Characteristics of the mediterranean seagrass Posidonia oceanica contributing to high-frequency acoustic scattering
Acunto, Stefano; Lyons, Anthony P.; Pouliquen, Eric (NATO. SACLANTCEN, 2000/05)Posidonia oceanica meadows are the most important ecosystem for the life cycle of coastal Mediterranean benthos with a fundamental role in the primary production of the neritic system and a decisive influence on other ... -

Mechanisms for subcritical penetration into a sandy bottom: experimental and modelling results
Maguer, Alain; Bovio, Edoardo; Fox, Warren L. J.; Pouliquen, Eric; Schmidt, Henrik (NATO. SACLANTCEN, 1998/05)This paper presents the results of a recent study whose overall objectives are to determine the mechanism(s) contributing to subcritical acoustic penetration into ocean sediments, and to quantify the results for use in ... -
Penetration of acoustic waves into sandy seafloors at low grazing angles: the Helmholtz-Kirchhoff approach
Pouliquen, Eric; Lyons, Anthony P.; Pace, Nicholas G. (NATO. SACLANTCEN, 1998/08)The Helmholtz-Kirchhoff integral is applied to model the penetration of sound waves into sandy seafloors at grazing angles above and below the critical angle. Although the conditions for the validity -

Time-evolution modelling of seafloor scatter: Part 1: Theory
Pouliquen, Eric; Bergem, Oddbjorn; Pace, Nicholas G. (NATO. SACLANTCEN, 1997/04)A time-series model for acoustic seafloor backscattering is described. -
Time-evolution modelling of seafloor scatter: Part 2: experimental verification
Bergem, Oddbjorn; Pouliquen, Eric; Canepa, Gaetano; Pace, Nicholas G. (NATO. SACLANTCEN, 1997/04)A time-evolution model of seafloor scatter is numerically implemented and experimentally verified. The model is based on expressing analytically the elementary time-backscattered response of every seafloor surface and every ...
