1) high resolution vertically, 0.1m and laterally: inner scale of ~10m and outer scale of 100 km; 2) it substantially reduces uncertainties from the space/timevarying oceanography and biology due to short path lengths; 3) it requires a low source level, 4) can be hosted on an Autonomous Undersea Vehicle (AUV), permitting observations of 3D meso-scale features, and making it an attractive eventuality as a survey tool. A cartoon of the system is shown in Figure 1.

Seabed Geoacoustic Structure at the Meso-Scale
The approach includes both theoretical and measurement components. One measurement approach exploits the very high geoacoustic information content in direct path measurements of seabed reflection and scattering. Another measurement approach, based on long-range reverberation, has much less information content but is nonetheless a powerful way to explore scales inherent in the seabed. Both kinds...

متن کامل12: Bayesian Inversion of Seabed Scattering Data
The long-term goals of this work are to improve ocean acoustic reverberation modeling and sonar performance predictions in shallow waters by developing inversion procedures to estimate seabed scattering and geoacoustic properties with uncertainties, as well as investigating the importance of various scattering processes. Important issues include: investigating the angular and frequency dependen...
متن کامل11: Geoacoustic Inversion in Shallow Water
The ability to predict transmission loss of sound propagating in shallow water is constrained by the knowledge of the geoacoustic properties of the bottom. The long term objectives of this research project are related to the investigation of experimental methods and inversion techniques for estimating parameters of geoacoustic models of the ocean bottom and the associated uncertainties in the m...
