Acoustic experiments were conducted in order to quantifi the scattering properties of the most common Mediterranem seagrass, Posidonia Oceanica. Measurements were made over a wide range of frequencies and grming angles at several sites near the islands of Elba and Sardini~Italy, and in Saros Bay, Turkey. Results of these measurements indicate that, for dense fields of Posidonia, mean scattering strength values are quite high (-23 dB re 1 m2) with a relatively flat grazing angle dependence.
