Characteristics of the Mediterranean Seagrass Posidonia Oceanica Contributing to High-Frequency Acoustic Scattering

Abstract

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 vegetation and animal communities. Posidonia oceanica meadows are undergoing a slow but progressive regression, the most common cause of which is enhanced turbidity and the consequent reduction of water transparency. The first step towards the preservation of coastal environments is to define their extent and condition. Echographic surveys allow general maps to be obtained, but accurate seafloor characterization requires knowledge of the characteristics of seabed vegetation which affect acoustics propagation.
